Our expertise
40 years of expertise at your service
Experts in second-hand jewelry since 1985, when Véronique Devinaz founded Gemme in the heart of Lyon, Gemme masters every aspect of the gold and second-hand jewelry trades.
jewelry expertise has been the foundation of our work for 40 years. This visionary endeavour has been rewarded by our customers’ trust ever since.
Our team of a dozen advisors brings together all these skills in our two Lyon boutiques: gemmology, jewelry-making, history and styles, knowledge of precious metals and, of course, a unique trading experience, enabling us to determine the purchase and resale prices of second-hand gold jewelry with utmost rigor.
And we put this expertise to work for the benefit of our customers... and the future of the planet!
For all those who wish to sell their second-hand gold and jewelry, we can appraise it for free, and offer you the best market price, payable immediately.
For those looking for beautiful second-hand jewellery, Gemme offers you a choice of over 2,000 pre-owned jewels of all styles and periods, from the Napoleon III era to the present day, at prices 30 to 60% lower than new jewels.
In doing so, we are actively participating in a reasoned economy that consumes very little energy and raw materials, and it is essentially based on a 100% local loop.
Our second-hand 18-carat gold jewelry is all renovated in our own workshop or in Lyon-based workshops located just a few hundred metres from our boutiques.
The gold we collect and do not reuse is melted down by our Lyon based refiners, and eventually recycled into the manufacture of new jewelry.
