- Aurichalcite, Rosasite

- Ojuela Mine, Mapimi, Mun. de Mapimi, Durango, Mexico
A remarkable, richly crystallized cabinet aurichalcite specimen from the Mina Ojuela of Mexico. Radiating clusters of glassy, beautiful turquoise-blue aurichalcite needles fill the sculptural, vuggy, limonite matrix. Green rosasite coats some of the aurichalcite on the upper-left and lower-right side fringe. An added bonus is more aurichalcite in a vug on the side of this outstanding old-time specimen. The Scott Williams label with the piece indicates the piece was acquired in February, 1960. As stated in the aurichalcite section, pp. 55-56 of the Mineralogical Record Mexico Special Issue II, Vol 34, No. 5, Sept.-Oct., 2003: "Aurichalcite in beautiful specimens is one of the signature minerals of the Ojuela Mine."; and "No aurichalcite specimens remotely comparable to these early ones (1950s and 60s) have been found in the Ojuela mine since the mid-1960s; it is a rare mineral on the market today."
