Faceted Cassiterite has always been an appealing member of the collector class of gemstones. It is a tin mineral that is rare in gem quality, but when cut is quite impressive - it has both a high refractive index and an adamantine luster. These are quite dispersive as well - when nice, they are really lovely stones. We were extremely impressed by this very fine example of the species - great size and beautifully cut. Additionally, the nice very light bodycolor helps to highlight the optical properites of the species. Reasonably hard (7 on the Moh's scale) for a rarity as well.
