Any Other Differences Between Lab Diamonds and Moissanites?
Colour change in moissanites. The easiest way to test this is by bringing the stone close to direct fire for a few seconds. This will make the stone go green in colour.
Moissanites have smooth girdles whereas Diamonds have faceted girdles. Diamonds in general are cut differently - given the price tag of a diamond a lot more effort goes into the cutting of one.
Diamonds are harder than moissanites. In fact, diamonds are the hardest material found in nature. It is true that diamonds are forever. Moissanites, however, are the hardest out of all other simulants such as cubic zirconia, etc. Yet, moissanites are three times less hard than diamonds, which makes the former tend to scratch easier. Another way to differentiate diamonds from moissanites is that the latter are denser and heavier, which makes the former more comfortable to wear.
Lab Diamonds Vs Moissanites: Truth or False?
TRUE: Moissanites have a brown tint in colour on average, “J” when comparing it to a diamond colour grading system.
FALSE: Moissanites can be made white in colour (colourless).
TRUE: Moissanites sparkles are iridescent in colour while diamonds’ sparkles are white.
FALSE: Moissanites sparkle similarly or identical in colour to diamonds.
TRUE: All moissanites suffer from double refraction no matter how they are cut or polished.
FALSE: There is a way to cut moissanites to eliminate double fraction.
TRUE: Moissanites resemble costume jewellery due to the iridescent sparkles they produce.
FALSE: Moissanites are cut to the same standards as diamonds.
TRUE: Moissanites go green when exposed to direct fire.
Note: As we explain in detail in our lab grown diamonds guide, the typical moissanite tester in the market cannot be used to test lab diamonds. Beware of dishonest jewellers pulling tricks on naive customers, its done by using a moissanite testers on lab diamond rings to show a false reading as if the lab grown diamond was a moissanite.
Diamonds and moissanites look different due to various factors. Moissanites tend to have tints and are often "J" in color, while diamonds can be colorless. Moissanites produce iridescent sparkles, while diamonds exhibit white sparkles. Moissanites exhibit double refraction due to their material, and this property cannot be eliminated by cutting or polishing. Moissanites are also denser and heavier than lab made diamonds in UK, making them less comfortable to wear. Lab created diamonds in UK are harder, making them more durable. Some companies may provide misleading information about moissanites, so it`s essential to be aware of the differences.
