A slightly warped Tanzanite crystal makes up this specimen. It is in excellent condition, showing very little damage. Though it is somewhat warped- it looks as if 2 parallel crystals grew into each other- its orthorhombic prismatic form is still very good, with well-defined edges and clean faces that possess a vitreous luster. It has been heat-treated, but pleochroism is still visible, in that it has a pale violet color when viewed from some angles and a deeper, blue-violet color when viewed from others. It is transparent and moderately clear, containing a few large internal fractures, one of which reaches the surface in one or two areas. There is only a very small amount of a sulfide-laden host rock attached at its base.
