Brilliant, gemmy, INTENSELY LUSTROUS crystals to 3 cm, are perched atop a thin plate of quartz matrix. This is an extremely good specimenfor the locality in that the crystals are the best possible luster and brightness, the piece is pristine, and the overall sparkly look of it is impactful more so than most. Several central 3-cm crystals are doubly-terminated. In person it is much brighter and prettier than on this screen.
