Peacock ore is Bornite and is an important source of copper. This ore is treated to bring out the irridescent colours. This piece has a dominant purple colour with a little deep blue, but no peacock colour. It is mounted on silver and comes with a leather cord, not a chain as shown in the image above. Chains can be supplied for an extra cost. The silver mount weighs 6 grams. The ore slice is 45mm long.
