Sparkling tiny crystals of pyrite accent only the edges of the beautiful translucent calcite crystals here, forming natural patterns that make you wonder how such a thing can form in nature. This material is simply a "classic" of Chinese finds, unique in style and quality to one single large pocket found sometime around 2011 as we remember it. The find is distinct to this day, slightly different in form and subtle style from all others. Rarely on the market today.
