“The Viridias pendant is from a body of work inspired by the sensuous and organic jewelry of the Art Nouveau movement,” says Jessica Dow. She and Mark Anderson fabricated Viridias from Argentium Sterling Silver, a 13-carat Andamooka matrix opal that Anderson cut, and a one-carat natural tourmaline. The hand-engraved pendant is 1/2 x 2 in. (13 x 51 mm). This piece appeared in the July 2008 issue.
