Prehnite

Item Description

The Goboboseb Mountains in the Erongo Region of Namibia have been producing some excellent mineral specimens for a couple decades, including some of the best quality and most striking examples of Prehnite from any contemporary discovery. This piece features attractive, somewhat spherical, layered groups of eye-catching green Prehnite measuring up to 2.3 cm across, sitting on white Calcite on volcanic rock matrix. There is decent translucency in the Prehnite groups when backlit, and they are for the most part, damage free, save the periphery where the piece was removed from the pocket wall. From the collection of Chester ("Chet") S. Lemanski Jr. of Browns Mills, New Jersey (https://www.mindat.org/user-461.html). Collection #19486CL. 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.
