Carminite with Azurite - Sold

Carminite is a lead iron arsenate, named for its carmine-red color (Sandberger, 1850). The Tintic district of Utah is well known for arsenates, and prior to the report fo Foshag (1937), collectors used the term "red olivenite" for carminite there.

This specimen of oxidized quartz-sulfide with a 2.0 by 1.8 cm cavity lined with red carminite, and later azurite microcrystals. A historic enamel label on the piece identifies the specimen as "red olvenite". A curious specimen of American mineralogical history.
