Chalcopyrite, Tetrahedrite, Quartz
Herodsfoot Mine (North Herodsfoot Mine), Lanreath, Menheniot Area, Liskeard District, Cornwall, England, UK
Miniature, 3.8 x 3.4 x 2.3 cm
A classic, old-time combination specimen from Cornwall, England. Lustrous, brassy, lightly iridescent chalcopyrite crystals to 1.1 cm with textbook, tetragonal form are richly and nicely scattered on the quartz matrix with charcoal-gray tetrahedrite crystals. Certainly over 100 years old in this quality. These are really sharp chalcopyrite crystals for Cornwall.
