Arsendescloizite With Mimetite
San Juditas shaft, Ojuela Mine, Mapimi, Durango, Mexico
Cabinet, 12.0 x 8.5 x 4.0 cm
Ex. Martin Zinn
This large, rich specimen is surely one of the very best examples of its species from the small find, of about ten flats brought to Tucson in 1989. They were mined in 1988, according to the MR issue on the Ojuela Mine. Some pieces were sprinkled lightly with mimetite (much of it white), but this one has extraordinarily rich coverage of yellow mimetite and thus good contrast that is lacking in the few others I have even seen for sale over the years. The specimen in the University of Arizona Mineral Museum, illustrated in that issue of the MR, is 17 cm compared to the 12 cm size here, but it lacks the aesthetics and contrast of this piece to my eye. In any case, most have long since disappeared into museums and collections. I have seen only two great pieces, including this one, for sale in the last decade.
