You can see how this silky, translucent, botryoidal chalcedony has formed over a thick seam of banded malachite, in this large pocket that wraps around a central area where the chalcedony botryoids have joined to form a solid wall. The Miami (Arizona) area is known for its copper minerals, and this is an interesting and pretty association piece. Ex. Elling collection.
