1. Moissanite Color Grades

Moissanite is graded based on its colorlessness, following a scale similar to diamonds:

• Colorless (D-E-F): These stones are completely clear and are considered the highest quality. They offer the most brilliance and sparkle.
• Near-Colorless (G-H-I): These stones have a very slight warm tint, often only visible when compared side-by-side with a colorless stone. They offer excellent value.
• Faint Color (J-K): These stones have a more noticeable warm or yellowish tint, which may be preferred by those looking for a vintage aesthetic.

2. Moissanite Clarity Grades

Clarity refers to the presence of internal inclusions or external blemishes. Common grades include:

• FL/IF (Flawless/Internally Flawless): No inclusions visible under 10x magnification.
• VVS1/VVS2 (Very, Very Slightly Included): Tiny inclusions that are difficult for even a professional to see under magnification.
• VS1/VS2 (Very Slightly Included): Small inclusions that are visible under magnification but typically eye-clean.

3. Moissanite Cut Grades

The cut is arguably the most important factor in determining a stone’s sparkle. Grades include:

• Excellent Cut: Maximizes light reflection and fire.
• Very Good Cut: Offers high brilliance but may have slight deviations in symmetry.
• Good Cut: Reflects a significant amount of light but lacks the intense fire of higher grades.

4. Carat Weight vs. Size

Moissanite is often sold by millimeter size rather than carat weight because it is lighter than diamond. For example, a 6.5mm moissanite is equivalent in size to a 1.0ct diamond. See our Ultimate Size Guide for more information.
