Tsavorite Tsavorite Tsavorite

Amazing cluster of Tsavorite crystals - rarely do you see clusters and rarer still complete floaters with no point of attachment (they almost always form on Graphite and usually one face of the Tsavorite will be contacted on covered with Graphite). Under a loupe I can find a couple tiny trivial dings, otherwise complete and undamaged. A fine Tsavorite specimen composed of four main crystals, largest is 1cm across. There are some Graphite inclusions, but the crystals are mostly gemmy and transparent.
