Mellite is a rare aluminum organic compound found in a few lignite coal deposits worldwide. This is a translucent, wax-yellow, well-formed, tetragonal crystal with sharp beveled edges. This highly representative, seldom available rarity is from the Carl Davis Collection and Tula, Russia. NOTE: This is not from the more common mellite locality in Europe, which has produced more specimens for the market. This is much rarer.
