St. Ives Consols, Cornwall, England
Miniature, 4.5 x 3.8 x 2.1 cm
Ex. Ed Ruggiero
This historical old specimen, once in the possession of Lord Tynes in 1876 (according to a probably mid-1900s attached label from a collector named D. Bury), is different than many St. Ives chalcosites I have seen; in that the lustrous, black, crystals are bladed, to 4.0 cm in length, rather than the standard, short or long prismatic crystals showing flat terminations. These look most unusual, and the result is more sparkle and flash than you normally see in a Cornish chalcocite. The luster is incredible, jhust brilliantly jet black is a stunning, slightly iridescent surface.
