When an order is placed with authenticated shipping for an item containing precious stones, or when you are selling a piece of jewelry, it is entrusted to the care of our jewelry 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 jewelry 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 jewelry 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!
