Alexandrite is one of the world’s most enchanted gemstones for its phenomenal colour change from emerald green, blue-green or pale green in daylight to violet, ruby red or purplish red in incandescent light.

While Russia remains a limited source, Brazil and India are primary sources for Paul Wild, showcasing the magical optics of this gem in classic cuts in rare pairs and necklace layouts worthy of royal treatment.
