Jewelry Store In Locust Valley
Le Joaillier Fine Jewelry is an independent, family-owned jewelry store in Locust Valley 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.
