This superb specimen is a matched set consisting of both halves of a large crystal (itself, a floater.). The smaller section fits snugly atop the larger, and you can see that the crystal then tapered off at that lower edge, so nothing is missing on the shorter half. The color is very good for this material, and the polish is of high quality (unusually so). The inclusions are montmorillonite. Size given is for the largest crystal half. Ex. Pala International/William Larson Collection.
