Moissanite Grades Explained: Color, Clarity & Cut
By Ryland, founder of Airwaves · Updated June 2026

"D-color, VVS, GRA certified" — moissanite listings are full of shorthand, and it actually matters. Here's what each grade means in plain English, so you can tell a genuinely good stone from a padded description.
Color: D is the top
Moissanite color uses the same D-to-Z scale as diamonds, where D is completely colorless and the letters climb toward faint yellow. D, E, and F are the colorless top tier. Every Airwaves stone is D — the best grade — so there's no warm tint pulling down the sparkle.
Clarity: how clean the stone is
Clarity measures tiny internal marks. VVS (very, very slightly included) means any inclusions are invisible to the naked eye — you'd need magnification to find them. Our stones are eye-clean, so what you see is pure fire, not flaws.

Cut: where the sparkle is made or lost
Cut is the one humans control, and it matters most. A well-cut stone bounces light back at your eye; a poorly cut one leaks it. Moissanite's high refractive index means a good cut absolutely blazes — which is why we care about proportions, not just carat weight.
Reading your GRA certificate
Your GRA report lists all of it — color (D), clarity, cut, carat, dimensions, and a unique report number. It's the paper trail that turns "trust me" into "here it is in writing," and it ships in the box with every moissanite piece.
Questions
What does D-color moissanite mean?
D is the top of the color scale — completely colorless, with no yellow or grey tint. It's the same top grade used for diamonds, and it's what every Airwaves moissanite is.
What clarity is good for moissanite?
Eye-clean is the goal — VVS or better, where any inclusions are invisible without magnification. Our stones are eye-clean so you see pure sparkle.
Does cut matter for moissanite?
A lot. Cut controls how much light the stone returns to your eye. A well-cut moissanite blazes thanks to its high refractive index, so proportions matter as much as size.
