Rosasite With Calcite
Ojuela Mine, Mapimi, Durango, Mexico
Cabinet, 10.1 x 4.6 x 3.3 cm
Aesthetically nestled in a vug of solid limonite, this is a natural pocket cavity. Protected within is a layer of intense blue rosasite upon which are sparkling, glassy and gemmy, colorless, calcite crystals, to 6 mm across. Many calcites are actually included by rosasite, it seems. A few, tabular, white, 2-3 mm Baryte crystals are scattered on the calcite. The color and texture contrast between the limonite and the rosasite, and to the sparkling luster of the calcite, is vivid and mesmerizing. It really is "different." This piece is also admittedly priced at a premium for the result of this color and luster combination - really the most sparkly and visually stunning Ojuela rosasite specimen, overall, that I can recall seeing. Also, such an inclusion is extremely unusual at this mine or any other (most blue in calcites, is aurichalcite) .
