Thumbnail, 2.9 x 1.6 x 0.8 cm
Monteponi Mine, Iglesias, Carbonia-Iglesias Province, Sardinia, Italy

A rare lead chloride carbonate related to Cerussite but much rarer, this crystal is sharp, ultra-gemmy, and has a mirror-like luster. The light amber color is very attractive, and the contact and possible fracture along the back does not detract from this remarkable crystal because it has 3 good sides! 2.9 x 1.6 x .8 cm
