A diminutive blue-green Tanzanian gem with a bit of a surprise; the stone has some (likely Rutile) silk that casts a reflection across the table. It is a schiller that is not dissimilar to precipitated copper in other species; entirely invisible when not actively lit. A very fun and quite unique gem that we happened across in a parcel of less remarkable gems.
