Item Description

Algodonite is an uncommon copper-arsenide, and this impressive, old-time polished slab is composed of silvery-copper Algodonite. The solid Algodonite hosts about two dozen very attractive floral spherules of Prehnite. The largest of these is about 7 mm across. This is a quite rare combination piece, with no lack of aesthetics, and it is from a major mining region.
