A large specimen of silvery, massive Guettardite and probably contains some Zinkenite. It is encased in Siderite. Hampson collected this specimen in 1977. Specimens of Guettardite are rarely seen on the market. This is an exceptional specimen. It is an ore of lead, but since it is a rare mineral, it cannot be regarded as an important source of lead.
