Calcite on Aurichalcite
Ojuela Mine, Mapimi, Durango, Mexico
Small Cabinet, 6.0 x 5.2 x 3.7 cm
Emplaced on a limonite matrix are spherules of pastel blue aurichalcite, to .7 cm across. Aesthetically perched on the aurichalcite, are bladed, fan -like, crystals of glassy and gemmy, colorless, calcite, to nearly 3 cm across. Absolutely striking! This was an unusual habit in the pocket, and I had only a few good pieces.
