Moissanite and the 4Cs
The diamond grading framework, applied to moissanite — and where it differs.
You have probably heard of the 4Cs — cut, colour, clarity, and carat — used to grade diamonds. They are a handy lens for moissanite too, with a few twists. Here is how each one applies.
Cut
Cut matters most for sparkle — a well-cut moissanite returns maximum light and fire. Quality of cut is worth prioritizing. See How to Choose a Moissanite Cut.
Colour
Like diamonds, moissanite is graded for how colourless it appears, with near-colourless stones most popular. Modern moissanite is typically very white. More in Moissanite Colour Grades Explained.
Clarity
Clarity describes tiny internal characteristics. Quality moissanite is typically eye-clean, meaning no inclusions are visible to the naked eye. See Moissanite Clarity Explained.
Carat — with a twist
Here moissanite differs: it is often sold by millimeter size rather than carat weight, because it is slightly lighter than diamond. The big advantage — its affordability means you can choose a larger size without the steep diamond price jump. See Moissanite Carat Sizes.
