It is my understanding that Nexus is cubic zirconia.

If they won't tell you what it is, it's CZ.
If they say it's "synthetic diamond, but..." it's CZ.
If they say it's very special and much better than CZ, it's still CZ.
It's always CZ unless they tell you specifically what it actually is, chemically. And even then it might be CZ.
