Gypsum, Atacamite, Quartz
Lily Mine (Lilly Mine), Pisco Umay, Ica Department, Peru
Cabinet, 11.9 x 7.0 x 4.4 cm
A beautiful and aesthetic cabinet plate from the 1998 find at the Lily Mine of Peru. Three sharp, transparent, wonderfully striated gypsum crystals to 2.5 cm are nicely set on very sparkly, drusy quartz-coated matrix. Tufts and individual crystals of green atacamite are richly strewn across the piece and some of the atacamite is included in the gypsum crystals. The primary, atacamite tuft-included gypsum crystal is indeed, striking. These were at first wrongly marketed as "brochantite inclusions in gypsum".
