Primary Malachite, Spinel-twinned Copper xls and Calcite on Copper (Mullane Coll.)

Item Description

Seldom do you see Bisbee combination specimens with this striking, sculptural quality and rarity. The matrix is a folded sheet of solid copper. Pretty green primary malachite microcrystals richly cover all sides of the copper matrix, including the STRIKING, free-standing, copper spinel-twins! The large spinel is 2.2 cm. And a super bonus are the "nests" of tiny calcite crystals, that look like eggs! This is a fabulous, old-time Bisbee combination specimen and is a real sleeper from the Dennis Mullane Bisbee Collection.
