Early history of Diamond Registry

Nissan Perla, Preseident and Ceo of Diamond RegistryThe Diamond Registry was founded in 1961 by Joseph Schlussel, and started out as a monthly newsletter with thousands of subscribers that served to publish industry related information, such as wholesale diamond price updates, diamond trends, and developments in the diamond market. In 1997, The Diamond Registry was the first diamond information center on the internet, and became the main entrance to the world’s loose diamonds inventory and the primary source for diamond information.

In 2009, Nissan Perla took the position as CEO of the online diamond business after the passing away of the founder and his dear friend Joseph Schlussel. Since then it has grown into the go-to online source for high-end buyers and sellers with offices in New York, Israel and Hong Kong.

The service that the Diamond Registry provides

The Diamond Registry provides high quality service by creating a bridge between the wholesale diamond industry and the consumer. Through The Diamond Registry the consumers can buy GIA certified loose diamonds at wholesale prices. In addition, the consumers can create jewelry with a highly experienced team of in-house jewelry designers from a trendy 3 carat diamond ring to a very popular princess cut engagement ring. In other words, the service gives the public more control and allows them to buy diamonds closer to the source which means they do not have to pay the inflated retail prices of “branded diamonds”. With over 50 years of experience, The Diamond Registry has proven a reliable, careful, precise and personal service.
