History of Turquoise

Turquoise is a blue to gray-green mineral consisting of copper aluminum phosphate. The mineral is a hyrous phosphate of aluminum, which includes a small percent of copper. The copper is what gives the mineral its blue coloring. When the turquoise mineral is associated with iron, thats when you get the greenish turquoise. If the mineral contains zinc, the turquoise mineral will be a yellowish color.

The Mineral Turquoise is formed by a chemical reaction which occurs when water containing specific minerals such as copper and aluminum leak through rock. It forms in veins, which later then turn into a clump of turquoise.

Turquoise deposits are found in Arizona, Colorado, New Mexico, California, Nevada, Virginia and Utah. The turquoise mineral is considered one of the highest value minerals in the world by most collectors. American Turquoise is valued by its matrix pattern, color, hardness and by origin. Turquoise made in the southwest is now know as one of the most valuable in the world.
