This specimen is a competition-level, complete-all-around STUNNING miniature, with a cluster of three intergrown crystals to 3 cm long, perched on a small knob of matrix. It is STUNNING, visually, both for the luster and the sharp geometry of the piece. Complex bevelled terminations throw off reflections in ever direction. There is no damage except a teeny contact atop and a few contacts or breaks on the bottom peripheral crystals, while the major crystals are not only upright, but astoundingly 3-dimensional (more so in person!). This is a MAJOR miniature for the species, to my eye better in absolute quality than some Bristol or Wisconsin locallity specimens I have seen (and sold myself) for much more money over the years
