A beautifully crystallised thumbnail specimen of Chalcocite from Levant mine at Trewellard near St Just, Cornwall, England. The entire specimen comprises of well crystallised Chalcocite although the two smaller groups of crystals form a natural base from which a larger, 1.4 cm tall thick-set crystal stands close to vertical. The crystals display vertically ribbed and striated prism faces and almost faces have an almost sooty black coating so dulling the metallic lustre, a characteristic well known for Chalcocite from this part of Cornwall.
