Moissanite diamonds have gained popularity in recent years due to their high hardness (reaching up to 9.25, second only to natural diamonds) and remarkable brilliance. These gems are resistant to wear and can maintain their luster and fire even after prolonged wear.
However, the increasing demand for Moissanite diamonds has led to a flood of brands, making it challenging for consumers to make the right choice. In this blog, we will dissect Moissanite diamonds based on color, clarity, cut, durability, and resistance to oxidation, helping you select the wholesale Moissanite stone that suits you best.
1. Color
Moissanite diamonds are graded on a scale from D to M, with D being the highest quality in terms of colorlessness and M having noticeable color.
The research and technology behind Moissanite diamonds were initiated abroad, and the finest ones can achieve a color grade as high as D or F. However, the Moissanite diamond cultivation technology in China still lags slightly behind, with the highest color grade attainable being around G.
Common Moissanite diamonds tend to have a yellowish tint, often marked as G color. For the best quality, aim for D color Moissanite diamonds, provided your budget allows for it.
Choosing a higher color grade not only enhances the Moissanite’s fire but also increases its price.
2. Clarity
Lower clarity levels in Moissanite diamonds can lead to reduced transparency and brightness, potentially giving the diamond a cloudy or milky appearance. High-quality Moissanite brands consistently meet the minimum clarity standards.
Currently, the highest clarity grade available in the market is often attributed to Belgian Star Diamonds, whereas domestic brands may exhibit lower clarity, with some imperfections in facets, polish, and symmetry.
3. Cut
The cut of a Moissanite diamond significantly influences its brilliance. If the cut is too deep or too shallow, it can diminish the diamond’s brightness and make it appear darker.
In the 4C grading system (Cut, Clarity, Carat, Color), it is recommended to select a Moissanite diamond with a cut grade of 3EX, which stands for EXCELLENT in cut, polish, and symmetry. The combination of these three factors results in a 3EX grade, which represents the perfect cut. Moissanite diamonds with a 3EX cut exhibit the best fire and brilliance.
4. Carat Weight
Moissanite diamonds are measured in carats, with 1 carat equal to 200 milligrams or 0.2 grams. Moissanite carat weights are further divided into points, with 100 points equaling 1 carat. A 0.75-carat Moissanite is often referred to as 75 points.
It is recommended to choose a Moissanite diamond of at least 1 carat. Diamonds below 50 points may not showcase the full potential of Moissanite’s brilliance.
5. Durability
Currently, Moissanite diamonds, when compared to other gemstones, have a relatively high level of durability. Belgian Star Diamonds, produced in the diamond kingdom of Belgium, are known for their exceptional durability.
However, most Moissanite brands are resilient for everyday wear due to their high hardness. Nevertheless, excessive friction or force can still result in varying degrees of scratches, as Moissanite’s hardness is close to a perfect 10 on the Mohs scale, though not quite equal to it.
6. Oxidation and Corrosion Resistance
Moissanite jewelry may come into contact with substances like hand sanitizer, shower gels, or cosmetics during everyday wear, which can cause varying degrees of corrosion. However, Belgian Star Diamonds are generally of higher quality and exhibit superior resistance to oxidation and corrosion compared to domestically produced Moissanite diamonds. Of course, this quality comes at a higher price point.
In conclusion
when selecting wholesale Moissanite diamond from Moissanite manufacturer, consider the above factors. By understanding these key aspects, you can make an informed decision and choose a Moissanite diamond that suits your preferences and budget.
