Spotting Moissanite Diamonds: Essential Tips for Identification
When it comes to buying diamonds, it’s important to know what you’re getting. Moissanite diamonds have gained popularity in recent years due to their brilliance and affordability. However, it’s crucial to be able to distinguish moissanite from traditional diamonds. In this article, we will provide you with essential tips to help you identify moissanite diamonds.
Understanding Moissanite
Moissanite is a gemstone that closely resembles a diamond in appearance. It was first discovered in 1893 by Henri Moissan, a French scientist, in a meteor crater in Arizona. However, moissanite is incredibly rare in its natural form, so most moissanite used in jewelry today is lab-created.
Moissanite vs. Diamonds: Key Differences
While moissanite and diamonds may look similar to the untrained eye, there are several key differences to look out for:
1. Brilliance: Moissanite has a higher refractive index than diamonds, which means it reflects more light and has greater brilliance. This can give moissanite a “rainbow effect” or “disco ball” appearance, especially under certain lighting conditions.
2. Color: Most diamonds are graded on their lack of color, with the most valuable diamonds being completely colorless. Moissanite, on the other hand, often has a slight yellow or grayish hue, especially in larger sizes.
3. Hardness: Diamonds are the hardest natural substance on earth, ranking 10 on the Mohs scale of hardness. Moissanite is also very hard, but slightly lower on the scale at 9.25. This means that moissanite is still very durable, but it may be more susceptible to scratches over time.
4. Price: One of the most significant differences between moissanite and diamonds is the price. Moissanite is much more affordable than diamonds of similar size and quality, making it an attractive option for those on a budget.
Tips for Identifying Moissanite Diamonds
Now that you know the key differences between moissanite and diamonds, here are some essential tips to help you spot moissanite:
1. Use a Diamond Tester: Diamond testers are handheld devices that can quickly determine if a stone is a diamond or moissanite. These testers work by measuring electrical conductivity, as moissanite and diamonds have different electrical properties.
2. Look for Double Refraction: Moissanite has a higher refractive index than diamonds, which means it can create a “double refraction” effect. To test for this, place the stone on a piece of paper with lines or text. If you see a doubling or blurring effect through the stone, it may be moissanite.
3. Check for Rainbow Colors: As mentioned earlier, moissanite can exhibit a “rainbow effect” due to its high refractive index. If you see flashes of rainbow colors when moving the stone under light, it may be moissanite.
4. Examine the Stone Under Different Lighting: Moissanite may appear more yellow or grayish under certain lighting conditions, such as fluorescent lights. To get a better idea of the stone’s true color, examine it under natural daylight or incandescent lighting.
Conclusion
Identifying moissanite diamonds can be challenging, but with these essential tips, you can confidently spot the differences between moissanite and traditional diamonds. Remember to use a diamond tester, look for double refraction, check for rainbow colors, and examine the stone under different lighting conditions. By paying attention to these details, you can ensure that you’re getting the gemstone you desire.
