About Us

Le Joaillier Fine Jewelry is an independent, family-owned business founded in 1961 in New York’s Diamond District. In 1979, we relocated along Long Island’s “Gold Coast” in Locust Valley.

Len Margolis, GIA Graduate Gemologist, is the second generation owner. His love of gems and beautiful jewelry, along with meticulous attention to detail, is reflected in the pieces that he purchases and creates.

Le Joaillier is a full service jewelry store specializing in antique repair and restoration of jewelry, watches and clocks.

Our top priority is to ensure all of your jewelry needs are met in a professional and courteous manner, while providing our customers with personalized service all at affordable prices.
