Why do I need to send my diamond ring to you?

In order for buyers to bid with confidence, they need to know that every ring is authenticated and that the selling description is guaranteed. That is how we get buyers to bid for the full value of the diamond ring. Furthermore, a large part of the work that we conduct on your behalf is done while in our possession such as the high resolution photography, buyer targeting, and final transaction. It is crucial that we are able to physically see your ring and assure that it is going to the right people at the right price.

If I reject the offer will you send back my diamond ring?

Yes. If you are not satisfied with the offer and it falls below the agreed reserve price, simply request for the diamond ring to be sent back to you. We will immediately send your diamond ring back in the same condition it was sent to us, no strings attached. However, once you agree to a reserve price, you are committed to selling your ring.

Why should I trust your grading partners over my local jeweler’s appraisal?

Buyers place higher bids with Martazon because we only use the very best in the industry to authenticate and grade ring auctioned with us. Our grading partners include the Gemological Institute of America, the International Gemological Institute and the reputable professionals at CentralWatch. Gradings carried out by our partners are so thorough and trusted in the industry, that we put forth a description guarantee. Buyers that come to Martazon know that what they see is what they get, and ultimately place higher bids.
