  Turquoise is an opaque mineral that occurs in beautiful hues of blue, blue-green, and yellow-green. It has been treasured as a gemstone for thousands of years. Isolated from one another, the ancient people of Africa, Asia, South America and North America independently made turquoise one of their preferred materials for producing gemstones, inlay, and small sculptures.

Chemically, turquoise is a hydrous phosphate of copper and aluminum (CuAl₆(PO₄)₄(OH)₈·5H₂). Its only important use is in the manufacture of jewelry and ornamental objects. However, in that use it is extremely popular - so popular that the English language uses the word "turquoise" as the name of a blue-green color that matches the stone. Very few minerals have a color that is so well known, so characteristic and impressive that the name of the mineral becomes so commonly used. Only three other minerals -gold, silver, and copper - have a color that is used in common language more than turquoise.

Turquoise forms best in an arid climate, and that determines the geography of turquoise sources. Most of the world's turquoise rough is currently produced in the southwestern United States, China, Chile, Egypt, Iran, and Mexico.
