A. Does moissanite lose its shine?
Moissanite does not lose its sparkle and continues to shine as the months go by. The clarity and color of the stone will not change over time, but as with any gemstone, stains on the stone's surface can inhibit its brilliance. However, moissanite is resistant to oil, making it less prone to fogging and easier to clean.

A. What is moissanite?
Moissanite is a rare natural mineral composed of silicon carbide (SiC), discovered by Nobel Prize-winning chemist Dr. Henri Moissan in a crater created by a meteorite impact in Arizona. Moissanite, due to its structure, has excellent durability and is 2.5 times more brilliant than diamonds. It is also significantly less expensive than diamonds and in recent years has been widely used for fashion jewelry as well as engagement rings.

Is moissanite durable?
A. Moissanite is one of the most durable gemstones available. Diamonds have a cleavage property that can cause them to crack or chip upon impact during normal use, but moissanite has no cleavage property and boasts superior toughness compared to diamonds. Moissanite also has a high Mohs hardness rating of up to 9.6, which indicates the surface's susceptibility to scratching, making it ideal for engagement rings and other jewelry worn daily.

Can you tell the difference between Moissanites and Diamonds? 
A. Moissanite passes as a diamond when using a diamond tester that detects thermal conductivity. This is because, unlike other gemstones such as cubic zirconia, it has a high thermal conductivity. Such moissanite (silicon carbide) is similar to diamond in appearance and characteristics, but it is composed of a different substance than diamond (carbon). Moissanite, which is extremely durable, brilliant, lustrous, and heat resistant, has gained popularity among people due to its attractiveness as a gemstone.

Can I tell a moissanite from a diamond?
A. Moissanite and diamonds are so similar in appearance that it is difficult to visually distinguish them, but they can be identified using a device called a moissanite tester, which is used to distinguish between the two. Another method is to use a loupe to look at the top of the gemstone from an angle. In moissanite, you will see two slightly blurred lines, indicating double refraction.
