Wherryite with Diaboleite - Sold

Wherryite is a lead copper sulfate silicate. Fahey et al. (1955) named the mineral after Edgar Theodore Wherry (1885-1982), curator of mineralogy at the Smithsonian Institution. Since the type material contained admixed cerussite, a crystal structure solution by Cooper & Hawthorne (1994) showed that wherryite contains essential silicate rather than carbonate.

This specimen consists of quartz matrix with crystalline blue diaboleite and pastel green wherryite. The wherryite is very fine-grained in this example, which explains its pale color.
