Azurite - Sold

Azurite is a well known mineral, named for its azure color. At Tsumeb, many azurite crystals are thick, and while they may be transparent, they absorb so much light that they appear black. This example features seemingly black azurite crystals that show do a blue coloration under intense lighting. The varied crystal habit of azurite led Palache and Lewis (1927) to measure 170 azurite specimens from Tsumeb to clarify its crystallography.

This specimen dates to the 1970s. One prominent azurite crystal mesures 1.3 cm, and sits in a cluster of smaller crystals. Malachite and cerussite are also present, mostly on the opposite side of the matrix. From the Robert Chambers collection, a Tucson based collector. A good thumbnail specimen.
