Right off, let me say that this big, gemmy topaz crystal has been slightly polished, on at least many faces, to a silky luster. But the forms of the natural faces have been preserved. Not only is this a BIG, GEMMY light-amber crystal of topaz - but you have these super-sharp, slender black schorl crystals shooting through its center, making this crystal really spectacular! It weighs over 300 grams!
