All JEM creations are crafted from Fairmined-certified 18-karat ethical gold. This gold, produced by small-scale artisanal mining communities, meets the most rigorous eco-responsible standards in terms of transparency, governance, environmental protection, and social commitment. Fairmined contributes to local economic development, helps combat poverty and corruption (money laundering, financing of armed conflicts), and reduces the harmful impacts caused by unregulated artisanal mining.

It is in France, in one of the most renowned jewelry workshops located in the heart of the Vosges, that JEM jewelry takes shape. This workshop is dedicated to the art of exceptional jewelry craftsmanship; it is committed to an innovative sustainable development policy and offers 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. Like a fire lit, or a cultivated flower, this new diamond is the result of these magical unions, both random and controlled, of the impulse of Man helping Nature to give birth to what she already owns.
