Looking for the very best alternative to a diamond?

You want a man made stone that looks, feels, and acts like a diamond, but is also affordable, eco-friendly, and conflict-free. When considering a man made alternative to a mined diamond, there are three qualities to consider:

Diamond Nexus Qualities There are several types of stones that attempt to match these characteristics, to varying degrees:
Typical Diamond Simulant
This covers your basic cubic zirconia (CZ) or Moissanite: man made stones that try to look like mined diamonds, but don’t have the same chemistry or durability. They range from very cheap to mid-level prices. CZ is by far the most common, but it has two major problems. First, it’s more porous than a mined diamond, meaning it’ll absorb dirt and oils from its environment and over time, this will cause it to turn foggy. Second, it’s not as hard, so it’s prone to breaking. Moissanite is tougher, but refracts light differently. Some people feel that this gives the stone away when compared with a diamond.
Diamond Nexus Simulant
These unique patent-pending man made stones share the same durability, brilliance, and fire of mined diamonds. Not just any mined diamonds, but top grade D colorless mined diamonds with IF clarity: the highest quality mined diamonds in the world. The only difference between a Diamond Simulant and a mined-diamond is the chemical makeup. Our Diamond Simulants are the perfect choice costing 90% less than a mined-diamond without sacrificing an ounce of beauty.
Our stones are guaranteed to last a lifetime, have been selected by the Miss Universe Organization to be used in her eco-friendly crown, and do not cost an arm and a leg. Over 200,000 of our customers are smart enough to realize that it’s not the chemistry of their stone that really matters, but the chemistry between two people. They chose Diamond Nexus and never looked back. Thanks to them:
