- Paratellurite, Tellurium
- Miniature, 3.6 x 3.5 x 2.0 cm
- Moctezuma Mine (Bambolla Mine), Moctezuma, Mun. de Moctezuma, Sonora, Mexico
Paratellurite is a very rare species and this rich and showy ore specimen is from the Co-type Locality - the Moctezuma Mine of Sonora, Mexico. This gold-tellurium mine is renowned for its wealth of secondary tellurium minerals. Pastel-yellow microcrystals and crusts of paratellurite richly cover both sides of the quartz-rich matrix. A rich concentration of sparkly, silver-gray native tellurium microcrystals covers one end of this fine old-time piece from the Mullane Collection.
