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.
