Chrysoberyl (8.27 grams) (ex Rolando Gioia Collection)

Item Description

Some of the most classic Chyrsoberyl specimens in the world are those from Espirito Santo in the southeastern end of Brazil. This thumbnail with fine, yellow-green color, excellent luster, and good gemminess, has some deeply stiated faces and despite a few rough spots, is still very well-crystallized. It's doubly-terminated, but it's not complete all the way around as you can see from the photos. This 8.27 gram crystal is a rare, and highly sought-after specimen. It is a "classic," with good form and excellent gemminess. It's actually clean enough in areas to produce a few fine quality gemstones. From the collection of Rolando Gioia (a contributor to new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").
