Specimens and Rough

Most gem material must be cut and polished before it reveals its full beauty. But we sometimes find rough stone that is intrinsically beautiful in its natural form and has value as a mineral specimen. These pages also include parcels of rough stone suitable for cutting and some fine gem carvings.

All items are in stock and available for purchase
