Chalcophyllite, Olivenite
Carharrack, Gwennap area, Camborne - Redruth - St Day District, Cornwall, England, UK
Small Cabinet, 5.4 x 4.4 x 4.0 cm
Lustrous, emerald-green to turquoise-blue chalcophyllite plates richly cover the vuggy, quartz-rich matrix on this fine, old-time specimen from the famous mines of Cornwall, England. A portion of the vug is lined with dark green olivenite microcrystals. Classic material from this renowned locale. Ex. Jean Behier Collection, a well-known French exploration geologist and collector of the mid-1900s. Certainly this would have been most likely to come out in the heyday of the mines here, and is likely over 100 years old, but no proof. In any case, it's an excellent example similar to the historic material from here you see in old books.
