Independent Testing: Nexus Diamond Alternatives vs CZ
Nexus Diamonds are far superior to Cubic Zirconia.
Nexus Diamond alternatives and Cubic Zirconia are both considered diamond simulants—that is, stones that are made to look like diamonds, but are chemically different. That is where their similarities end, because Nexus Diamond alternatives are proven to have qualities much more like a diamond than CZ.
Nexus Diamond alternatives are harder, heavier and less porous than CZ, making Nexus Diamonds more durable, beautiful and lasting. This is proven by extensive tests in independent laboratories.
What it all means
That the Nexus Diamond alternative is harder, heavier and less porous than CZ means it is a superior stone. It is closer to the hardness and weight of a diamond, and will not absorb contaminants like dirt and oils from its surroundings, which can make a CZ look dull and clouded.
A Nexus Diamond will remain beautiful, forever. We are so confident of that, we guarantee our stones for life.
