Wherryite - Sold

Wherryite is a lead copper sulfate silicate mineral. Fahey et al. (1955) named the mineral in honor of Edgar Theodore Wherry (1885-1982), first editor of the American Mineralogist, and curator of mineralogy at the U. S. National Museum. Since the original material contained much cerussite admixture, a crystal structure solution by Cooper & Hawthorne (1994) showed that wherryite mineral contains essential silicate rather than carbonate. This specimen consists of massive linarite with cerussite and bright green wherryite. The wherryite mass is 14 by 6 mm.
