This big, gemmy topaz crystal looks for all the world at first glance like a giant euclase - due to the very rare ISOLATED blush of blue deep inside it, amidst the colorless gem material. This superb crystal is complete all around and finely terminated, with high luster. It weighs an impressive 181 grams. The interior is absolutely clear, with the blue blush in the center/bottom. A fine and really UNIQUE-looking gem topaz crystal!
