The Crystal Park area in Colorado has produced many fine mineral specimens and this nice Topaz and Biotite combination specimen is one of them! A 3.2 cm, glossy brown-black Biotite crystal is offset by an etched, champagne colored Topaz and sits perfectly on its own for display. The Biotite has a textbook, pseudo-hexagonal shape and there is a cluster of small Biotite crystals at its base on the back side. The Topaz has great color and glassy luster with a very intricate form produced by late-stage etching subsequent to its crystallization. The two make a great complementary pair. Good Biotite crystals from this area are not at all common and neither is this combination... from anywhere! It is a superb display miniature, and the only problem is deciding which species to put on top. Ex. Thomas Campbell collection with label.
