Orichalcum

Little is known about Orichalcum, the rare green metal occasionally (but rarely) found in ancient ruins. It is often mistaken for aged bronze, and is often only seen for what it is when one attempts to polish an object made from it. For when one attempts to polish it, one realizes that it is already as smooth and polished as any mirror, and the mottled green color comes from some inherent property of the alloy.
