Some stones are beautiful.
This one is alive.
At the centre of this ring sits an 8mm heart-cut Zultanite... one of the rarest gemstones on earth, found in a single valley in the mountains of Anatolia, Turkey, and nowhere else.
What makes it extraordinary isn't just where it comes from.
It's what it does.
Under cool fluorescent light, it glows a vivid Kiwi Green... bold, alive, unmistakable. Move into warm incandescent light and watch it soften into Champagne Yellow... quiet and luminous, like last light on gold. Step into sunlight or candlelight and something rare appears... a delicate, shimmering Lychee Pink that most women have never seen in a stone before.
Three colours. One ring. One woman.
It shifts the way she does... composed in one light, warm in another, luminous in the next. Never the same twice. Always entirely herself.
(Please note: the stone’s colour may vary under different light conditions.)
Custom sizes and Natural Stones are available upon request. Please contact our support team if you need a different size.
