yup cz has been a mainstay for a long time.
I did jewelry professionally a few decades back and now just dabble with beaded fun stuff... but When I personally lost a small diamond out of “whatever” I had my friend who would replace with cz.
Not sure how this new thing compares to CZ. CZ is quite beautiful
OH BTW ,, i love Pandora. Wore my bracelet yesterday. Each bead/charm very meaningful.. Yes I have knock off bracelets but my genuine Pandora is my fav.
