This is simply a superb octahedral crystal, of perfect form and classical color, from the famous Winterstock Mountain glaciers. It has remarkably good color, sharp form with almost no damage (a few small contacts is all I can see), and is complete 360 degrees around, one of the most perfect we know of in this size range. Minor adularia and granite matrix is attached to the bottom. The photo and video speaks for it...simply astonishing for the quality, and color.
