A most unusual and interesting Quartz specimen. The color ranges from clear to almost white to a light smoky color to small patches which are quite dark. Much of the specimen is composed of double terminated crystals which in places have grown on underlying, elongated crystals on which they form scepters on the terminations of the underlying crystals. Elsewhere, the double terminated crystals are stacked upon each other. There are two distinct parts to the specimen. There is a stack of crystals which start at the base, curve outwards and then back inwards to connect with the main body of the specimen which leaves a hole in the middle. The most interesting part, is the main crystals underneath the main body of the specimen. These are elongated and formed between now absent, Calcite crystals. The resulting pseudomorph Quartz crystals are quite thin and have an unusual bladed habit at the termination reminiscent of Barite. The surfaces of the specimen have a good, glossy luster.

Condition: Very Good

Flaws: There are some small internal cleaves just below the surface.
