Rainbow topaz is an inexpensive, elegant and trendy gemstone that has become one of today's most sought-after gems. Also known as mystic topaz, rainbow topaz is a natural topaz treated to show the desired rainbow effect. It makes for a unique piece of jewelry due to its multi-colored brilliance.

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.

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.

The most valuable is the pink to reddish topaz. This variety was found first in Russia. During that time it is only the Czar and his chosen people who are allowed to own it. Blue topaz is said to have healing powers to treat eye problems. The most common color is yellow with a red tint.

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.
