    As far as gem mineral, a curious crystal called alternately red beryl, red emerald, or bixbite. Apparently only one mine has been found and the amounts of deposits were not even that great. For more information check the link below.

    Probably Painite. There are only 19 known specimens of Painite. Taafeite and red diamonds also rank highly in the most rare category. There are only about a half cup of Taafeite known in all the world and fewer than 40 red diamonds in known existence.
