RM2468   Calcite

Santa Eulalia, Aquiles Serdán, Chihuahua, Mexico

RM2164   Mimetite with calcite

Santa Eulalia, Aquiles Serdán, Chihuahua, Mexico

Mimetite Mexican specimens from Ojuela mine (Durango) and Potosí mine (Chihuahua) are the best considered by collectors. Currently those of Ojuela abound, but those of Potosí, with isolated crystals and globular aggregates like this specimen, are more rare to see. They stand out for their intense yellow-green color in some area and on a matrix of rhombohedral crystals of calcite.


Size: 5.6 x 4.7 x 2.3 cm.

They present a slightly pinkish tone due to the presence of Mn. Extremely fluorescent under LW-UV, with a spectacular pink to red color. They are accompanied by small octahedral cubic crystals of colorless and transparent fluorite. In a matrix of bright crystals of pyrite, sphalerite and galena. An exceptional piece.
