Bolivian Valentinite


Valentinite is Antimony Oxide (Sb2O3) and was named in 1845 after the mythical monk and alchemist Basilius Valentinus. Some of these are "textbook", tabular, monoclinic examples of Valentinite crystals as illustrated in Atlas der Krystallformen by Victor Goldschmidt. The luster and gemminess of these crystals are superb. Not all the specimens have great aesthetics or crystal size, but this is a rare mineral, and with rare minerals come some good and some bad, like all minerals. The only difference is that there are a lot less of these in the world than a lot of other species.

Enjoy !!
