Turquoise occurs in the whole range of hues from sky blue to gray-green, and is found in places where there is a high concentration of copper in the soil. The blue color is created by copper, the green by iron. Often, the deposits have veins running through it, which are brown, light gray or black. These depend on where it was found and the mineral deposits present in that area. They are known as 'turquoise matrix'. As a rule, turquoise occurs in veins or crevices, or in the form of nuggets.
The most well known deposits are in the USA, Mexico, Israel, Iran, Afghanistan and China. The most beautiful turquoises, in a splendid light blue, come from deposits in the north of Iran, and from the famous Sleeping Beauty mines in Arizona.
Turquoise, an ancient stone, continues to find itself in the fore-front of fashion. Its shining sky blue is one of the most popular trend colors in the world of jewelry.

The oldest evidence was found in Egypt, where grave furnishings with turquoise inlay were discovered, dating from approximately 3000 BC In the ancient Persian kingdom, the sky-blue gemstones were earlier worn round the neck or wrist as protection against unnatural death. If they changed color, the wearer was thought to have reason to fear the approach of doom.

The Indians of North America, who still produce a good deal of traditional silver jewelry with turquoises today, believe that the sky-blue gemstone opens up a direct connection between the sky and the sea.
