This specimen is an intergrowth of copper, malachite and cuprite. The copper takes on a dark, reddish-brown patina where it coats the copper. Uncoated copper has a fresh coloration. These darker colors are offset by rich green malachite overgrowth of copper. Although crystallization is at a minimum, the riot of colors makes this a beautiful specimen and it is significant for the locality as well

Excellent well-developed single crystal of Copper. The crystal has a fine luster and deep brownish-copper color. It is very unusual to find any copper crystal with this fine and sharp of a crystal habit, let alone in isolation. A truly fine specimen for any copper crystal, that happens to be a thumbnail size...rather than jus ta small copper

This is a unique specimen of intergrown copper and cuprite forming a large stalactite, with crystals of both seemingly intermixed but with cuprite the predominant mineral showing on the surface. The color is thus a deep red hue in good lighting, and it is much more attractive than appears in the photos. The piece is complete all around and 3-dimensional! It came out of the first collection of Dr. Ed David.
