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.  This stone is a lovely example of this scarce material - many of these can be overly dark or poorly cut, not at all the case here.  A fine respectable size, very pleasant color and quite 'flashy'; this one is very nice.  Reasonably hard (7 on the Moh's scale) for a rarity as well.
