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 examined, traced, and told. Each stone is carefully chosen for its rarity, quality, or simply for the story it has to tell.
We believe in jewelry that is more responsible, more sensitive, and more sustainable. Jewelry that respects the past and inspires the future. Jewelry made to be passed down, transformed, and worn again.
At Gemwheel, every piece of jewelry has a story.
Our role is to reveal it—or to create a new one, with you.

Your Gemwheel experience
You can drop off your jewelry at our premises or have it delivered. Gemwheel takes care of the rest (listing, jewelry description, authentication, photography, pricing advice to match the market, online sale)
Gemwheel connects sellers and buyers of second-hand jewelry, with independent gemological expertise. We do not buy the jewelry: we certify each piece before it is listed to ensure transparency, fair pricing, and trust for both parties.
Gemwheel offers a carefully selected range of second-hand jewelry, evaluated and certified by our gemologists IGEM.
We are not buyers: our role is to create a trust link between individuals wishing to sell their jewelry and buyers looking for authenticated pieces at a fair price.
Each piece of jewelry entrusted to Gemwheel is thoroughly examined, documented, and certified before being listed.
Our goal: to provide sellers with transparent showcasing, without excessive markups, and to allow buyers to access second-hand jewelry with complete peace of mind — backed by the guarantee of professional and independent expertise.
