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.

Stone is a yellow shade, much like treated citrine. There was no color change under any light as advertised (similar to andalusite). I reached out and was told all stones were different. I know crystals and gemstones, and as I suspected this was a social media scam to get sales.
Hi Lori, we are truly sorry to hear you feel this way and we want to address this openly and honestly for everyone reading.
We are not scammers. WOMUSE is a brand built on authenticity, craftsmanship and a genuine love for rare and beautiful stones. We have a community of women around the world who wear and cherish their pieces every single day and that means everything to us.
Regarding your stone… Zultanite is one of the most extraordinary colour shifting stones in the world, presenting in kiwi green, champagne, cognac, golden yellow and soft blush pink all within the same stone depending entirely on the light it is under. This is not a flaw, it is the magic. The colour shift requires cool fluorescent lighting specifically and without that the transformation simply will not be visible regardless of how experienced you are with gemstones.
We did reach out to you personally via email to help you experience this for yourself and unfortunately we have not heard back from you. Our offer to assist you still stands.
That said, we are not here for transactions. We are here for women who connect with our values, our story and our mission. If this piece does not feel right for you, we would genuinely welcome you to return it. Every woman who wears WOMUSE is a reflection of what we stand for and we would never want anyone wearing our pieces feeling anything less than proud.
Please do reach out to us at support@womuse.com and we will take care of you.
With love, Jenny x
super thin appears very cheap does not take returns
Beautiful!
Hermoso
This is a pretty stone and setting. The color doesn’t change as much as I hoped though.
The heart ting appears to be made of quality materials. In more natural light it stays a pretty gold. In artificial light it will turn green before your very eyes.
