We work with diamond professionals from around the world. Our auction sells your diamond to jewelers, brokers, polishers and retailers who usually only buy diamonds from in-industry sources.

By leveraging our unique relationship with these buyers you’re skipping many layers of middlemen and selling directly to the people who pay the most.

After creating your account at MyDiamondAuction.com you’ll use our pre-paid postage to send your diamond to our secure facility.

Once here, your diamond is graded, photographed, and recorded so that our bidders have all the information they need to place the highest bid on your stone.

We’ll then place your diamond in the next auction where hundreds of top-paying buyers bid to pay the most for it.

Once the auction has ended, we will notify you disclosing the highest bid. If you are unhappy with the final price you will have 24 hours to reject it and have your diamond returned at no cost to you.

If you’re happy with the final price you may accept it or do nothing and allow the system to automatically accept the bid.

After choosing your preferred payment method and providing any required information your payment will be processed within 3 business days.
