Tourmaline (89 grams) (ex Rolando Gioia Collection)

Item Description

A beautiful display piece featuring a group of dark green (Verdelite) Tourmaline crystals free of matrix. There are six main crystals that have terminations, and only one of them is incomplete. The terminations have an interesting "rounded" appearance with an opaque black hue, but the entire piece is not opaque, as you can see areas of olive green and even a bit of emerald green shining through. A very attractive, colorful, display specimen. Weigh is 89 grams. Valued at $1200. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
