Moissanite and diamond are two extremely popular precious gemstones in the jewelry industry. Many people’s love for moissanite is partly due to its beauty and brilliance, but more importantly, its hardness and ability to scatter light, making it visually similar to diamond. However, many consumers are confused by the fact that moissanite can pass diamond testers.
First, diamond testers usually determine whether a gemstone is a diamond by measuring its thermal conductivity. Diamond has extremely high thermal conductivity, while moissanite’s thermal conductivity is also relatively high, although slightly lower than diamond, but enough to make many ordinary testers mistake it for a diamond. Because of this, many moissanites may pass the test and be mistaken for diamonds without further analysis.
In addition, moissanite’s optical properties are also excellent, with a better refractive index and dispersion than diamond. When light passes through moissanite, its flash and fire give a visual effect that is very similar to diamond. Therefore, in terms of appearance and brilliance, moissanite is often regarded by consumers as a substitute for “diamond”.
Consumers still need to be vigilant when purchasing. Although moissanite can pass the diamond tester, it is significantly different from diamond in terms of chemical composition, value and rarity. To identify the true value of a gemstone, you need to rely not only on the tester results, but also consult a professional jewelry appraiser to ensure that the gemstone you buy truly meets your expectations.
