Rainbow topaz is an expensive gemstone that makes for a unique jewelry piece. It is a natural topaz treated to achieve the rainbow effect needed. It has become one of today’s most sought after gems, because of its multi colored brilliance. It is a very trendy and elegant gemstone also known as mystic topaz.

Rainbow topaz, also called mystic topaz, is an enhanced or treated colorless topaz with the rainbow effect. It is not a naturally occurring topaz, but it is made from a real topaz, which has been artificially treated with a thin film or coating to give the desired rainbow effect. This process is called vacuum deposition.

Rainbow topaz results from coating a pure topaz with an ultrathin film similar to the coatings used on camera films. Typically, a thin layer of titanium or similar metal is used. The coating is applied to the stone’s pavilion, the underside angled portion that typically forms the bulk of the gem. It creates interference effects, which results to rainbow effects of various colors. The stone’s natural refraction is altered by the coating, creating stunning rainbow colors.

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.

Ancient Romans associate topaz with Jupiter their son god Ra. For centuries topaz holds mystical powers. It was believed to improve the eyesight of the wearer and dispels all enchantments.
