Sarkinite with Serpierite - Sold

Sarkinite is a manganese arsenate, dimorphous with eveite. Sjögren (1884) named sarkinite from the Greek "made of flesh", which certainly describes the color of the crystals here. The sarkinite crystals here reach 1.5 mm, in one place forming a 3 mm cluster. The bluish coating on the fracture surface is very fine grained serpierite (Dunn, 1995).

This specimen carries two collection labels, those of Rukin Jelks, and John E. MacDonald. MacDonald obtained the specimen from "R. Smith" in 1978.
