Bone, Copper minerals – Leogang (AUT)

This is an exceptional rarity; a part of an animal bone with it partly covered by secondary copper minerals. It is possibly the rest of a meal from the ancient miners, who left it there. Prehistoric mining was on copper; over time, copper minerals dissolved from the surrounding rock and were deposited on the bones. This causes the green color.

This is a unique piece that is very hard to find.
