An incredible piece for the size! This has the finest quality and gemminess you can ask for. the tips of the crystals are sharp, and lustrous, and to 4 cm. It has highest luster, gemminess, and just superb 3-D aesthetics! Marty was one of the locals around when Collectors Edge was mining this material, and bought one of the best of the finds. This IS superb, and worthy of the collection he built, and any other.
