All the JEM creations are made in 18 carats ethical gold certified Fairmined. This gold, produced by human scaled artisanal mining communities, respects the most rigorous eco-responsible standards in terms of transparency and governance as well as environmental protection and social commitment.

It is in France, in one of the most renowned jewelry workshops located in the heart of the Vosges, that JEM jewelry takes shape. A workshop dedicated to the art of exceptional jewelry craftsmanship, committed to an innovative sustainable development policy, and offering the very best of its expertise to bring a new style of jewelry to life. Each piece is handcrafted using traditional techniques: it is this irreplaceable human expertise, perpetuated by exceptional artisans and passed down from master to apprentice, that is expressed in JEM’s creations.

Lab grown diamonds - or synthetic diamonds - do not come from the mine: man recreates in the laboratory the necessary conditions for their growth, then nature takes over, and it is at this moment that the magic happens: as in the heart of the Earth, the carbon crystallises, forming a rough and unique diamond.
