Our Diamond Nexus Labs Triple Guarantee is simply designed to provide you with an absolutely risk free shopping experience. You are protected three ways.
The Diamond Nexus Labs Money-Back Guarantee:
Inspect, enjoy, and wear your Diamond Nexus Labs jewelry for 30 days. If you are not thoroughly satisfied, even elated, your full merchandise purchase price will be quickly and cheerfully refunded.

The Diamond Nexus Labs Lifetime Performance Guarantee:
Diamond Nexus Gemstones have all the lifetime wearability of natural diamonds. A Diamond Nexus is forever. If any Diamond Nexus Labs gemstone ever fades, discolors, or becomes damaged, a free replacement will be granted.

The Diamond Nexus Labs Lifetime Gemstone Loss Guarantee:
If a Diamond Nexus Labs mounted gemstone is ever lost from its setting, we will replace it with only a nominal re-mounting charge. You do not need to cover your stone against loss with insurance.
Please Note:
1. Altering, re-sizing, repair, or resetting any Diamond Nexus Labs merchandise by anyone other than Diamond Nexus Labs voids the warranty and all guarantees. If you require a repair, stone setting, or re-sizing please contact us at 800.509.4990. We will be more than happy to assist you promptly and your guarantees will remain intact.
2. If you have purchased loose stones and are having them set by someone other than Diamond Nexus Labs, please tell your jeweler that the stones should be set as though they are rubies. The gemstones will not take direct heat. That said, we recommend having Diamond Nexus Labs set your stones in order to keep your warranty intact.
3. While we understand it may be difficult to choose the perfect piece of Diamond Nexus Labs jewelry, we can only allow four exchanges of any item of the same nature (the fourth would be non-returnable). If you would like assistance while shopping, please call our Customer Care representatives at 1-800-509-4990 or speak with one of our Live Chat agents.
