Description: Duftite-conichalcite series Ojuela Mine, Mapimi, Durango, Mexico 4.5 x 6.5 cm. Light green botryoidal and micro-crystals associated with colorless calcite crystals on the typical gossan matrix. I acquired this piece from Jordi, and he indicated that the 3 pieces that he had tested each turned out to be duftite.
