Turquoise is a stone that has been valued by humans for thousands of years. Native Americans appreciated this stone for its natural beauty and for its mythical power. It was used in ancient Egypt at least 3000 years ago. Important buildings in middle eastern cultures had domes and walls covered with turquoise. The Chinese, Greeks, Indians, and Turks all prized this pale blue stone.
Turquoise is formed as a secondary mineral. This means that the minerals (copper, phosphate, and aluminum) that make up the turquoise were part of another mineral or group of minerals before they came together in this form. It is found in arid climates often forming in cavities of volcanic rocks.
Color(s): blues, greens, blue green
Notable deposits of turquoise are found in Iran, Sinai, and the southwestern part of the United States.
