Rosasite With Calcite
Ojuela Mine, Mapimi, Durango, Mexico
Cabinet, 10.0 x 6.0 x 6.8 cm
A stunning piece! It is smothered by thick rosasite on all sides but the back. An almost solid base of massive rosasite ultimately leads to a large central mound upon which velvety botryoids of richly colored blue-green rosasite are emplaced (to 2.0 cm across). The upper half of the specimen is liberally sprinkled with super-glassy and gemmy, colorless rhombohedra of calcite, to 1 cm across. The piece is perhaps the most 3-dimensional in the lot here, and in person is very dramatic and colorful. This is a very imposing and dramatic specimen, significant for the locality and even more, by worldwide standards for this normally rare species.
