Our Beginning

The Diamond Shop has been a household name in St. Louis since 1910. Joseph and Sirose Kohn acquired the store shortly after returning home from World War II, in 1948. Joe and his family have owned and operated the store for over 60 years now and have served St. Louis families for two, three, and even four generations.

In 1976, Joe’s son, Thom, became a resident graduate gemologist of the Los Angeles location of the world-renowned Gemological Institute of America (G.I.A.). Thom F. Kohn is the creative genius behind the Thomas Farley Designer Brand. Being raised in the industry gave Thom a drive and insight to create designs beyond “the norm” and with special attention to detail and superior craftsmanship. Thom creates many one-of-a-kind pieces based on the individual that will be wearing the piece thus reflecting the personality and uniqueness of each client.

Since Joe’s retirement, Thom and his wife, Mona, are continuing the Kohn family tradition of excellence in customer service as they and their seasoned sales staff and on-site jewelers proudly lead St. Louis towards the future of jewelry. Selling only the highest quality diamonds, The Diamond Shop offers both traditional and innovative settings by well-known designers, as well as unique pieces custom-designed at our store. The Kohn family strives to set their business apart from the over-saturated market by offering some of the industry’s most competitive prices in a pressure-free atmosphere.
