Peace of mind for your piece of jewelry.

We stand behind the Nexus Diamond™ alternative. In our Milwaukee, Wisconsin, workshop we set our alternative stones by hand—never machine stamped—laboring over each detail, and every ring is inspected individually. Nexus Diamond alternatives are guaranteed gorgeous for generations.

Our Lifetime Stone Guarantee ensures the quality of every stone. Forever.

Nexus Diamond alternatives should not chip, crack, or become discolored or cloudy with normal wear. We guarantee it. And if something does happen to your stone, let us know and we’ll replace it for free. Yes, forever.

All Diamond Nexus pieces include our Everything’s Covered Plan for one year from your purchase date. This includes all metal repairs, plus periodic cleaning, polishing and inspections – including shipping both ways.*

We always recommend insurance coverage for your engagement ring or large fine jewelry purchases in case they’re lost or stolen. We can refer you to reputable jewelry insurers; just give us a call.
