Octahedron is a polyhedron with eight faces. It is composed of eight equilateral triangles, four of which meet at each vertex.


They occur naturally in a variety of colours and sizes. As a shape it rates very highly for cutting and polishing, as a good octahedron will deliver two polished stones with a 50% of the stones original weight. The other 50% of off-cuts, will then be re cut. So a two carat stone will deliver one carat of polished diamond which maybe two by half a carat, or one at 0,75carat and one at 0.25carat. Its because of this high loss in the cutting process we advise you set the rough stone direct into jewellery.

We currently have in stock, Octahedrons of 0.15ct to 1.38ct in both brown and cape colour.
