Our staff is required to continually improve upon their education and training by regularly attending seminars, lectures, and advanced gemological studies, including the coveted and highly regarded, Fellowship (FGA) through the Gemological Association of Great Britain.

Our goal is to not only accurately identify and evaluate unknown gemstones and their many possible treatments, but also to help make the entire jewelry buying process more informative and stress free.  Whether you are shopping in the Diamond District and would like to verify the many details about your jewelry item(s) before you buy, or you have recently purchased a piece from another retailer, cruise line, or auction, we are here to clarify the intricate process of buying gemstones and jewelry, while providing you with the accurate knowledge and a true, unbiased assessment of your item(s).

Considering the high cost of gems and jewelry, it just makes sense to have them looked at by professionals. We have saved our clients agonizing regret and thousands of dollars.
