This extraordinary natural bi-color tourmaline is cut in a nearly square octagon shape and presents a highly unusual color display: the body is largely transparent and near-colorless, with warm orange-golden tones concentrated at the corners, and a striking multicolored prismatic reflection is visible within the stone under direct light, creating a spectacular spectrum of colors trapped within the crystal. This optical phenomenon is the result of natural internal fractures acting as prisms inside the stone.

From Africa and completely untreated, this I3 clarity stone is very heavily included, which is precisely the source of its visual drama. It is a specimen and collector piece rather than a conventional faceted gem, and would be spectacular in a crystal-style bezel setting or wire wrap that allows light to enter from all angles. A genuinely unique tourmaline for those who seek the extraordinary in natural minerals.
