How It Works

Buyer Seller

01. Go to the Diamond Marketplace store and browse hundreds of pre-owned diamonds. You can search for a specific type of diamond or look through the entire selection

02. Found the perfect diamond? Create an account. From there you can set a bid for the diamond or purchase directly.

03. Your diamond will then be authenticated by our experts. We can also set your diamond into jewellery if desired. We then ship the diamond directly to you.

01. Go to the Diamond Marketplace and receive an instant valuation for the diamond you wish to sell. No GIA number? No worries, we can still offer a valuation within a few working days.

02. If satisfied with your valuation, set up your seller account and store homepage. You can now receive bids and direct offers from buyers.

03. Once you agree on a proposed price from a buyer, you close the bidding and sell your diamond. Your diamond will then be authenticated by our experts. Finally, ship the diamond to the buyer and the sale is complete.

A Diamond Marketplace For The 21st Century

Diamond Marketplace was born out of a desire to provide a safe, secure and open C2C platform for buying and selling diamonds online. The brainchild of Ryder Diamonds and BarbiDiam, Diamond Marketplace seeks to disrupt the current market by addressing all the challenges modern-day diamond sellers and buyers face regularly.
