Unusual bundles of prismatic dark green prismatic Pyromorphite crystals to 10mm approx developed in limonite stained cavities in vein Quartz.   This form of Pyromorphite was restricted to one short section of the vein, discovered in the Driggith Mine opencasts in the late 1940's -early 1950's. Collecting from here is now restricted and this material is increasing scarce from the site.
