This mineral deposit in the mountains of Turkey remains the world’s only source of Zultanite. This exciting and relatively unknown gemstone is 100% natural with no heat, radiation, fillers or other enhancements. Zultanite, also known as Diaspore, is a colour change gemstone. In daylight, the gem is a beautiful kiwi to lime green. When moving to low inside or candlelight, Zultanite will slowly change from champagne to cinnamon, peach and sometimes an amber. Zultanite was named in honour of The Ottoman Sultans.
