Quartz (Var: Amethyst)
Jefferson Co., Montana, USA
Small Cabinet, 5.9 x 4.4 x 1.4 cm
Here is a very unusual old Montana amethyst specimen that came with an old Schortmann's label. It features a flat shard of colorless quartz, upon which have grown three flat, tabular, very gemmy crystals of amethyst, with multiple terminations (some of them conventional prisms) shooting out of their sides. Ex. Richard Hauck Collection.
