With as much detail as possible.


One of our consultants will contact you shortly (by phone or email – your choice) to discuss your item and the Diamond Whisperer process. We will then give you an initial price range and discuss next steps.


To receive your final price, our experts will need to see the item in person. Here, you have two options:

We can email you a pre-paid and fully insured FedEx label, so that you can ship the diamond jewelry or luxury watch to our New York headquarters. We receive your items the next day and get back to you usually within 24 hours.

Alternatively, you can bring in your diamond jewelry or luxury watch to our New York headquarters and meet with our experts who will provide you with an offer there and then. You can leave our office with your money!


If you choose to send in your item, we will provide you with a final price and wire the money into your account the same day or send a check. Should you choose not to move forward with our offer, we will return your item free of charge and fully insured, no questions asked.

We have bought tens of thousands of carats and ensure both a reliable and trustworthy service. Contact Diamond Whisperer today if you have any queries about selling your diamonds online. We will be happy to answer any questions you may have.
