ID: CC13554
A quite magnificent specimen of Tetrahedrite with Chalcopyrite and Galena from Herodsfoot mine at Lanreath, Cornwall.  This large cabinet specimen has a matrix base of massive milky white Quartz veinstone whose top surface is covered with thick tabular pseudomorphs of Quartz after Baryte.  These are overgrown by well-developed crystals of dark grey Tetrahedrite many of which have a fine surface coating of golden brassy Chalcopyrite.  Partly coating and surrounding these are dozens of equant dark grey Galena crystals which form as modified cuboctahedrons.  A fine example which displays many of the mineralogical characteristics Herodsfoot mine is rightly famous for.
