Wheatley produced what were then considered among the world's great pyromorphite specimens, in the late 1800s (in fact, it produced much lead used during the Civil War in the US at the time). Wheatley pyromorphites were prized posessions in any American collection of the late 1800s and early 1900s, and few really good ones survive in private hands at the present time. This is an exceptional specimen with rich color that is a unique shade of dark green compared to prominent modern locales. It is very imposing, dramatic, and has large coverage. It is from the noted collection of John Marshall, longtime collector. Joe Budd Photos.
