Item Description

A very hard to find Brochantite specimen from the lesser-known Cerro Negro Mine in Atacama, Chile. The piece hosts radiating groups comprising acicular, pale blue-green colored, "needle"-like crystals of Brochantite on metallic matrix. The piece looks beautiful to the naked eye and just and lovely under magnification. I can see some tiny emerald green Dioptase crystals under the Brochantites for a nice touch! If you collect secondary ore minerals, or specimens from the Atacama Desert, don't miss out on this one! From the collection of Chester ("Chet") S. Lemanski Jr. of Browns Mills, New Jersey (https://www.mindat.org/user-461.html). Collection #23116CL. Chet was born 1947 in started collecting minerals circa 1957. He worked briefly as a drill runner at the famous Sterling Mine, in Ogdensburg, New Jersey and from 1987 to 1990 he helped convert the mine into a public access mining museum. He has held the role of treasurer, vice president and president of the Franklin-Ogdensburg Mineralogical Society (FOMS), and has been a board member and vice president of the Franklin Mineral Museum. The rare copper arsenate, Lemanskiite was named in his honor in 1999.
