Our Commitments
Honoring
French craftsmanship
Since our founding, we have chosen to handcraft every piece of jewelry in France. A rare commitment that few Maisons, even the most established, can genuinely claim today.
Our watches are made in a factory located in the heart of the Swiss Jura, the cradle of watchmaking.
Our jewelry workshops are certified by one, several or all of the following labels: "Responsible Jewellery Council", "Entreprise du Patrimoine Vivant",
"Joaillerie de France".
Our watches are certified "Swiss Made" by our Jura factory.

The House of
colored gemstones
Mastering precious gemstones is one of our greatest points of pride.
Blue-grey Sapphire, Cognac Diamond, Tsavorite... In addition to classic gemstones, we offer a selection of rare and unusual stones, usually reserved for high jewelry.
These stones are carefully selected to delight our eyes and stand the test of time.
Our colored stones are AAA quality, which means excellent brilliance, cut and color.
We offer a choice of diamond qualities: DIF, EVVS, GVS or HSI minimum. All are certified by the independent GIA (American) or HRD (Antwerp) laboratories as soon as they exceed 0.3 ct.

Responsible
Jewelry
Since its founding, Gemmyo has chosen to craft the vast majority of its jewelry to order. This approach eliminates unnecessary inventory and its inevitable impact on the final price, while further reducing the Maison's environmental footprint.
We work exclusively with diamond suppliers who adhere to the Kimberley Process, ensuring our diamonds are sourced responsibly.
Currently, there is no such standard for colored stones; however, our partners are selected on the basis of their reputations and must ensure that their products are as ethical as possible.
We have also decided not to buy back precious metals and to use recycled gold and platinum with purity levels of 75 to 100% to affirm our commitments with regard to environmental protection and the fight against corruption.
An object
for life
Gemmyo prides itself on creating objects that will last for one or more lifetimes.
Unlike other industries (such as fashion and technology), in which material waste has become a burning social issue, jewelry is a symbol of giving, of a meaningful object that can be passed down indefinitely.
In fact, we work in one of the very few sectors that have already been recycling for centuries: you don't throw away the materials that make up a jewel...they're too valuable! Gold, platinum, gemstones...everything is carefully recovered, re-polished, and refined.
