I have a 2 carat CZ ring that I wear sometimes and everyone thinks it's a real diamond

We were at a jewelry store getting DH's watch cleaned and they thought it was real too

I quickly let people know that it's a CZ when they comment on it, you never know someone's intentions.
Can't remember where I got it years ago, but it's the best $50 I ever spent. There is NOTHING wrong with using CZ's as a "placeholder" for your someday diamond. Good luck in your search
