Aurichalcite crystals from Mina Ojuela, Mapimí, Mexico – 1 unique half size flat
This collection includes three visually striking specimens featuring the typical sky-blue to turquoise-green crystals of the secondary copper-zinc mineral Aurichalcite. The crystals appear as silky coatings, fine needles or matte crusts on contrasting matrix. The vivid color zones on reddish-brown to grey host rock give the set a particularly strong visual appeal.
The historic Mina Ojuela near Mapimí in the Mexican state of Durango is one of the world’s most important localities for secondary oxidation-zone minerals. In the upper levels of this former silver-zinc-lead deposit, numerous rare minerals formed through supergene alteration. Aurichalcite develops from the weathering of zinc- and copper-bearing primary minerals and typically crystallizes in radial aggregates or as needle-like coatings. The specimens presented here are representative examples of the rich color and structural diversity typical of this classic locality.
