Chrysoberyl is one of the most underrated gemstones in the market. Best known for two spectacular varieties: alexandrite, which changes color from green to red, and cat's eye, which displays a sharp line of light across the stone. Both are exceptionally rare. We source our chrysoberyls from partner mines in Sri Lanka, Brazil and East Africa. Direct, no middlemen. What makes these stones special? Hardness and durability rivaling sapphire, combined with optical phenomena you won't find in any other gem. Cat's eye effect should be sharp and centered, alexandrite should show a dramatic color shift. See what we have in stock below or tell us what you're looking for.
