Mystic topaz is the result of a surface enhancement process that applies a thin metalite coating to colorless topaz, producing a shifting multi-color phenomenon - purple, green, teal, and gold moving across the stone's surface as light and viewing angle change. It is one of the few gemstone enhancement techniques that creates genuine beauty rather than simply imitating natural color. In a 10x8mm emerald cut, the step facets move across the surface slowly enough to reveal the color shift: different facets catch different wavelengths simultaneously, creating a stone that appears genuinely dynamic. The rhodium over sterling silver setting provides a neutral frame that does not compete with any particular color in the mystic topaz's range. At nearly half an inch, the color phenomenon registers at a meaningful scale. Available in sizes 5-10; not sizeable. A contemporary choice for the wearer who wants a stone that invites a second look.
