This matrix is heavily invested with massive crocoite, but a protected vug in the center has several prismatic, lustrous and gemmy, reddish- orange, crystals to 1.5 cm in length. Surrounding the vug and then running in veins throughout are rich veins and surface carpets of olive green vauqelinite, a rare lead-copper species. Over two hundred years ago, crocoite was first described from this locality. At that time, Vauquelinite was found in some quantity but it has not, to my knowledge, been found in any recent reworkings of the locality. 8.8 x 5.8 x 3.8 cm
