Willemite with Chalcophanite, etc. (rare)

Item Description

Grayish-brown botyroids of uncommon Chalcophanite, hydrated Zn-Mn-oxide, to 9 mm, are attractively scattered on the contrasting undulating crust of spherical aggregates of lustrous, acicular, gray Willemite crystals. The willemite rests of the hefty, banded matrix of Hematite and Mn-oxides. The rich vuggy matrix on the back hosts a nice bonus of scintillating, glassy, colorless, tiny Hemimorphite crystals.
