10 Year Trade-Up Guarantee on
Certified Diamond Purchases

When your 45-Day Money Back Guarantee has expired, you can still trade up your GIA or AGS certified diamond for one of greater value for the next 10 years! The trade up credit will be equal to the diamond's full purchase amount. There is no limit on the number of times you can upgrade your diamond and there is no restocking fee.

For example, if your original GIA or AGS certified diamond was purchased for $3,000 and you would like to upgrade to another GIA or AGS certified diamond that is priced at $4,500, you would only pay $1,500.

To trade up your diamond, please send us the diamond and original certificate, and you will receive credit for the price paid for your diamond applied towards a new diamond purchase. If the original grading report has been misplaced, there is a $250 re-grading charge. In some instances,a diamond may have incurred damage through daily wear. DiamondWave will accept the diamond back and deduct the cost of polishing and reshaping. Setting and applicable charges may apply on the trade-up.

If you have any questions, please call us at 1-866-978-7801, to speak with a DiamondWave service representative.
