NAC43XXX: Anglesite crystals on a Galena matrix from Shaft 5 of the La Cruz vein, one of the classic finds from the Linares mining district. The specimen is notable for its excellent luster and the abundance of well-developed crystals lining a small cavity in the Galena.
Specimens of this type are no longer found on the market, except for those originating from old discoveries such as this one, made by Antonio Álvarez around 1990.

Geologically, Anglesite is a secondary mineral formed by the alteration of Galena within the oxidation zone of the deposit. In the Linares-La Carolina mining district, hydrothermal lead veins hosted by Paleozoic rocks gave rise to some of the finest associations of secondary lead minerals found in Spain.
