Rainbow topaz, also known as mystic topaz, is a very elegant and trendy gemstone. It is a natural topaz that has been treated to display the desired rainbow effect. It is an inexpensive gemstone that makes for a unique piece of jewelry. Because of its unique multi-colored brilliance, it has become one of the most sought-after gems today.
Rainbow topaz is not a naturally occurring topaz, but is made from real topaz that is treated artificially with a thin film or coating to show the desired rainbow effect. This process is called vacuum deposition. Rainbow topaz is an enhanced treated colorless topaz with rainbow effect.
Typically, a thin layer of titanium or similar metal coating is applied to the stone’s pavilion, the underside angled portion that forms the bulk of the gem. This causes interference which results to various color effect of the rainbow. Natural refraction of the stone is altered by the coating, giving stunning rainbow colors. Rainbow topaz comes from pure topaz coated with ultra thin film similar to the ones used for camera films.
Topaz is a gemstone of all colors, though it is commonly thought of as just sky blue gem. Usually with tints of impurities, it has the colors wine yellow or straw yellow, pale gray, red, pink, blue, orange and brown in the stone. There are also different gentle tones available which range from yellow to yellow brown, pale to medium red, pink brown, orange brown, blue and translucent or transparent. Still, this depends on the impurities present on the gemstone.
Among these colors the most common is yellow with a red tint, while the most valuable is pink to reddish. The pink variety of topaz was first discovered in Russia, during which only the Czar and those he chose to give the jewel as a gift were allowed to own it. Blue Topaz is said to have healing powers. People believed that it can treat eye problems.
Topaz holds mystical powers that have been used for centuries. It was believed by Egyptians to dispel all enchantment and improve the eyesight of those who wear it. They also believed that the gem was colored with the golden glow of their sun god Ra, while ancient Romans associated topaz with Jupiter, the god of the sun.
