What is Sierra Nevada Turquoise?

 The Otteson family owns several turquoise and variscite mines in central Nevada including the Sierra Nevada Turquoise mine. This nugget was mined and cut by them!

Turquoise is an opaque, blue-to-green mineral that is a hydrated phosphate of copper and aluminum. Turquoise deposits probably form in more than one way. However, a typical turquoise deposit begins with hydrothermal deposition of copper sulfides. This takes place when hydrothermal fluids leach copper from a host rock, which is typically an intrusion of calk-alkaline rock with a moderate to high silica content that is relatively oxidized. The copper is redeposited in more concentrated form as a copper porphyry in which veins of copper sulfide fill joints and fractures in the rock. Deposition takes place mostly in the potassic alteration zone, which is characterized by conversion of existing feldspar to potassium feldspar and deposition of quartz and micas at a temperature of 400–600 °C (752–1,112 °F)

This charm comes with a sterling silver (made in Italy) lobster clasp!

Clip to your favorite charm necklace, necklace chain, bag, bracelet, etc! The possibilities are endless.
