Pyromorphite

Boy, what an incredible specimen this is. An initial generation of super bright wheat sheaf like crystals with a later generation of gem acicular sprays. A rind around part of the specimen indicates interference growth. Of the 9 Bunker Hill pieces that were in this collection this is by far my favorite. Top shelf miniature. Ex Ken Roberts collection.

Locality: Bunker Hill Mine, Kellogg, Shashone County, Idaho

Composition: lead chlorophosphate
