The quality of Aurichalcite from the 79 mine, at Hayden, Banner District, Dripping Spring Mountains, Gila Co., Arizona is well-known and is indeed world-class, having first made waves in the 1960s and 1970s. Despite the fragility of individual crystal sprays the quality of this cabinet-sized specimen is excellent all round. It comes from the collection of the Very Reverend Michael Keirle, Dean of Jersey (no. MK/486), who obtained it during the 1990s, probably before a flood at the mine blocked access. His accompanying label records that it is from the famous 1960s-1970s find by Wendell Wilson. The bright turquoise-blue, feathery to acicular sprays of silky Aurichalcite are highlighted nicely against its pale grey matrix and white to colourless small bladed crystals of Hemimorphite. A really great sized display of this colourful and attractive secondary species whose crystal sprays look stunning under magnification.
