The classic and Mexican Ojuela mine never ceases to amaze us. In this specimen we can enjoy a vug in the limonite matrix completely upholstered by aggregates of arsendescloizite crystals, with a slightly yellowish green color, on which numerous acicular aggregates of green malachite crystals have grown. On the label, they were described as conichalcite, but analysis indicates that it is this copper carbonate. Also accompanied and partially covered by calcite crystals, very transparent and bright, partially corroded naturally. A very aesthetic and unusual specimen for this mine.
