Spotting Moissanite Diamonds: Essential Tips for Accurate Identification
Moissanite diamonds have gained popularity in recent years as a more affordable and ethically sourced alternative to natural diamonds. However, due to their striking resemblance to real diamonds, it can be challenging to spot the difference between the two. In this article, we will provide you with essential tips for accurately identifying moissanite diamonds.
Understanding the Properties of Moissanite
Moissanite is a lab-created gemstone that closely resembles a diamond in appearance. It is composed of silicon carbide and has a high refractive index, which gives it a brilliant sparkle. Moissanite is nearly as hard as a diamond, scoring 9.25 on the Mohs scale, just below the hardness of a diamond which scores a perfect 10.
Differences in Brilliance and Fire
One of the key differences between moissanite and diamonds lies in their brilliance and fire. Moissanite has a higher refractive index than a diamond, which means it reflects more light and exhibits greater brilliance. Additionally, moissanite has a higher dispersion than a diamond, resulting in more colorful flashes of light, also known as fire. If you observe a gemstone with intense brilliance and fire, it is likely to be a moissanite.
Examine the Color
Color is another factor to consider when identifying moissanite diamonds. While diamonds come in a range of color grades, from colorless to yellow or brown, moissanite typically exhibits a slight yellow or green hue. However, it is important to note that colorless moissanite does exist, so this should not be the sole indicator of whether a stone is a moissanite or a diamond.
Double Refraction
Another characteristic that distinguishes moissanite from diamonds is double refraction. When you look through a moissanite stone from the top, you may notice a doubling of the facets or edges. This effect is caused by the stone’s double refraction properties. On the other hand, diamonds do not exhibit this phenomenon, and their facets appear single and sharp.
Using a Diamond Tester
If you are still uncertain about the authenticity of a diamond, you can use a diamond tester. These handheld devices measure the thermal conductivity of the stone, which differs between diamonds and moissanite. A diamond tester will typically indicate whether the stone is a diamond or if it is moissanite or another gemstone.
Consult a Professional
When in doubt, it is always best to consult a professional gemologist or jeweler who has experience in identifying diamonds and moissanite. They have the expertise and tools to accurately determine the nature of the stone and provide you with reliable information.
Conclusion
Identifying moissanite diamonds can be a challenge due to their similarities with natural diamonds. By understanding their properties, examining their brilliance, fire, color, and looking for signs of double refraction, you can increase your chances of accurately identifying moissanite. If you are still unsure, using a diamond tester or seeking professional advice can provide you with the confirmation you need.
