Quartz ps. After Siderite or Pyrite (rare)

Item Description

Mineral specimens from this small, old Devon mine, worked intermittently from 1854-1923 are rarely on the market. This showy and unusual pseudomorph is very rare. The undulating quartz matrix hosts sharp glassy quartz points and unusual looking, quartz pseudomorphs after siderite or pyrite. Comes with a Nick Carruth label, well-known Cornwall-Devon dealer.
