What is the Difference Between Moissanite and Diamond?

Moissanite and diamond are both popular choices for engagement rings and other jewelry, but they have several key differences:

1. Hardness: Diamonds are slightly harder than moissanite. Moissanite ranks 9.25 on the Mohs scale, while diamonds rank 10 on the Mohs scale.
2. Fire and Brilliance: Moissanite has more fire and brilliance than diamonds. Moissanite has a refractive index of 2.65-2.69, while diamonds have a refractive index of 2.42. Moissanite's fire is rated at 0.104, which is higher than diamond's fire rating.
3. Weight: Moissanite is 15% lighter than diamonds, which means it weighs less per carat. Due to this difference in weight, moissanite is usually sold by length and width in millimeters rather than carat weight.
4. Clarity: Moissanite generally has a higher clarity than diamonds because it is created in a lab, whereas diamonds are formed naturally and often contain inclusions.
5. Color: Moissanite is not colorless, unlike diamond, and is not assessed and graded on color. Typical moissanite is similar in color to a GIA-certified K-color diamond, which falls in the faint color scale rather than colorless or near-colorless. Moissanite also emits a different kind of brilliance than diamonds due to its different faceting pattern, with fiery, rainbow flashes.
6. Affordability: Moissanite is more affordable than diamonds, making it an attractive option for those seeking a budget-friendly alternative.

In summary, moissanite and diamond differ in hardness, fire, brilliance, weight, clarity, color, and affordability. While their appearances may be similar, these differences can impact the overall value and look of the stone in jewelry.
