A dramatic, L-shaped vug in quartz matrix is solidly lined with radial clusters of gemmy and lustrous, acicular, green olivenite crystals on this outstanding, old-time specimen from the Type Locality - Carharrack, Cornwall, England. Undoubtedly 100 years old or older, but no proof. An excellent provenance, having been in the John Barlow and Marty Zinn Collections.
