We are falling in love with Moissanite all over again. Not because it is a sturdy 9.5 hardness on the Mohs hardness scale, not because of it's lifetime warranty. Not because it is a socially responsible, eco friendly gemstone. But because of the magical prisms that catch the light and twinkle from every angle. 2.5x more the dispersion or 'fire' than a diamond, this gem is almost like the grown up sister to a rainbow moonstone. The dreamy rainbow sparkles look particularly good in large format and at a 1/4 of the price of a diamond you can sport this gem in big juicy pinterest/instagram worthy brilliant shapes.
