Colorless translucent semi lustrous sharply formed crystals of hemimorphite measuring to 1.3 cm in length very nice and quite rich across the front of matrix. This is in great condition.

The Ojuela Mine, located in Mapimi, Durango, Mexico, was discovered by Spanish prospectors in 1598 and operated intermittently for over 350 years before closing commercially in 1932. Geologically, the deposit is hosted within deformed Cretaceous limestone units that have been intruded by Tertiary igneous rocks, creating an extensive hydrothermal pipe and vein system. Intense secondary oxidation processes acting on primary sulfide mineralization have produced a world-renowned zone of rich secondary mineral assemblages, making the mine famous for its exceptional variety of colorful arsenates, carbonates, and oxides.
