In 1978 a South African family specializing in fine diamonds for generations, opened their US office in Atlanta and Georgia Diamond Corporation was established.

For over 30 years in the US we have built a reputation as a source for the "best of the best" diamonds from around the world.

GDC is proud to be one of the few offices in the world invited to purchase their diamonds directly from De Beers. This sought after invitation [enjoyed by less than 100 merchants world-wide] makes it possible for us to offer the most beautiful diamonds in the world... year after year.

In addition to De Beers, we nurture priceless relationships we have had for generations with cutters in South Africa, Russia, Belgium and Israel, who manufacture to our exacting standards.

Since our inception GDC has been creating fine jewelry for an exclusive clientele. Our collection is presented under the Catherine Ryder brand and is prized by fine jewelers around the world.

Catherine Ryder fine jewelry is the difference between paint on canvas and a work of art. Each piece demonstrates structural integrity and a freshness borne of true craftsmanship.

As a flood of new self-styled 'designers' charge after the latest fashion craze - the Catherine Ryder brand offers a proud legacy of exceptional design and craftsmanship.

Fine jewelry for generations.
