For over 70 years and three generations, the Grandview Klein Diamond Group (GKD) has been renowned for its diamond cutting expertise and devotion to its clients.
Our philosophy is simple: to provide every client with the perfect diamonds. Our access to superior rough diamonds as well as our state-of-the-art factories around the world allows us to deliver the most exquisitely cut stones to our clients.
Our dedication to craftsmanship, trust, and integrity has led us to become one of the largest diamond manufacturers and direct suppliers worldwide, boasting sales offices in New York, Tel Aviv, and Hong Kong.
With an extraordinary inventory of the finest quality diamonds (specializing in +1 ct), exceptional stones, hard-to-find items and unique diamond jewelry, GKD is an all- encompassing supplier to its retail partners.
An international diamond company proudly operated with the traditions and values upon which it was built - integrity, trust, dedication, and pride in craftsmanship – Grandview’s core philosophy is to provide its clients with diamonds that will satisfy the unique desire of every customer that walks through their doors.

From what began as a family-owned business on New York's 47th Street, GKD has since expanded its business globally, currently boasting sales offices in New York, Tel Aviv, and Hong Kong, with manufacturing facilities in New York, South Africa, Botswana and Namibia.
GKD is a leading supplier to High End Independent retailers in the US, Far East and Middle East, working with a select group of leading jewellery retailers on an intensive basis and, less intensively, with a further ~200 such companies.
