Natural vs. Lab-Grown Diamonds: Understanding the Difference
Few changes have affected the modern diamond market as significantly as the rapid growth of laboratory-grown diamonds.
To the unaided eye, a high-quality lab-grown diamond can look virtually identical to a natural diamond. Both can display exceptional brilliance, both can receive laboratory grading reports, and both can be set into beautiful engagement rings and fine jewelry.
But when it comes time to determine value—particularly resale value—the distinction between natural and lab-grown diamonds becomes extremely important.
Natural and laboratory-grown diamonds originate differently, have different supply dynamics, and participate in very different resale markets.
For anyone considering selling a diamond, identifying which type you own is one of the first and most important steps in a professional evaluation.
If you'd first like to understand how buyers evaluate diamonds in general, read our Why Some Diamond Rings Are Worth Thousands More Than Others guide.
What Is a Natural Diamond?
Natural diamonds formed deep within the Earth under extreme heat and pressure.
The diamonds we recover today are the result of geological processes that occurred over extraordinarily long periods of time. They were eventually transported closer to the Earth's surface through volcanic activity, where they could later be discovered and mined.
Their natural origin and limited supply have historically been important components of their rarity and desirability.
But being natural doesn't automatically make every diamond highly valuable.
Professional buyers still evaluate characteristics such as:
-
Carat weight
-
Cut
-
Color
-
Clarity
-
Shape
-
Overall make
-
Fluorescence
-
Laboratory certification
-
Eye appeal
-
Current market demand
The combination of these characteristics helps determine how desirable a particular natural diamond is in today's marketplace.
What Is a Lab-Grown Diamond?
A laboratory-grown diamond is created in a controlled technological environment rather than forming naturally within the Earth.
Modern producers generally use one of two processes:
-
HPHT — High Pressure High Temperature
-
CVD — Chemical Vapor Deposition
These processes create diamonds with essentially the same crystal structure and many of the same physical and optical properties as natural diamonds.
This distinction is important.
A lab-grown diamond isn't the same thing as a cubic zirconia or traditional diamond simulant.
It is a diamond—but its origin is laboratory-grown rather than natural.
That difference in origin has major implications for supply, pricing, consumer demand, and resale value.
Can You Tell the Difference Just by Looking?
Usually, no.
This is one of the most important things diamond owners should understand.
A properly produced lab-grown diamond can look virtually identical to a natural diamond when viewed with the unaided eye.
Even experienced jewelry professionals may need specialized equipment, laboratory documentation, or additional testing to confidently determine origin.
That's why appearance alone should never be used to determine whether a diamond is natural or laboratory-grown.
Professional buyers use a combination of:
-
Magnification
-
Diamond screening technology
-
Laboratory grading reports
-
Laser inscriptions
-
Gemological characteristics
-
Specialized testing when necessary
We'll explore these identification methods in greater detail in Part 2.
Why Origin Is One of the First Things a Buyer Determines
Imagine two diamond engagement rings sitting next to each other.
Both feature a beautiful round brilliant diamond.
Both weigh approximately two carats.
Both appear bright and attractive.
Both may even have similar color and clarity grades.
Yet their market values can be very different.
One of the first questions a professional buyer needs to answer is:
Is the center diamond natural or laboratory-grown?
Until that question is answered, accurately evaluating the diamond's market value is difficult.
Natural and laboratory-grown diamonds don't simply represent two versions of the same product at different retail prices.
They have developed into distinct marketplaces with different supply, pricing, and resale dynamics.
From the Buyer's Desk
Years ago, determining whether a diamond was natural was rarely one of the first questions a jewelry buyer needed to consider.
Today, it's essential.
Lab-grown diamonds have become increasingly common in engagement rings and fine jewelry, and high-quality examples can be extremely difficult to distinguish from natural diamonds by appearance alone.
That's why professional buyers don't guess. We identify the diamond first and evaluate its market only after we understand exactly what we're looking at.
Natural Doesn't Automatically Mean Valuable
Another misconception worth addressing is that any natural diamond must be valuable simply because it came from the Earth.
That's not necessarily true.
Natural diamonds vary enormously in quality and desirability.
A diamond's value can be affected by:
-
Poor cut quality
-
Low color grade
-
Significant inclusions
-
Unpopular shape
-
Fluorescence
-
Damage
-
Certification
-
Overall make
-
Current demand
A beautiful, desirable natural diamond may command a strong market value, while another natural diamond of similar size may be considerably less desirable.
This is why professional evaluation goes far beyond simply identifying a diamond as natural.
Our How Professional Jewelry Buyers Determine the Value of Your Jewelry guide provides a broader explanation of how these factors are considered when evaluating fine jewelry.
Lab-Grown Doesn't Mean "Fake"
Calling a laboratory-grown diamond "fake" isn't technically accurate.
Diamond simulants such as cubic zirconia and moissanite are different materials that are designed to resemble diamonds.
Lab-grown diamonds, by contrast, have essentially the same chemical composition and crystal structure as natural diamonds.
The important distinction is origin.
One formed naturally within the Earth.
The other was produced using technology in a controlled environment.
And while they may appear extremely similar, the markets that determine their values are very different.
That distinction becomes especially important when someone decides to sell.
Why This Matters Before You Sell
If you're considering selling a diamond ring, don't assume you know its origin based solely on appearance, what you were told, or how much was originally paid for it.
Documentation can be extremely helpful.
If available, look for:
-
A GIA grading report
-
Another recognized laboratory report
-
A laser inscription number
-
Original purchase documentation
-
An insurance appraisal
Even if you don't have paperwork, a professional evaluation can help determine what you own.
If you're considering selling a natural diamond or diamond engagement ring, you can Send Photos for a Quote for an initial review or Book a Private Appointment for a confidential evaluation.
Coming Up in Part 2
Knowing that natural and lab-grown diamonds can look nearly identical raises an obvious question:
How do professional buyers actually tell them apart?
In Part 2, we'll examine diamond screening technology, laboratory reports, laser inscriptions, magnification, and the professional testing methods used to determine whether a diamond is natural or laboratory-grown.
How Professionals Identify Natural and Lab-Grown Diamonds
If natural and laboratory-grown diamonds can look virtually identical, how does a professional buyer determine which one they're examining?
The answer increasingly involves a combination of experience, gemological knowledge, documentation, and specialized technology.
Years ago, identifying a diamond as natural was often relatively straightforward. Today, advances in laboratory-grown diamond production mean appearance alone is no longer enough.
A professional evaluation begins by establishing identity before attempting to establish value.
Why a Loupe Alone Isn't Always Enough
A jeweler's loupe remains one of the most important tools in diamond evaluation.
Under magnification, an experienced professional can examine characteristics such as:
-
Inclusions
-
Facet structure
-
Polish
-
Damage
-
Laser inscriptions
-
Manufacturing characteristics
-
Internal features
Certain inclusions or growth characteristics may provide clues about a diamond's origin.
But clues aren't the same as confirmation.
Modern lab-grown diamonds can be extremely convincing, and some don't display obvious characteristics that allow their origin to be confidently determined using magnification alone.
That's why professional buyers increasingly rely on multiple methods.
Diamond Screening Technology
Specialized diamond screening equipment has become an essential part of the modern jewelry industry.
These instruments analyze characteristics that aren't necessarily visible to the human eye and help determine whether a stone is consistent with a natural diamond or requires additional testing.
Depending on the technology being used, screening equipment may analyze a diamond's optical or spectroscopic characteristics.
The important distinction is between screening and definitive identification.
A screening device can help a professional determine whether a diamond passes as natural or should be referred for further examination. Certain stones may require more advanced testing before their origin can be conclusively established.
This layered approach is one reason professional identification is so important.
Laboratory Grading Reports
One of the most useful pieces of documentation you can bring to a diamond evaluation is a grading report from a respected gemological laboratory.
A grading report can provide information including:
-
Whether the diamond is natural or laboratory-grown
-
Carat weight
-
Color
-
Clarity
-
Cut grade when applicable
-
Measurements
-
Polish
-
Symmetry
-
Fluorescence
-
Additional identifying characteristics
The Gemological Institute of America (GIA) is one of the best-known independent gemological laboratories in the world.
A grading report provides valuable information, but a professional buyer will still verify that the report corresponds to the diamond being examined.
That brings us to another useful identification tool.
Laser Inscriptions
Many graded diamonds have microscopic information laser-inscribed on the girdle—the narrow outer edge of the diamond.
These inscriptions may contain a laboratory report number or other identifying information.
They're generally invisible without magnification.
During an evaluation, a buyer may examine the girdle and compare the inscription with the accompanying grading report.
This can help establish that the diamond being evaluated corresponds to the documentation presented with it.
However, the presence or absence of an inscription alone should never be treated as definitive proof of origin.
Not every natural diamond is inscribed, particularly older diamonds that may have been purchased long before laser inscription became commonplace.
Documentation is helpful.
Professional verification is still essential.
What If You Don't Have a Diamond Certificate?
Don't assume something is wrong simply because you don't have a grading report.
Many natural diamonds have never been submitted to a gemological laboratory.
This is especially common with:
-
Older engagement rings
-
Estate jewelry
-
Inherited diamonds
-
Vintage jewelry
-
Diamonds purchased decades ago
-
Smaller diamonds
An experienced buyer can still examine the stone and determine the appropriate next steps.
In certain situations, additional laboratory testing may be warranted.
The lack of paperwork doesn't automatically make a natural diamond less important or prevent it from being professionally evaluated.
Why Older and Inherited Jewelry Deserves Careful Examination
Inherited jewelry presents an interesting challenge.
A ring may have been purchased 30, 40, or 50 years ago and have no surviving documentation.
The original receipt may be gone.
The appraisal may have disappeared.
The grading report—if one ever existed—may no longer be available.
But the diamond itself remains.
This is where professional examination becomes particularly valuable.
Rather than making assumptions based on the age, setting, or appearance of the jewelry, an experienced buyer evaluates the diamond and supporting characteristics individually.
If you've inherited jewelry and aren't sure exactly what you own, our How Professional Jewelry Buyers Determine the Value of Your Jewelry guide explains how professional evaluations approach the entire piece rather than focusing on a single characteristic.
Identification Comes Before Valuation
This principle is worth emphasizing:
You can't accurately determine a diamond's market value until you know what it is.
A professional buyer may need to establish:
-
Is the stone actually a diamond?
-
Is it natural or laboratory-grown?
-
What does it weigh?
-
What are its color and clarity characteristics?
-
How well is it cut?
-
Is there a grading report?
-
Does the report correspond to the diamond?
-
Is the diamond damaged?
-
What is the current market demand?
Only after these questions are answered does meaningful valuation begin.
This is also why online estimates based only on carat weight can be misleading.
Two diamonds of identical weight may have completely different characteristics—and completely different markets.
Our Why Some Diamond Rings Are Worth Thousands More Than Others guide explores these valuation differences in much greater detail.
From the Buyer's Desk
Technology has changed the way professional diamond buyers work.
Experience and magnification remain incredibly important, but today's buyer also needs to understand modern diamond screening and verification.
When we're evaluating a diamond, we don't want to assume it's natural simply because it looks like diamonds we've purchased for decades. We want to establish exactly what we're looking at first.
Once we know that, we can begin evaluating the characteristics and market that actually determine its value.
Does Joseph Diamonds Buy Lab-Grown Diamonds?
No.
Joseph Diamonds specializes in purchasing natural diamonds and does not purchase laboratory-grown diamonds.
We include lab-grown diamonds in the Joseph Diamonds Knowledge Center because understanding the distinction has become an important part of modern diamond ownership and professional jewelry evaluation.
If you aren't sure whether your diamond is natural or laboratory-grown, documentation such as a grading report may provide the answer, and professional identification can help clarify what you own.

Coming Up in Part 3
Once a diamond has been properly identified, we arrive at one of the most important—and most misunderstood—questions in today's diamond market:
Why can natural and lab-grown diamonds that look so similar have such different market values?
In Part 3, we'll examine supply, rarity, production, consumer demand, retail pricing, and the secondary market to explain why natural and laboratory-grown diamonds follow very different value trajectories.
Why Natural and Lab-Grown Diamonds Have Different Values and Resale Markets
Once a diamond has been properly identified, the next question is usually:
Why can a natural diamond and a lab-grown diamond that look so similar have such different values?
The answer has much less to do with appearance than many people expect.
Natural and laboratory-grown diamonds may share many physical and optical properties, but they exist in fundamentally different markets. Their supply, production, consumer demand, retail pricing, and secondary-market dynamics aren't the same.
Understanding those differences is essential—especially if you're trying to determine what a diamond may be worth today.
The Fundamental Difference: Supply
Natural diamonds are a finite natural resource.
They formed deep within the Earth through geological processes that took place over extraordinarily long periods of time. Finding, mining, sorting, cutting, and bringing gem-quality natural diamonds to market requires significant resources.
Laboratory-grown diamonds are different.
Once the technology and equipment are available, additional diamonds can be produced in controlled environments using HPHT or CVD processes.
As production technology improves and manufacturing capacity expands, the potential supply of lab-grown diamonds can increase much more readily than the supply of comparable natural diamonds.
That difference in supply is one of the most important forces affecting their respective markets.
Why Lab-Grown Diamond Prices Have Changed
Lab-grown diamond technology has advanced rapidly.
Improved production methods, greater manufacturing capacity, increased competition, and expanding supply have affected the prices consumers pay for laboratory-grown diamonds.
This is why someone who purchased a lab-grown diamond several years ago may discover that a comparable newly produced diamond is available today at a substantially different retail price.
That doesn't mean there is anything physically wrong with the original diamond.
It reflects a changing market.
For this reason, it's important not to assume that the original purchase price of any diamond—natural or lab-grown—automatically represents its current resale value.
Natural Diamonds Have a Different Supply Dynamic
Natural diamonds aren't manufactured in response to demand.
A producer can't simply decide to create another supply of natural two-carat diamonds with a particular combination of color, clarity, cut, and shape.
What exists in the market ultimately depends on what nature produced and what can economically be recovered.
That doesn't mean natural diamond prices always increase.
They don't.
Natural diamond values can rise or fall depending on:
-
Consumer demand
-
Economic conditions
-
Diamond shape
-
Size
-
Quality
-
Wholesale inventory
-
Fashion trends
-
Global market conditions
But the underlying supply dynamics remain very different from those of laboratory-grown diamonds.
Retail Price Is Not Resale Value
This is one of the most important concepts in the entire guide.
The price paid at a jewelry store isn't the same as the amount an item can later be sold for.
Retail pricing may include:
-
Store operating expenses
-
Marketing
-
Sales commissions
-
Financing costs
-
Manufacturer and distributor margins
-
Warranty or service programs
-
Setting and mounting costs
A professional buyer isn't determining what the diamond originally cost.
The buyer is determining what that diamond can reasonably be sold for in today's secondary market.
This distinction applies to natural diamonds, lab-grown diamonds, and jewelry generally.
It's also why an insurance appraisal shouldn't be treated as a cash offer. Insurance values are generally intended to address replacement cost rather than immediate resale value.
For a deeper explanation of how professional buyers approach valuation, read How Professional Jewelry Buyers Determine the Value of Your Jewelry.
The Secondary Market Matters
A diamond only has a meaningful resale market when there are buyers willing to purchase it.
For desirable natural diamonds, an established secondary market includes professional diamond buyers, jewelers, wholesalers, dealers, and consumers looking for previously owned stones.
But not every natural diamond has the same demand.
A well-cut natural diamond in a desirable size, shape, color, and clarity range may be significantly easier to resell than another natural diamond with less desirable characteristics.
This is why professional buyers evaluate the specific diamond, not simply the word "natural."
Our Why Some Diamond Rings Are Worth Thousands More Than Others guide explores these differences in greater detail.
Why the Lab-Grown Resale Market Is Different
The secondary market for laboratory-grown diamonds operates differently.
One major reason is straightforward: buyers can often obtain newly produced lab-grown diamonds from an expanding supply.
When new comparable stones are readily available at competitive prices, there may be less incentive in the trade to purchase previously owned lab-grown diamonds.
This creates very different resale dynamics from the established market for desirable natural diamonds.
The market continues to evolve, which is another reason we avoid making sweeping promises about what any diamond will be worth years into the future.
At Joseph Diamonds, our focus is the market we know and specialize in:
We purchase natural diamonds. We do not purchase laboratory-grown diamonds.
What About the Setting?
Here's another important point that can easily be overlooked.
A lab-grown center diamond and the jewelry surrounding it are separate components of an evaluation.
For example, a ring containing a laboratory-grown diamond may still be made from:
-
14K gold
-
18K gold
-
Platinum
-
Designer jewelry
-
Natural accent diamonds
-
Other potentially valuable materials
The fact that Joseph Diamonds doesn't purchase lab-grown diamonds doesn't necessarily mean the entire piece should simply be dismissed.
The setting and any other qualifying components can have their own value and should be identified separately.
This is exactly why professional jewelry evaluations examine the entire piece rather than making assumptions based solely on the center stone.
A Grading Report Doesn't Establish Market Value
A grading report is extremely useful.
It can document important characteristics such as carat weight, color, clarity, cut, measurements, fluorescence, and diamond origin.
But a grading report doesn't tell you what someone will pay for the diamond today.
Two diamonds with similar grading information can still perform differently in the marketplace because of factors such as:
-
Overall cut quality
-
Proportions
-
Eye appeal
-
Shape
-
Fluorescence
-
Demand
-
Marketability
Think of the grading report as an important description of the diamond—not a price tag.
Be Careful With Online Diamond Calculators
Online calculators can be useful for general education, but they shouldn't be confused with an actual market evaluation.
A calculator may ask for:
-
Carat weight
-
Color
-
Clarity
-
Shape
-
Laboratory report
But it may not account adequately for the subtleties that influence real-world demand.
Professional buyers evaluate the complete diamond and then compare it with the market in which they actually buy and sell.
That's why two diamonds that appear almost identical on paper may still receive different evaluations.
From the Buyer's Desk
One of the most difficult conversations in today's diamond market happens when someone expects the original retail price to determine what a diamond is worth today.
We understand why. The purchase price is often the only number the owner has ever associated with the diamond.
But professional buyers have to evaluate today's market—not yesterday's receipt.
Our job is to first identify exactly what you own and then explain how the current market views it. With natural diamonds, that means looking far beyond carat weight and examining the combination of quality, desirability, certification, and current demand.
The Important Takeaway
Natural and lab-grown diamonds can be remarkably similar in appearance.
Their markets are not.
The differences in origin, supply, production, consumer demand, and secondary-market demand help explain why their values can behave very differently.
And within the natural diamond market itself, quality still matters enormously.
A natural diamond isn't valuable simply because it's natural.
The individual characteristics of the stone ultimately determine where it fits within today's market.
Coming Up in Part 4
In the final section, we'll bring everything together and explain what you should know before selling a natural diamond.
We'll cover:

What to Know Before Selling a Natural Diamond
If you're considering selling a natural diamond, understanding what you own is only the beginning.
The next step is understanding how the selling process works, what information is useful, and what you should expect from a professional diamond buyer.
You don't need to become a gemologist before selling your diamond. But knowing a few important things can help you ask better questions, understand an offer, and make a more informed decision.
Do You Need a GIA Report to Sell a Diamond?
No.
A GIA grading report can be extremely helpful, but it isn't required to have a natural diamond professionally evaluated.
Many diamonds—particularly older, inherited, and estate diamonds—were never submitted to a gemological laboratory.
Others may have been graded years ago, but the original paperwork has since been lost.
A professional buyer can still evaluate the diamond.
If you do have a grading report, bring it with you. It can provide valuable information about the diamond's:
-
Carat weight
-
Color
-
Clarity
-
Cut
-
Measurements
-
Polish
-
Symmetry
-
Fluorescence
-
Identifying characteristics
The report can also help confirm the diamond's natural origin.
But remember: a grading report describes a diamond. It doesn't determine what someone will pay for it.
Market value still depends on the characteristics of the diamond and current demand.
What Documentation Should You Bring?
You don't need extensive paperwork to have your diamond evaluated.
However, if you have documentation, bring it.
Helpful items may include:
-
GIA or other recognized laboratory grading reports
-
Original purchase receipts
-
Previous appraisals
-
Original jewelry boxes
-
Designer documentation
-
Repair or service records
-
Any information about the jewelry's history
Documentation can provide useful context, especially for designer or estate jewelry.
But don't worry if you have none of these things.
An experienced buyer should still be able to examine the jewelry and determine the appropriate next steps.
Insurance Appraisal vs. What Your Diamond Is Worth Today
This is one of the most common sources of confusion when selling a diamond.
You may have an insurance appraisal stating that your ring is worth a significant amount of money.
That number can be useful for insurance purposes—but it isn't necessarily what the ring can be sold for.
An insurance appraisal is generally intended to estimate the replacement cost of an item.
A professional buyer is evaluating its current market value.
Those are two very different numbers serving two very different purposes.
The original retail purchase price is also different from resale value.
A jewelry store's retail price may include overhead, marketing, sales commissions, financing, warranties, and retail profit margins.
When you sell a diamond, the question isn't:
"What did this cost originally?"
The relevant question is:
"What is this particular diamond worth in today's market?"
Should You Have Your Diamond Appraised Before Selling?
Not necessarily.
If your primary goal is to sell the diamond, paying for a formal insurance appraisal may not provide the information you're actually looking for.
An appraisal and a purchase offer serve different purposes.
A professional diamond buyer should be able to examine the stone, explain the important characteristics, evaluate current market conditions, and provide an offer without requiring you to obtain an appraisal first.
If you're unsure whether your diamond needs independent laboratory grading or additional documentation, an experienced buyer can explain whether taking that extra step makes sense.
Should You Clean Your Diamond Before an Evaluation?
You don't need to professionally clean your jewelry before bringing it in.
A light cleaning can make a diamond easier to examine, but professional buyers routinely evaluate jewelry in all conditions.
Avoid aggressive home cleaning methods, especially with antique or estate jewelry.
Some rings may contain delicate gemstones, older settings, or components that shouldn't be exposed to harsh chemicals or ultrasonic cleaning.
When in doubt, bring the jewelry exactly as it is.
What Happens During a Professional Diamond Evaluation?
The exact process depends on the diamond, but a professional evaluation may include:
-
Identifying the stone
The buyer first determines whether the stone is a diamond and verifies whether it is natural. -
Examining the diamond under magnification
This helps assess clarity characteristics, condition, inclusions, possible damage, and identifying features. -
Reviewing documentation
If a grading report is available, the buyer can compare the diamond with the report information. -
Verifying measurements and weight
Carat weight and dimensions are important components of valuation. -
Evaluating quality
Color, clarity, cut, shape, fluorescence, proportions, and overall eye appeal may all influence desirability. -
Evaluating the setting
The gold, platinum, natural accent diamonds, designer name, and overall jewelry construction may have value separate from the center diamond. -
Reviewing current market conditions
The buyer considers demand for comparable natural diamonds in today's market. -
Explaining the offer
A professional evaluation should help you understand why your diamond falls within a particular market range.
This is why a serious evaluation involves much more than placing a ring on a scale.
Does the Setting Have Value Too?
Often, yes.
When evaluating a diamond engagement ring, the center diamond isn't necessarily the only valuable component.
The setting may contain:
-
Gold
-
Platinum
-
Natural accent diamonds
-
Natural colored gemstones
-
Designer craftsmanship
-
Recognizable hallmarks
Certain designer or estate settings may also have value beyond their precious metal content.
That's why the entire piece should be examined before deciding how it should be valued.
For a broader explanation of this process, visit our How Professional Jewelry Buyers Determine the Value of Your Jewelry guide.
What If You're Not Sure Whether Your Diamond Is Natural?
Don't guess.
As we discussed earlier in this guide, natural and laboratory-grown diamonds can be extremely difficult to distinguish by appearance alone.
A grading report may provide the answer, but professional screening or additional testing may sometimes be appropriate.
It's particularly important to verify origin when dealing with:
-
Recently purchased engagement rings
-
Jewelry without documentation
-
Inherited jewelry with an uncertain history
-
Loose diamonds
-
Diamonds purchased online
Correct identification should always come before valuation.
Does Joseph Diamonds Buy Lab-Grown Diamonds?
No.
Joseph Diamonds purchases natural diamonds and does not purchase laboratory-grown diamonds.
We discuss lab-grown diamonds in this guide because understanding the difference between natural and laboratory-grown stones has become an essential part of modern diamond identification and education.
If a piece of jewelry contains a lab-grown center diamond, other components—such as gold, platinum, or qualifying natural diamonds—may still have value and can be evaluated separately.
Frequently Asked Questions
Can I sell a natural diamond without the original receipt?
Yes.
The original receipt isn't required for a professional evaluation. The diamond's current characteristics and market demand are far more important than its original purchase price.
Does a larger diamond always mean a higher value?
No.
Carat weight is important, but size is only one factor.
Color, clarity, cut, shape, certification, condition, eye appeal, and market demand can all influence value.
Our Why Some Diamond Rings Are Worth Thousands More Than Others guide explains this in much greater detail.
Do you buy loose natural diamonds?
Natural diamonds can be evaluated whether they're loose or mounted in jewelry.
Do I have to sell after an evaluation?
No.
A professional evaluation should give you the information you need to make your own decision.
Can I get an initial opinion without coming in?
Yes.
You can Send Photos for a Quote to provide photographs and information about your natural diamond or jewelry before scheduling an appointment.

From the Buyer's Desk
The best evaluations begin with information.
Before discussing price, we want to understand exactly what we're looking at—whether the diamond is natural, its quality, its condition, whether documentation exists, and how comparable diamonds are performing in today's market.
You should leave an evaluation understanding more about your diamond than you did when you arrived.
Whether you decide to sell is entirely up to you.

Final Thoughts
Natural and laboratory-grown diamonds can share remarkable visual similarities, but understanding their origin is essential when determining value.
For natural diamonds, a professional evaluation considers far more than carat weight. Quality, certification, cut, condition, marketability, and current demand all contribute to what a particular diamond may be worth today.
The most important thing is to know exactly what you own before making a decision.
