Adamantine is a jet-black alloy of adamant and other metals. Usually black in color, adamantine has a green sheen when viewed by candlelight or a purple-white sheen when viewed by magical light.
Adamant
This is the pure metal form of the hard, jet-black ferro-magnetic ore known as adamantite, from which the famous alloy adamantine is made. Adamant is rarely found in nature, but when it is, it is always in large spherical pockets in hardened volcanic flows. Adamant is one of the hardest substances known, but it is also brittle. A sword made of adamant could slice through most metals but would snap off if struck by another blade or even a smartly wielded wooden cudgel.
