Cobalt Calcite Hand Polished Stones (1-2 Inch - A Grade - 16-24 Pieces Per Pound) Ethically Sourced from Democratic Republic of the Congo

This is quite rare material that doesn't come along very often as the region where these stones are mined is very remote and must be mined by hand. A few stones may even show green malachite or copper inclusions, but isn't guaranteed with each batch. Visually they appear to be tumbled stones, however these cobaltoan calcite crystals are all polished by hand leading to a very smooth surface and a more rounded shape.
