This sharp specimen is one of the finest single crystals I have seen in watching these trickle out for about a dozen years. It has exceptional sharpness, whereas most are rounded; and it also has a great surface luster, where most are matte finish. The even coloration and deep saturation also add to its qualities, and make it stand out from the others I have seen - many bigger, but not finer. From the noted pseudomorph collection of Ken Roberts. This is a rare replacement pseudomorph. Joe Budd photos
