What our sellers say

★★★★★
“Excellent service. Contacted Mozeris and corresponded with Faustas. Responded immediately to my email to sell a 20g gold bar and a half sovereign coin. Received an offer and after a few further email exchanges to finalise, I posted with special delivery and was paid out shortly after they received the items.”

“I was apprehensive about selling my mother's omega watch but the whole process was straightforward and reassuring. Faustas was extremely helpful and understanding and the communication was very quick. The money agreed was in my account within hours of accepting an offer.”

Questions

Questions about selling diamond necklaces

Do I need a certificate to sell a diamond necklace?

No. We assess the stones ourselves. If you have a laboratory report or a valuation, include a photograph.

Do you buy old-cut diamonds?

Yes. Old mine and old European cut diamonds in antique necklaces are bought and are valued as part of the piece.

How do I send it to you?

Book a free insured FedEx collection from your door, or post it by Royal Mail Special Delivery and we refund the postage. Both are tracked and insured to £10,000. You can also see us by appointment in Mayfair or Braintree.

When am I paid?

By bank transfer the same day we inspect your items and you accept our offer. If you decide not to sell, everything comes back insured, at our cost.
