On a barite matrix are disposed several sharp pyromorphite crystals with a very interesting color zoning between olive-green in prism faces and yellow tones on terminal ones. Crystals show a hexagonal barrel-shaped prism with the pyramid terminal faces on the top. They have grow in divergent directions. Some of the crystals are isolated, with an elongated prism. Contrasting with the dark brown matrix. A classic between classics from this well known french mine closed in 1981. A great opportunity for pyromorphite and old classic mineral collectors.
