THis is a doubly-terminated, floater crystal of imperisl topaz....quite rare in occurrence! It is almost complete on the display face, though it has a minor ding on a lower face and another on the backside. Still, it displays well and the completeness of the crystal is unusual as most crystals from here are broken at the base. 2.7 x 1.4 x 1 cm
