This superb crystal is the best example, gram for gram, I have had of the species (or, seen). The piece is 3.3 cm tall. tilted, it fits in a TN box but if that is too big for the thumbnail collectors out there, I'd simply advise clipping the bottom nub off. The quality, the gemminess, the robust nature of the crystal, all combine to make this an exceptional piece. Again, for the species, I have seen bigger pieces, but just not of this quality in a gem crystal style suitable for the sophisticated collector as opposed to the species collector. It was formerly in the competition thumbnail collection of Ron Pellar. Joe Budd photos. ex Ron Pellar collection
