A three-stone zultanite ring This unique three-stone zultanite ring features three lab-created zultanite stones. The zultanite stone, also called diaspore, is one of the rarest stones on earth. And yes, these beautiful gems are always color-changing in different lighting! From a kiwi-like green under fluorescent lights to a champagne color in sunlight. Outdoors under clear skies, it looks pink with light yellow sparkle; indoors under traditional lighting, it turns to a kiwi green color; under candlelight, it emits an orange halo.
