D.NEA is a leader in lab-grown diamonds ever since they first became available in jewelry qualities. We put our full faith behind the diamonds we sell and are proud to offer the following policies:

Lifetime Trade-up

All D.NEA diamonds qualify for a lifetime trade-up. You may apply 100% of the original purchase price toward any diamond of greater value at any point in the future. This is an excellent solution for many of our customers if availability or their budget does not allow them to have their ideal diamond when they want it.

The original diamond must be returned and verified in original undamaged condition accompanied with its original certificate. If the certificate is not returned, there will be a $250 re-certification charge.

The trade-up applies to loose diamonds and does not include mountings or jewelry. We accept trade-in on mountings and jewelry, though they are evaluated on a case-by-case basis.



Best Price Guarantee

If you find a comparable lab-grown diamond for less, we will match or beat that price for your new purchase.

The diamond must be currently advertised as in-stock by a retail jeweler, and will be considered based on the four C's as well as other factors and conditions of sale, to determine its comparability.




The trade-up and best price policies apply for graded diamonds purchased directly from D.NEA.
