GRA Certification

Understanding Your Gemstone Documentation

Every moissanite stone above one carat in your jewelry comes with independent certification from the Gemological Research Association (GRA). This documentation provides verified details about your gemstone's characteristics, giving you confidence in what you're purchasing.

WHAT IS GRA?

The Gemological Research Association is an organization that provides standardized grading and certification for moissanite gemstones. Each stone undergoes laboratory analysis to evaluate its quality characteristics, and the results are documented in an official report.

The certificate serves as a detailed specification sheet that confirms your stone's properties—color, clarity, cut quality, and precise measurements.

WHAT YOUR CERTIFICATE INCLUDES

Stone Identification

Your certificate confirms the gemstone as genuine moissanite (silicon carbide), distinguishing it from other materials like cubic zirconia or glass.

The Four C's

Color Grade

Moissanite color is graded on a scale from D (completely colorless) to K (faint color):

Grade	Description
D, E, F	Colorless—no visible tint
G, H, I	Near colorless—slight warmth visible under close inspection
J, K	Faint color—noticeable warmth

Standard used: D, E, or F grade (colorless) exclusively

Clarity Grade

Clarity indicates the presence of internal characteristics (inclusions) when examined under 10x magnification:

Grade	Meaning
FL, IF	Flawless / Internally Flawless
VVS1, VVS2	Very Very Slightly Included—extremely difficult to detect
VS1, VS2	Very Slightly Included—minor inclusions
SI1, SI2	Slightly Included—noticeable under magnification

Standard used: VVS1 grade (virtually flawless to the naked eye)

Cut Grade

Cut quality determines how well light travels through the stone, directly affecting brilliance and fire:

Grade	Light Performance
Excellent	Optimal light return and sparkle
Very Good	High light performance
Good	Adequate brilliance
Fair/Poor	Reduced sparkle

Standard used: Excellent cut grade for maximum brilliance

Carat Weight

Precise weight measurement recorded to 0.001 carat accuracy.

Additional Details

Your certificate also documents:

Measurements: Exact dimensions in millimeters (length × width × depth)
Shape: Round, oval, cushion, emerald, marquise, etc.
Proportions: Table percentage, depth percentage, crown and pavilion angles
Polish and Symmetry: Quality of finishing work
Unique Report Number: Individual identification for verification

Your Certificate, Explained

How to read your GRA report.

Every Meiara moissanite above one carat ships with its own GRA grading report. Here is what each section of that document tells you — and how to verify it yourself.

Layout of a Meiara GRA grading report — your own certificate ships with your piece.

1 Report number The unique ID for your stone. Use it to verify the report with GRA — it also matches the microscopic laser inscription on the stone itself.
2 Shape & measurements The cut (round brilliant, oval, emerald, cushion…) and the stone's exact millimetre dimensions.
3 The 4Cs Carat weight, colour, clarity and cut — the four measures that define quality. Meiara moissanite is typically D colour, VVS1 clarity, Excellent cut.
4 Finish & fluorescence Polish and symmetry describe how precisely the stone was cut. Fluorescence notes any glow under UV light.
5 Laser inscription The report number is inscribed on the stone's girdle — invisible to the eye, readable under magnification. This is what ties this certificate to this stone.
6 Proportions, clarity & scales A cross-section of how the stone was cut, clarity plot diagrams, and where your stone sits on the colour, clarity and cut scales.
7 Verification Scan the QR code or enter the report number at gra-moissanites.com to confirm the details independently. You never have to take our word for it.

A note on honesty: moissanite is not a diamond — it is silicon carbide, a distinct gemstone with its own brilliance and fire. GRA grading confirms your stone is genuine moissanite of the stated quality, and that the certificate belongs to the stone you received. Stones above one carat ship with their own GRA report.
