About this Appraiser

For over 30 YEARS, GAL and its staff of expert Gemologists have built its reputation as one of the leaders in the industry. They offer a number of appraisals and comprehensive laboratory services to suit any of your needs.

All of their Gemologists are graduates of the Gemological Institute of America, including years of industry experience. Their staff are 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.

Their 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, they 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).

GAL now has a second location in Garden City, Long Island.
