Do round shape moissanites change color over time?

As a supplier of round shape moissanites, one question that I often get asked is, "Do round shape moissanites change color over time?" This is a valid concern, especially for customers who are investing in these beautiful gemstones. In this blog post, I will delve into the science behind moissanite, discuss whether they change color, and provide some insights based on my experience in the industry.

Understanding Moissanite

Moissanite is a lab - created gemstone that was first discovered in a meteorite crater by Dr. Henri Moissan in 1893. Its chemical composition is silicon carbide (SiC). Naturally occurring moissanite is extremely rare, so most of the moissanite available in the market today is synthetic.

The round shape is one of the most popular cuts for moissanite, just like it is for diamonds. It offers a classic and timeless look, with excellent light return and fire. When properly cut, round moissanites can rival the beauty of diamonds.

The Color of Moissanite

Moissanite typically comes in a range of colors, from near - colorless to slightly yellow or green. The Gemological Institute of America (GIA) has a color grading scale for diamonds, but there isn't a standardized scale for moissanite. However, most high - quality round shape moissanites are near - colorless, which is highly desirable for jewelry.

The color of moissanite is determined by its chemical purity and the manufacturing process. During the creation of moissanite in a laboratory, scientists carefully control the conditions to produce gemstones with the desired color and clarity.

Do Round Shape Moissanites Change Color Over Time?

In general, high - quality round shape moissanites do not change color over time. The synthetic process used to create moissanite results in a stable gemstone with consistent properties. Unlike some organic gemstones or materials that can be affected by environmental factors, moissanite is chemically stable.

The silicon carbide structure of moissanite is very strong. It has a high hardness (9.25 on the Mohs scale, second only to diamonds), which means it is resistant to scratches and abrasions. This hardness also contributes to its chemical stability.

However, there are some rare cases where a moissanite might appear to change color. One reason could be surface contamination. If a moissanite is not properly cleaned and dirt, oil, or other substances build up on its surface, it can affect the way light passes through the gemstone, making it seem like the color has changed. Regular cleaning with a mild soap and water solution and a soft brush can prevent this issue.

Another factor could be the setting of the moissanite. Some metals used in jewelry settings can react with the environment or release substances that might come into contact with the moissanite. For example, if a low - quality metal oxidizes, it could leave a residue on the moissanite, altering its appearance. Choosing high - quality settings and having the jewelry properly maintained can mitigate this risk.

Quality and Color Stability

As a supplier, I always emphasize the importance of quality when it comes to moissanite. Higher - quality round shape moissanites are more likely to maintain their color over time. These gemstones are created using advanced manufacturing techniques that ensure a more consistent chemical composition.

For example, our 2ct Round Moissanite is crafted with precision to achieve excellent color and clarity. We source our moissanite from trusted manufacturers who adhere to strict quality control standards.

Similarly, our Moissanite Stone collection is carefully selected to offer customers gemstones with long - lasting color and beauty. Each stone is inspected to ensure it meets our high - quality criteria.

Hearts and Arrows Moissanite

Our Hearts and Arrows Moissanite is a special type of round shape moissanite. This cut is designed to maximize the light return and create a unique pattern of hearts and arrows when viewed through a special viewer. The precision cutting of Hearts and Arrows moissanite not only enhances its visual appeal but also contributes to its color stability. The careful cutting process ensures that the gemstone's internal structure is uniform, which helps in maintaining its color over time.

Maintaining the Color of Round Shape Moissanites

To keep your round shape moissanite looking its best and prevent any potential color - related issues, here are some tips:

• Regular Cleaning: As mentioned earlier, clean your moissanite jewelry regularly. You can use a mild dish soap and warm water. Soak the jewelry for a few minutes, then gently scrub it with a soft - bristled brush. Rinse thoroughly and dry with a soft cloth.
• Proper Storage: Store your moissanite jewelry separately from other jewelry pieces to prevent scratches. You can use a soft jewelry pouch or a lined jewelry box.
• Avoid Harsh Chemicals: Keep your moissanite away from harsh chemicals such as bleach, chlorine, and strong acids. These substances can damage the gemstone and potentially affect its appearance.

Conclusion

In conclusion, high - quality round shape moissanites generally do not change color over time. Their chemical stability and the advanced manufacturing processes used in their creation ensure that they maintain their beauty and color for years to come. However, proper care and maintenance are essential to keep them looking their best.

If you are interested in purchasing round shape moissanites, whether it's a 2ct Round Moissanite, a Moissanite Stone, or a Hearts and Arrows Moissanite, I invite you to get in touch with me for further discussion. We can talk about your specific requirements, such as size, color, and budget, and find the perfect moissanite for you.
