Jewelry designer Paula Crevoshay has donated her George Pendant to the Smithsonian’s National Museum of Natural History. It was accepted into the National Gem Collection during a ceremony attended by Crevoshay, museum director Cristián Samper, Crevoshay’s gem-expert husband Martin Bell, and National Gem and Mineral Collection curator Jeffrey Post.

The George Pendant is composed of a rare green zircon that comes from the Ratnapura Mines of Serendib, Sri Lanka. The 18k, one-of-a-kind, handmade pendant is accented with green tourmaline. The pendant was cut en cabochon by George Crevoshay, for whom the pendant was named.
