Tetrahedrite and Chalcopyrite on Quartz ps. after Baryte

A spectacular cabinet specimen displaying to perfection a true classic combination of minerals form Herodsfoot mine at Lanreath in the Liskeard District of Cornwall. Forming a flower-like structure of unfurled rose petals, crystalline milky Quartz forms large tabular pseudomorphs replacing former Baryte crystals, with each blade rimmed with a preferential coating of metallic grey Tetrahedrite dotted with the odd Chalcopyrite crystal. The dark Tetrahedrite edges to the individual Quartz pseudomorphs flawlessly delineate their structure, highlighting the shape of the replaced Baryte crystals. The Chalcopyrite has tarnished to an amazing and quite stunning spectrum of iridescent colours; from intense metallic maroon-purple to rich vibrant brassy-gold. It’s a superb specimen that will make a worthy addition to the best of Herodsfoot suites. The specimen comes with a Mike Brooke Collection label. This locality and its minerals are extensively researched and photographed by Roy Starkey in his Mineralogical Record article ‘The Herodsfoot mine, Lanreath, Cornwall, England’ (pp. 411-486, Vol 43, No. 4), now just approaching its ten anniversary of publication!
