A fine old, classic Pyro from the Sherman Mine in Burke, Idaho found long before the modern discoveries at the Bunker Hill mine. From the remarkable John Marshall Pyromorphite collection. Unlike other Idaho pyros, this has a distinctive color and habit that could pass for an early Pheonixville Pennslyvania piece! In excellent condition, the crystals reach 1 CM in size, filling a vug so densely the specimen is just about 100 percent pyromorphite with just a little matrix. Rare to see any of this material on the market and super rare in this quality! The last photo shows the crystallized backside of the specimen that is nice but not the better display side by far.
