A big dramatic designer cabochon of top shelf Thunder egg agate from the Lucky Strike mine in Oregon. This one is unusual for a Lucky Strike with finely detailed white tubes surrounded by gorgeous fortification patterns in semi translucent chalcedony. An absolutely gorgeous gem and a very unusual example of this beautiful material. This stone has a glossy high polish front and back and has a great professional cut. Slightly beveled to facilitate setting, it will look terrific set in one of your designs or as a terrific addition to your collection. This stone measures 60x47 mm and is 7 mm thick, the weight is 132 cts. Don't let this one get awa! As always, Thanks for looking!
