full in-house laboratory
We do it all
We verify, evaluate, and grade gemstones in accordance with strict GIA Guidelines. By assigning grades to gemstones that have been authenticated using GIA Grading Procedures, they can then be placed into a retail pricing category using Gemworld International's U.S. Wholesale Pricing Guide.
After the jewelry item is completely evaluated, it is then assigned a Retail Replacement Value for insurance purposes. We provide you with a digital copy and a hard copy upon request. A digital copy can be easily be stored and forwarded to your insurance provider.
Insurance appraisals can range from $75 to $250 depending on the item. Call ahead for pricing.
Wait. Do you have a commercial Laboratory report with that?
Authentication
You should have a Commercial Laboratory Report with your Gemstone. This reassures any buyer that the purchase being made is legitimate. It also reduces the price of an appraisal.
There are numerous laboratory facilities. We recommend the Gemological Institute of America (GIA), American Gem Society (AGS), and EGL USA (a reputable U.S. laboratory not to be confused with EGL international.)
Our In-house laboratory is fully capable of identifying and pricing all gemstones, gemstone treatments, synthetics, simulants, and assembled gemstones. We also provide diamond plotting services.

In 1982, Richard Drucker introduced the world's gemstone industry a colored gemstone pricing guide, now known as GemGuide. The publication, which is recognized as the industry leader for gem pricing and market information, is used for valuation and information in more than 40 countries by jewelers, appraisers, and as a reference in legal cases involving valuation.
