Nimuzon is a marketplace. Browse the listings, open a gem you like and use the contact options on its page to enquire directly with the seller. Price, payment and delivery are agreed between you and the seller.

Many listings include a laboratory certificate. Check the details on each gem page, and see our Gem certification page to learn how to read a certificate.

Sellers can auction gems that our team has already approved. Open an auction to see the current bid, the closing time and how to place a bid.

Create a seller account from the Become a seller page and upload your verification documents. Our team reviews them, and you can list gems once your account is verified.

Each new listing uses one credit from a listing package. You can buy packages from your seller workspace. Unused credits expire after the period shown on the package, and we remind you before they do.

Every new listing is reviewed by our team before it goes live. You will get a notification as soon as it is approved or rejected.
