Senarmontite (rare,Type Locality) ex Ydren Coll.

Item Description

Senarmontite is an uncommon antimony oxide and this excellent thumbnail specimen is from the Type Locality in Algeria - the Djebel Haminate Mine. This is a sharp, waxy luster, translucent, gray senarmontite, floater octahedron. This is a rare species, and these old specimens were found by the old French exploration service BRGM, prior to the 1950s and even as far back as the 1850s. Odds are, that this was one of the specimens found on one of those French expeditions. You seldom see any examples of this species in crystalline form except from this locality. Complete all-around and nearly pristine, with only a bit of termination edgewear. Ex John Ydren Collection.
