A really fine and aesthetic sturmanite thumbnail from the N'Chwaning II Mine. Three, stacked, pagoda-like, hexagonal, honey-brown crystals form this piece. The crystal; shows an interesting concentric zoning. The top crystal is complete all-around and is undamaged and the bit of contacting on the lower crystals is on the back and out of sight. Ex. Rob Smith Collection.
