3.5 x 2.8 x 1.6 cm (1.4 x 1.1 x 0.6 inches)

The crystals are lustrous along the edges, whereas most of the broad faces are frosted. As is common for wulfenites below a few hundred dollars from this locality, a few crystals are incomplete.




8383:
Dioptase and Calcite
Arizona

Specimen status: Sold

A flat plate of matrix covered on both sides with a rich crust of brilliant, blue-green dioptase microcrystals. The dioptase is covered with a layer of colorless calcite, lending some sparkle. Another dealer's label which accompanies the specimen gives the locality as "Sunnyville, Arizona", but no such place exists. Probably from the Christmas Mine.
