Learn the difference between real turquoise and imitation turquoise. Natural turquoise, an aggregate of copper aluminum phosphate hydrate, formed under heat and pressure, is often soft or porous when mined. The various colors found in turquoise result from the presence of either copper or iron--vivid blue is from copper and the softer green tones from iron. Turquoise stones can also have patterns of brown, yellow ochre and black matrix, produced from copper compounds. True turquoise has an opaque, waxy luster that may or may not include matrix, depending on the type of turquoise.

Understand that the gemstones used in almost all turquoise jewelry must be stabilized because natural turquoise is usually too soft to be worn as jewelry. The stabilization process of a turquoise stone involves submerging it into a stabilizing compound. This results in the natural action of the stones’ capillaries drawing the stabilizing compound into the gemstone.
