A very rare piece for several reasons, including the color and the sharpness as well as the size for the locality. The diamond is completely opaque and black. It is a very large octahedral crystal, modified by the dodecahedron. It is 11 mm on edge or larger measured across, about 1.5 cm. 23.95 cts: 15 x 15 x 15 mm This Photo was Mindat.org Photo of the Day - 20th Jul 2006
