Heavy, dark gray, elongated crystals of native lead, to 2.5 cm across, make up this specimen from the venerable old Langban Mine. Native lead specimens are fairly rare in dealer stocks. This is a large piece with very large and easy to see crystals, especially for the price range. It is formerly in the collections of Phil Scalisi and Fred Geyl-Hansen. Mostly likely, it dates back 100 years or more
