My diamond ring has rainbow fire. Perhaps moissanite has even more of it? I also read that it’s a major difference but I’ve never seen a moissanite irl. I find my white sapphire ring mostly has white flashes, but my diamonds have tons of rainbow colour.

My diamonds have a ton of rainbow reflection especially under store lights and right after it’s cleaned!

I saw a moissanite and it seemed that the little rainbows were contained within the stone itself.  I have a diamond on my ering, and I noticed that it gives mostly white flashes, and blue and green.  If I get it in the sun while in the car, I see that it gives off little rainbow reflections on the roof of my car. 🙂  I didn’t have the opportunity to try that with the moissanite, but would have liked to!

My diamond is very colourful and rainbowy outside and in shopping mall lighting. Indoors, more white. It’s a D coloured, excellent cut, VS1, no fluorescence diamond.

@FR825:  Do you have a side shot of your diamond?  That should make it easier to tell if it’s cut like a diamond or like a moissanite.  If you’re really worried, I’d take it to a jeweler though.  They’d be able to set your mind at ease better than we can.

Someone said that the rainbow colors in moissanite make it look like “clear opal”. My diamond has lots of rainbow sparkles (fire) under certain indoor lighting, but I can tell the stone itself is colorless. Does your diamond have any fluorescence?
