Cassiterite, Wheal Maudlin, Lostwithiel (formerly in Lanlivery Parish), Cornwall, England

A superb twinned crystal of cassiterite. In Cornwall, cassiterite is concentrated in hydrothermal veins and pegmatites associated with granite intrusions. Cassiterite is the primary ore of tin, the most significant metal mined in Cornwall. This specimen measures 20mm x 25mm x 30mm

Copper with Quartz, South Caradon Mine, St Cleer, Cornwall, England

Copper with crystalline quartz. Most Cornish copper specimens are dull, but native copper (pure copper, uncombined with any other elements) from Caradon is invariably bright, as can be seen in this specimen. Copper lodes are widespread in Cornwall and, as a result, copper was one of the most significant metals mined in Cornwall
