Our Story

Our Vision

Honesty and integrity were the foundations for the first Jewelry Judge appraisal lab opened by Mr. Barry Block in 1989 in Long Island, New York. For more than thirty years Barry has built his businesses on ethical standards, continuously providing his clients with product knowledge, professional guidance, and most importantly, value for their hard earned dollar.


Barry's industry experience began when he was seventeen years old, working under his father's wing. After honing his diamond grading skills and learning every aspect of the business the "old fashioned way," Barry moved on to the retail end of the trade.


Twenty-one years later, he moved from owning his retail store to opening his independent appraisal lab, The Jewelry Judge.


Barry's industry experience and education coupled with his sales expertise is the formula for professional success. His goal has always been to protect the jewelry purchasing public, as well as the honest reputable jeweler. Since opening his doors in 1989, Barry and The Jewelry Judge have earned the respect and admiration of an entire industry, as well as continuous accolades from his loyal clients.


Barry has spent years networking with many industry leaders, groups and associations to develop a fair and honest reputation widely accepted as the "gold"  standard in the jewelry industry.

The Jewelry Judge offers an appraisal service in your hometown.


Since opening the first Jewelry Judge office, in 1989, we have remained focused on accommodating both jewelers and their customers. We continously seek methods to improve the accuracy, consistency and professionalism of appraisals.
