This stone is really pretty and it is a real Moissanite. I tested it with a diamond tester that my friend uses in her jewelry business (Moissanite tests like diamond, but it is definitely Moissanite.). I got it from my ex and I am short on cash... haven’t worn it in a long time... it is really pretty. It flashes a whole spectrum of colors in the sun, even though the stone is dark green.
