A spectacular example of Dioptase included with Quartz, accompanied by some wonderfully formed Calcite.
The Quartz has great luster and clarity. The Dioptase is exceptionally colorful and gemmy. The Calcite is the subtle kicker, on the right of the specimen you might suddenly notice some more opaque crystals that are remarkably lustrous as well. 
The architecture of the specimen is also just delightful. Overall just  great specimen. As such I may have done a video that shows it in every possible light. 😅
