History

This colorful beauty begins with a natural topaz gemstone that is millions of years old. Modern technology makes it even more beautiful and desirable with a process that deposits a thin film onto part of the surface of a white topaz gem. This creates an eye-catching rainbow effect as light passes through the stone. The result is a dazzling kaleidoscope of colors. The result is Mystic Topaz®. The result is... almost magical!

Care

The coating that gives this stone its rainbow should not be re-polished, scratched, or chipped. Gentle rinsing in warm water should be all you need to keep it bright. Keep your Mystic Topaz® free of perfumes, lotions, and chemicals.
