When an order is placed with authenticated shipping for an item containing precious stones, or when you are selling a piece of jewellery, it is entrusted to the care of our jewellery experts or gemologists.
In order to meet the buyer's expectations and avoid a potential cancellation of the sale, please include as much information as possible about any gems or items with a gemstone.
What to include in your listing
When creating your listing, the following information should be included. If you don’t know the information, please check your invoice or laboratory certificate.
Information on the precious metals used (eg. gold, white gold, platinum, silver etc.) and the specific names of the stones that make up the jewel;
- Good to know: The laws around jewellery and hallmarks can vary from country to country, and are designed to facilitate the cross-border trade of precious metal items and to protect buyers at the highest possible level. That’s why we ask that all jewellery items have a hallmark. If we receive an item at one of the Vestiaire Collective hubs to be checked, the item will be refused and returned to you if no hallmark is found
- The exact composition of the stones (For example, you should not state "crystal" if the item is "glass", or "stone" if it is "reconstituted stone");
- Include the laboratory certificate provided at the point of purchase if you have it. You can upload a photograph of the certificate as part of your listing, and will be expected to include the certificate with your item once it sells.
- Information about any treatments that have been applied to the gemstones;
- Information on the inclusions of natural gems.
💡 Good to know: When we talk about “inclusions” in gemstones, we are talking about any materials naturally trapped within a mineral as it forms. This could be crystals, gas bubbles, or even tiny fractures - all these are called “inclusions”.
A word on treatments
By law, a buyer must be informed of any treatment that has been performed on a stone (eg. oil or resin treatments, laser treatment, coating or irradiation).
If you’re not sure about the treatments your stone(s) may have undergone, we recommend having your gemstones appraised by a gemologist before listing your item on Vestiaire Collective. This will provide you with all the information you need to create a complete and accurate listing!
