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 !!

No. Bltd 99 Val
VALENTINITE - $1,250 (SOLD)

This crystal is MONSTROUS for the species !! A magnificent, HUGE, sharp, lustrous, gem/gemmy crystal group. This is an incredibly large crystal of Valentinite (the 8th edition of Dana's Mineralogy states that Valentinite crystals are reported up to 2 cm. in length !!!!!), and a killer "thumbnail". It doesn't have the typical colorless or straw-color that the rest of the lot has, but it ranges in color from golden, to a deep brown. A great specimen of Valentinite !

Locality: Colavi mine, Cornelio Saavedra Province, Potosí Departament, Bolivia

Specimen Size: 2.4 x 2.2 x 1.4 cm.
