Botryoidal Native Copper (rare style) Mullane Coll.

Item Description

A very rare and sculptural large native copper from the famous mines at Bisbee. Massive botryoidal copper, such as this, is extremely rare. The striking amoeboid-looking piece is composed of several generations of hackly copper. One side is enriched with copper with a fine, bright patina. Interestingly, the edge-on view shows that the botryoids are layered. Ex Dennis Mullane Bisbee Collection. Valued at $1000 for rarity and quality.
