Lab Grown Diamonds

There is absolutely no reason to buy diamonds that are mined from the earth.

Man made diamonds are lab grown. Like a diamond from the earth, they are pure carbon. And they are brilliant.

No longer are mined diamonds the only choice for engagement rings and fine jewelry. Eco/ethical concerns, coupled with technology advances, have made alternatives not just acceptable, but preferred. Our patented man made diamonds (sometimes also called lab-created or synthetic) are now, for all practical purposes, identical to mined diamonds in their physical and optical properties.

True Grown Diamonds are in every way identical to mined diamonds, except that they do not come from the earth. Lab grown and made of carbon, they have all the properties of mined diamonds – including flaws and grading – because they are in every way, diamonds. You can find them at in loose stones or in pre-set engagement rings.

Diamond Nexus offers Nexus Diamonds Alternatives

The patented Nexus Diamond Alternatives is unlike any other diamond alternative. It’s in a class by itself, and can’t really be compared to any other simulant. The Nexus Diamond is graded and rated just as mined diamonds are for cut, color and clarity; they are flawless and perfect in every way. They are extremely durable and cut glass as a mined diamond would. They are visually identical to the highest quality mined diamonds; an experienced jeweler with a loupe cannot tell them apart. And they’re guaranteed to be visually perfect forever. Nexus Diamonds cost approximately 70 - 90 percent less than mined diamonds.

Can you see the difference?

Seeing is believing and when I received my (ring from) Diamond Nexus, I was astounded in the quality, size and design.


I am thrilled with my DNL pieces, and will never buy the advertising hype, or the price tag of mined diamonds again!


It allows me to afford the look I want in a diamond. Moreover, why pay more when I can get something identical for less?


The earrings were as described and delivery was on time and well packaged. I was very satisfied and would purchase from them again.


My experience was awesome! Everything ran perfect. I will be shopping here again.
