i try to take a mental step back and remember that most of the people who see our jewelry will see a sparkly blur as our hands move, or maybe the occasional nice view of sparkle if our hands are at rest (restaurant, in line at checkout, etc) and without close scrutiny under proper lighting and sometimes magnification, nobody is really going to be able to tell (or, really, care) what sort of sparklies we're wearing.
even the "hand grabbers" mostly just want a better look at the design and/or sparkle and aren't always trying to figure out if it is "real"
...today i am happily wearing a rhinestone (not a CZ, i mean a vintage glass rhinestone) set in a rose gold plated ring. the last time i wore this ring out in public, i had a cashier tell me that this was the sparkliest diamond she'd ever seen.
