• Occurrence

  Turkey, Iran, Afghanistan, Eastern Australia, Tibet, Israel, Tanzania, Southwestern U.S.. Turquoise and zircon are the birthstones of the month of December.

• Appearance

  Sky blue to bluish green. The name means "Turkish stone". Turquoise is porous, so contact with liquids, oils or even perspiration should be avoided. Jewelry made with turquoise should be removed before washing hands, etc.. The pure blue color is rare, most stones contain the matrix from which it was found. Although the stones without matrix are rarer and more valuable, many people find the black matrix attractive, and makes the stone unique.

• Enhancements

  Turquoise is commonly impregnated with plastic, colorless oil or wax to improve color and increase durability. Untreated turquoise will eventually turn green.
