When shopping for moissanite jewelry—especially engagement rings—understanding how quality is assessed can help you make a confident and informed decision. Like diamonds, moissanite is graded using the globally recognized 4Cs: carat, color, clarity, and cut. Each of these attributes influences the gemstone’s brilliance, beauty, and overall value.
In this guide, we’ll break down how each C applies to moissanite, what to look for, and how to choose the right stone for your needs and budget.
1. Carat: Understanding Moissanite Size
Carat measures the weight of a gemstone, but in moissanite, size can appear slightly different compared to diamonds due to its lower density.
A 1-carat moissanite may appear slightly larger than a 1-carat diamond.
Moissanite is available in a wide range of carat sizes, from delicate solitaires to bold statement pieces.
Because moissanite is more affordable per carat than diamonds, many shoppers can opt for larger stones without compromising quality or budget.
Pro Tip: If you want maximum visual impact, moissanite allows you to size up affordably while still getting a premium-looking ring.
2. Color: Moissanite’s Shades from D to J
Moissanite comes in a range of colors, most often classified using the diamond color grading scale from D (colorless) to J (near colorless).
D–F Color Grade: Completely colorless and icy white. These are the most desirable and rare, offering a clean, brilliant sparkle.
G–H Color Grade: Near-colorless. Slight warmth under specific lighting, but still appears white in most settings.
I–J Color Grade: Slightly warmer tone, with subtle hints of yellow. Still beautiful and highly affordable, especially when paired with yellow or rose gold settings.
Moissanite’s refractive properties can sometimes give it a disco-ball rainbow sparkle. Colorless moissanite minimizes this effect for those who prefer a diamond-like look.

3. Clarity: How Inclusions Affect Moissanite
Like diamonds, moissanite clarity refers to the presence of internal or external imperfections, known as inclusions or blemishes.
Clarity is typically graded as:
FL (Flawless): No inclusions or blemishes visible under 10x magnification.
IF (Internally Flawless): No internal flaws; very minor surface blemishes.
VVS1–VVS2 (Very Very Slightly Included): Extremely tiny inclusions, difficult to detect even under magnification.
VS1–VS2 (Very Slightly Included): Minor inclusions visible under magnification but not to the naked eye.
SI (Slightly Included): Inclusions visible under 10x magnification, sometimes to the naked eye, but often not distracting.
Note: Most moissanite on the market falls in the VVS to VS clarity range, offering incredible sparkle and clarity at great value.
4. Cut: The Key to Moissanite’s Fire and Brilliance
While diamonds rely heavily on cut for sparkle, moissanite naturally has higher refractive and dispersion properties, making it incredibly fiery and brilliant regardless of the cut. That said, a quality cut still enhances its appearance.
Popular moissanite cuts include:
Round Brilliant: Maximizes fire and sparkle; the most classic and popular cut.
Oval & Emerald: Elegant and elongating; emerald cuts show less fire but more depth.
Cushion & Radiant: Soft, modern shapes with stunning light play.
Princess: Contemporary and bold with sharp corners.
Always look for excellent or very good cut grades, as these indicate expert craftsmanship and optimal symmetry.
Why Quality Matters: Choosing the Best Moissanite for You
While moissanite is a more affordable alternative to diamonds, that doesn’t mean you have to compromise on quality. Whether you’re shopping for a moissanite engagement ring, a pendant, or a pair of earrings, understanding the 4Cs ensures you’ll find the right balance of sparkle, size, and value.
Many top-tier moissanite brands today offer stones that reach D color and IF clarity, setting a new standard for lab-grown brilliance. These stones are exceptionally white, flawless to the eye, and beautifully cut for maximum fire.
Caring for Your Moissanite
Moissanite is incredibly durable (9.25–9.5 on the Mohs scale), making it suitable for daily wear. To keep it sparkling:
Soak in warm water with mild dish soap.
Use a soft toothbrush to gently remove any residue.
Rinse and dry with a lint-free cloth.
Store separately to avoid contact with other jewelry and scratches.
