Following are some of the best faux diamonds you could get on the market.
Arguably the best faux diamond in existence, moissanite comprises silicon carbide, which means it is almost of the same hardness as a natural diamond. It also has reasonable colorlessness, although the glow is far more colorful than what you would see in a real diamond.
Shortened to CZ, this gem is highly popular for its low price. It is made up of zirconium dioxide, and hence has a lower hardness than moissanite at 8 to 8.5 on the Mohs’ scale. This means CZ requires careful handling to avoid scratches, which could reduce its brilliance.
Similar to real diamond in appearance as well as close to it in hardness (9 in 10), white sapphire lacks color, for the most part, making it a good choice when you are shopping for a faux diamond. It does cost more than CZ though, so you need to check your budget before making a purchase.
