Home > Mexico III Ojuela I – January 12 > MS1726 Duftite


Duftite is a hydrous copper lead arsenate first reported from Tsumeb (Pufahl, 1920). The mineral name honors Gustav Duft (1859-1924?), second General Manager of the Tsumeb Corporation mine. Claringbull (1951) first noted duftite at Ojuela, comparing and contrasting X-ray powder patterns of conichalcite and duftite. Duftite has a crystal structure similar to that of conichalcite but with higher symmetry.

Duftite here coats one side of a limestone fragment. In places colorless late rhombohedral calcite crystals have grown, providing a bit of sparkle to the piece. This specimen dates to a 2012 find. A rich and thick example for this find.
