Q: Won't my Fiance Be Upset at Getting a Fake Diamond Engagement Ring? A: First of all, remember that moissanite is not a fake diamond, but rather a mineral that looks similar to diamond. You wouldn't call pink tourmaline "fake pink sapphire" would you? So think of it as a moissanite engagement ring, and lose the negativity. That said, buying an engagement ring is a very personal thing, and every couple has different priorities. Jewelers and the Wedding Industry have done a very good job of convincing all of us that we must have diamonds, so your fiancé may be disappointed. Why not propose without a ring, and then later discuss all of your options, and what you can afford? She may prefer having a tiny diamond ring to a large moissanite ring, or may love the idea of saving money on a gorgeous ring. If you really want to propose with a ring in hand, talk to her friends and family about the matter.
