Lily Mine, Pisco Umay, Ica Department, Peru
Small Cabinet, 6.2 x 3.1 x 2.0 cm

A matrix of chrysocolla and glassy, colorless quartz is the host for many lustrous, dark green clinoatacamite crystals to 1.1 cm in length. The largest atacamite crystal is also doubly terminated and TWINNED, it appears! This is a very rich specimen, and is in person much more sparkly and 3-dimensional than it appears. It has textbook crystal form.
