Bournonite with Quartz, Herodsfoot Mine, Lanreath, Cornwall, England

Steel-grey twinned bournonite crystals, in distinctive cog wheel formation, with colourless quartz. This fine specimen from the lead and silver mine, Herodsfoot, may have been acquired by the Royal Institution of Cornwall as part of a group of specimens purchased from Richard Talling, the great Cornish mineral dealer, for £8.10s in December 1858. Bournonite, a rare sulphide of copper, lead and antimony, was first described in 1797 by Philip Rashleigh of Menabilly in Cornwall, who included illustrated descriptions of two specimens in his publication Specimens of British Minerals, Selected from the Cabinet of Philip Rashleigh. The specimens described by Rashleigh came from Wheal Boys, an antimony mine in St Endellion parish and the type locality for bournonite
