Item Description

A nice reference specimen of Brochantite on Malachite from the famous El Guanaco Mine in Chile. The display side of the specimen features attractive electric emerald green "needles" of Brochantite measuring up to a few mm sitting atop soft green colored Malachite on oxidized matrix. We have photographed the piece with a Canon MP-E 65 mm macro lens to better illustrate the quality. There are several little vugs on nearly every side of the piece which also host tiny but very attractive Brochantite crystals. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered.
