Cymophane or Cats eye? on Sep 3 2006, at 09:58 in Cymophane or Cats eye?
Hello,

I know of at least 7 terms used to call an opalescent variety of chrysoberyl, which are: Chrysoberyl Cat's-eye, Cymophane, Cymophanit, Cymophanita, Cymophanite, Cats eye and Cat's eye.

Which one should I used, why and where?

Thanks
Chris
