Signed jewelry and watches
Our selection


Our mission
Born from the expertise of IGEM, Gemwheel combines scientific rigor with emotion.
Each piece of jewelry is evaluated, traced, and narrated. Each stone is carefully selected for its rarity, quality, or simply for what it has to say.
We believe in a more responsible, more sensitive, more sustainable jewelry. A jewelry that respects the past and inspires the future. A jewelry made to be passed down, transformed, and worn again.
At Gemwheel, each piece of jewelry has a story.
Our role is to reveal it — or to create a new one, with you.

Customer reviews
I had had a bracelet with stones in mind for a long time(...) The bracelet is of very good quality and I bought it feeling completely at ease, since the jewelry is appraised before sale and comes with a certificate. A great experience, I would recommend Gemwheel without hesitation.

For our engagement ring, we wanted something unique and we found the best team at Gemwheel. Sarah and Nathalie were incredibly patient, attentive, and very instructive. (...) A personalized, professional, and truly human experience. We recommend.
