1 in stock


This danburite is from Charcas, Mun. de Charcas, San Luis Potosi, Mexico. Mining of the ore bodies in this area began in 1583. The ore bodies contained sulfides of silver, lead and zinc along with other accessory minerals. One of the most famous of these minerals is the outstanding examples of danburite found there. They contain the elements Ca, B, Si, and O. This is a pair of parallel or tantric twin crystals with smaller crystals at the base. They have a blocky habit which is atypical for the usually chisel shaper crystals. There are minor calcite crystals present also. The crystals have a pastel pink color with a glass luster. They are mostly transparent with some internal flaws. This piece is a cabinet sized piece that measures 3 x 7/8 x 1 inches or 76 x 22 x 25 mm.
