Can Lab Grown Diamonds be Appraised?
Lab grown diamonds have rapidly become a sophisticated and popular choice for fine jewelry, offering the same chemical, physical, and optical properties as natural diamonds—often at a more accessible price. But as their popularity grows, so do the questions surrounding their value. Chief among them: Can lab grown diamonds be appraised? And more importantly—should they be?
At Nazar’s & Co. Jewelers, we believe every piece of jewelry deserves expert care and professional valuation. In this blog, we’ll explore what goes into appraising a lab grown diamond, why it’s an essential step for owners and collectors, and how it can protect your investment for years to come.
Why You Should Appraise a Lab Grown Diamond
1. Protect Your Investment
An appraisal provides a formal record of your diamond’s value, which is critical if you ever need to file an insurance claim due to loss, theft, or damage. Even though lab grown diamonds tend to be more affordable than natural ones, they still represent a significant financial and emotional investment—especially when featured in custom engagement rings, heirloom pieces, or fine jewelry designs. Without an appraisal, your insurance provider may only offer minimal compensation based on estimates, not the actual value of your diamond.2. Ensure Proper Insurance Coverage
Insurance companies typically require a current appraisal document before they will cover jewelry under a homeowner’s, renter’s, or specialized jewelry policy. This document gives the insurer a clear understanding of what they’re protecting—and ensures you receive accurate coverage for replacement or repair. At Nazar’s & Co. Jewelers, we offer professional appraisal services to help you secure the protection your jewelry deserves.3. Understand the Full Value of Your Jewelry
A diamond’s worth goes beyond its price tag. The craftsmanship of the setting, the designer label, and the rarity of the cut or design all play a role in determining value. A comprehensive appraisal provides a holistic look at your piece—ideal for those interested in estate planning, resale, or upgrades.What Factors Influence the Appraisal of a Lab Grown Diamond?
Appraising a lab grown diamond follows a process similar to that of natural diamonds, though with some distinct market considerations. Here’s what expert appraisers take into account:1. The 4Cs (Cut, Color, Clarity, Carat Weight)
- Cut: Determines how well the diamond interacts with light—critical to its brilliance.
- Color: Graded on a scale from D (colorless) to Z (light yellow).
- Clarity: Evaluates internal and external imperfections (inclusions and blemishes).
- Carat: Measures weight, which often corresponds to size.
2. Diamond Shape and Rarity
The shape—whether round, oval, emerald, cushion, or pear—can impact the stone’s desirability and price. Uncommon cuts, such as Asscher or marquise, may hold higher appraisal values due to limited availability or design uniqueness.3. Certification and Grading Report
A lab grown diamond accompanied by a GIA, IGI, or GCAL report gives appraisers a trusted baseline to work from. These certifications detail the diamond’s essential features and confirm its authenticity and origin. Though a certification isn’t the same as an appraisal, it complements the valuation process and helps ensure a fair and accurate result.4. Mounting and Metal Type
When appraising a finished piece—such as a ring, pendant, or bracelet—appraisers also assess:- Type of precious metal (platinum, 18K or 14K gold, etc.)
- Craftsmanship quality
- Design complexity and whether the piece is part of a designer collection or in-house custom jewelry
5. Current Market Trends
Lab grown diamond pricing evolves with the market. Appraisers evaluate similar stones and retail listings to determine up-to-date replacement value, which may be higher or lower than the original purchase price depending on supply, demand, and market shifts.When Should You Get Your Lab Grown Diamond Appraised?
- Right after purchase, to ensure you have a current value for insurance
- Every 2 to 5 years, as values fluctuate with the market
- After a repair or reset, especially if the piece has been altered
- Before gifting or passing it down, for estate and legacy planning
