Diamond buy-back
Diamond buy-back specialist in Lyon
"Diamonds are a girl's best friend" sang Marilyn Monroe.
Thanks to its incredible properties of hardness and luminosity, it is used in jewelry to symbolise eternal love. We know it mainly in its colourless form, but it exists naturally in a wide variety of colours: pink, red and green diamonds are the rarest and therefore the most expensive in the world!
On the market, the price of a diamond is assessed on the basis of the 4Cs: Caratage, Clarity, Cut and Colour. These are the criteria that primarily determine the selling price of a second-hand diamond.
Depending on the condition of your diamond (wear, fluorescence, etc.), the existence of a certificate and its weight, we will offer you a purchase price based on the Rapaport. This professional reference gives the current value of your stone in relation to the diamond market. Gemme will therefore be in a position to make you a diamond purchase offer at the best price.
In strict compliance with the law, we offer immediate payment by cheque or within 48 hours by bank transfer. As soon as the sale of the diamond is completed, we will provide you with an invoice and a sales contract.
