Should I get moissanite instead of a diamond to save money?
Obviously, I'm in the diamond business, so bear in mind that I have a bias here.
First of all, cost is a factor for EVERYONE. I've sold engagement rings for $2,000, and for $500,000, and every client I've ever had cared about the cost.
I really don't recommend moissanite, for a simple reason. It's an asterisk. Every time you our your wife tells people about her ring, the details will end with . As in "I love it, but it's not a diamond.*" There will always be an explanation that has to accompany the ring, and over time, that won't sit well with her, or with you. Perhaps you're thinking "my girlfriend isn't motivated by money, and she'll be proud of me for being frugal." And maybe that's true. But she'll be judged by friends, family, colleagues, etc., and so will you. Is that unfair? Yes. But it's the way of the world.
So, I would recommend staying within whatever budget makes you comfortable, but getting a natural diamond. Maybe it will be a bit smaller, maybe not perfect quality, but it will be free of *.
I hope this helps!
