Diamond Simulants

Today’s simulants share many of the same captivating properties as diamonds.

A “diamond simulant” is a stone that appears to be a diamond, but is chemically distinct. Diamond simulants have been available for years, but modern technology has only recently created stones that are much closer to diamonds.

The Nexus Diamond™ alternative is the world’s first heirloom quality diamond simulant. It is superior to diamonds mined from the earth and all other simulants.

Simulates the look, weight and wear of a diamond.

Even a jeweler with a loupe cannot tell the difference between a perfect diamond and a Nexus Diamond.

Perfect cut, color and clarity

Lab conditions allow us to create perfect stones. Completely colorless (D color), internally flawless (IF rated) and Ideal Cut for maximum brilliance.

Certified by the AIG (American International Gemologists)

Nexus Diamonds are graded the same as diamonds and you will receive all certifications with your purchase.

Same beauty, sane budget.

The average American engagement ring costs thousands of dollars. There’s no need for that. Nexus Diamonds cost up to 80% less than mined diamonds.

No sacrifices.

Because our stones are perfect and our jewelry is handmade in the U.S.A., there is no need to sacrifice quality to achieve the look you want.

Guaranteed, forever.

Our Lifetime Stone Guarantee ensures the Nexus Diamond will never chip, crack or discolor. If something does happen, we'll replace it for free, forever.

Mind your stone. Know the differences between diamonds and lab created diamond simulants.
