The contribution of our service consists in digitalising an appraisal service of jewelry as well as precious stones by using artificial intelligence technology which allows us to rely on more than 250 criteria (material and immaterial) with monitoring more than 125 jewelry trends. Our expertise is carried out from both qualitative and quantitative database of more than 5 million pieces of jewelry from various origins, which makes it possible to assess newly produced jewelry, old jewelry, signed or not, as well as precious stones (synthetic diamonds and natural included): 25% of raw materials (rough gemstones and diamonds, metals at local market prices) / 50% of precious stones and diamonds from suppliers (including 12% of synthetic diamonds) / 25% of second hand jewelry. In order to carry out the appraisal and evaluation of the jewels included in your inventory, you just need to upload a photo and answer the online questionnaire. Our estimate will be made digitally and instantly, taking into account current market conditions. To make it easier, we have also set-up an automatic filling of your responses using GIA, HRD and Rapaport certificates. Build your digital jewelry securely, scalable and no download is needed!
