How to Read a Moissanite GRA Card: Carats, Color & Clarity Explained

Buy a moissanite piece and it often arrives with a small certificate called a GRA card. It lists things like "D color," "VVS1," and a carat weight — but what do those actually mean? Here's how to read one.

What is a GRA card?

A GRA card is a grading report that comes packaged with many moissanite pieces. It describes a stone's specs: carat weight, color, clarity, cut, and dimensions. Think of it as a spec sheet — useful for knowing what you're getting, as long as you understand what each line means.

Carat weight

Carat is a measure of weight, not size — one carat equals 0.2 grams. On a fully-iced piece you'll often see a total carat weight that adds up every stone. A higher total carat weight generally means more coverage and more sparkle. Our moissanite watches list total carat weight so you know exactly how much ice you're getting.

Color (the D–Z scale)

Color is graded from D (completely colorless) down toward Z (a noticeable tint). D, E, and F are colorless and the most sought-after — they let the stone read icy-white. Most quality moissanite is graded D color, which is why it looks so clean under light.

Clarity (the VVS you keep seeing)

Clarity describes internal flaws, or "inclusions." The scale runs from Flawless down through VVS, VS, SI, and I. VVS — very, very slightly included — means any inclusions are microscopic and invisible to the eye. That's the sweet spot most iced-out buyers want: eye-clean at a fair price.

Cut

Cut is how well the stone is faceted, and it's what actually controls sparkle. A great cut sends light back at your eye as fire and brilliance. Terms like "H&A" (Hearts and Arrows) describe a precision cut with ideal symmetry. Cut matters more than almost any other spec for how a stone looks.

A quick reality check

A GRA card is a supplier spec sheet, not an independent appraisal from a lab like GIA. Treat it as a helpful description of what you're buying rather than a valuation. The stones themselves — their coverage, color, and fire — are what matter most, and those you can judge with your own eyes.
