A new vision of fine jewellery
Neither zircon nor crystal: a true diamond, simply of a different origin.
Pure carbon, identical crystal. Only the origin differs.
No eye, however trained, can tell them apart.
For equal quality and weight, about four times less than a mined stone.

What comes with every GMIR creation, far beyond the box.

Our story
GMIR is our founder’s family name. It comes from Qumayr, “little moon” in Arabic, born of Qamar, the moon. Light, brilliance, beauty: everything we hope to see you wear.
Thirty-five years between China, Paris and the workshops, for a single conviction, held since the very first day: to add value rather than artificially lower the price.
Read our storyThe departure. Beijing, then Shanghai: two years in China, then Paris Dauphine.
A first life in fine jewellery. Bespoke natural diamonds, from Paris to Antwerp.
Seven boutiques in Paris and one in Tunisia, under the Danish name FLEXA.
Lab-grown diamonds come to light. In November, GMIR Jewelry is born.
“A bigger stone is not necessarily more beautiful. What matters is the way it works with the light.”
