Tourmaline (Verdelite) (53.17 grams) (ex Rolando Gioia Collection)

Item Description

An eye-catching, three-dimensional group of good quality, sharp, lusrous, gemmy prismatic Tourmaline crystals which show a beautiful green hue throughout most of the prisms when strongly backlit. For the most part, the specimen is in fairly good shape, but there are a few nicks and small imperfections here and there. Somewhat hard to photograph, and better in person! The specimen weighs 53.17 grams. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
