RM1475   Danburite with chalcopyrite and bornite

San Bartolo Mine, Charcas, Mun. de Charcas, San Luis Potosí, Mexico

A huge size danburite specimen totally different from what we can usually find from this Mexican locality. Formed by a large group of prismatic crystals, which have different faces of the orthorhombic prism, with very defined terminal faces. Good transparency in most crystals, others are translucent. They are disposed on a matrix of good size chalcopyrite crystals, some of them partially covered by iridescent bornite. A museum piece.

Size: 10.0 x 9.0 x 4.0 cm.
Main crystal: 35 x 8 mm
