How To Sell GIA Diamonds

Selling a GIA Diamond is simple with WP Diamonds. Our team of GIA trained gemologists are industry veterans and expert diamond valuers. We will verify that the credentials of your certificate and simply confirm the authenticity of the stone vs the certificate. If your item is in excellent condition when we expertly value it, we will honor the amount that we have quoted to you over the phone or in email and pay you in full, without reservation.

We offer you an instant valuation of your diamond jewelry or loose stones based on the GIA grading report that accompanies your diamond item. For most Round Brilliant diamonds we make Instant Offers. We promise to pay you the exact amount quoted if the item arrives in excellent condition and is exactly the same item as stated on the certificate number you have quoted.

Our secure and streamlined diamond buying process takes as little as 24 hours.

What Is The GIA?

GIA is the world’s most respected gemological laboratory, entrusted with grading and identifying more gems than any other lab. Located in major gem and jewelry centers around the world, GIA laboratories are staffed by expert diamond graders and gemologists, whose work sets the standard for grading practices worldwide. 

The grading reports produced by the GIA are always very accurate and WP Diamonds places a significant amount of trust in the GIA reports. So much so that for all Round Brilliant stones with genuine reports, we can offer a specific dollar amount for your diamond item. For all other GIA certified diamonds we will provide you with a highly competitive price range based on the details of the certificate. Simply provide us with the cert number or a copy of the GIA report in order to receive an accurate price range.
