You just do not think of colemanite as something you could cut into a gemstone, but here you have a FINE 8 mm (2.47 carat) stone, obviously cut from a very unusual colemanite specimen with a gemmy area. It is presented here in a set with a very aesthetic crystal cluster of colemanite - not a clunky blob, as you usually see, but a cluster of elegant, tabular crystals! This is just a very unusual cut and rough set, and a prize for a California or rare cut stone collector. Once on display with other cut and rough sets in the Fallbrook, California museum.
