Customer Service - Diamond Nexus

Lifetime Stone Guarantee

We are so confident in our patented technology and the heirloom quality of our Diamond Nexus™ alternative that we guarantee our stones for life! With normal wear and proper care, your Diamond Nexus alternative will not chip, crack, or discolor.

 

Sourcing only the finest quality Moissanite comes with its advantages! Rest assured your Moissanite stones will not only last a lifetime, but they will also maintain their superior brilliance, fire, and sparkle! Should any issue arise with your white or colored Moissanite gemstones, we’ll replace them for free. Forever.

 

We are proud to offer our customers the highest quality lab-grown diamonds on the market! Our lab-grown diamonds will perform identically to mined diamonds, and with proper care, will last many lifetimes. We highly recommend purchasing a protection plan through your preferred third-party partner to protect your lab diamonds and jewelry from accidental damage and loss. 

If your stones need repair, you may request a Return Merchandise Authorization for jeweler services.

 

Some limitations apply. Our lifetime stone guarantees do not cover, shipping, labor, such as setting the free replacement stone(s) into your jewelry piece or polishing and rhodium plating. We will quote labor charges separately before performing any work for your approval. Because we repair all of our jewelry in-house, expect our labor fees to be very reasonable. Guarantees do not include lost or missing stones or other color gemstones. Of course, we’re happy to replace a lost or missing stone or color gemstone at a reduced cost for both the stone(s) and labor. Any repair or service performed by a jeweler other than Diamond Nexus voids all stone guarantees. Warranty of jewelry metal and components are covered separately and described in the Free Lifetime Manufacturing Warranty section below.
