In hopes of a better life and more opportunity, Samuel Grunberger, a Slovakian immigrant, settled in Antwerp, Belgium in the 1930s and founded Grunberger Diamonds, Inc. However, Samuel had to halt production and close his company’s doors during World War II in order to escape religious persecution and the Nazi’s sweeping reign.

When the war ended, Samuel, who fled Belgium with his wife and son, Marcel, returned to a recovering Antwerp with no business and very little money to his name. But it was his tenacity and grit that gave him the strength to rebuild his company, which then became the moral and ethical foundation Grunberger Diamonds, Inc. stands on today.

The strength of an individual like Samuel was impressive; however, it was the support of family that eventually made this business the world’s largest producer of AGS 000 Ideal Cut, Hearts and Arrows melee.

Today, Grunberger Diamonds is still owned and run by Marcel and his family. As each generation joins the family business, and as the business expands to different corners of the world, the Grunberger's understand the importance of remaining authentic, ethical, and consistent.

David Grunberger, the grandson of Marcel, tells us more about Grunberger Diamonds’ AGS membership.
