Moissanite can pass a basic diamond tester, particularly those that measure thermal conductivity. However, more advanced diamond testers, which also assess electrical conductivity, can accurately differentiate between moissanite and diamonds. While moissanite and diamonds share some similar properties, these more sophisticated tests reveal their distinct compositions.

Moissanite presents a highly affordable and visually comparable alternative to diamonds for engagement rings, offering exceptional durability along with superior brilliance and fire. While diamonds are the hardest known natural material with a perfect 10 on the Mohs scale of hardness, moissanite ranks just behind at 9.25. This makes both gemstones well-suited for everyday wear, providing long-lasting beauty and resilience.

Moissanite bears a striking resemblance to diamond, but it is not a "fake" diamond. Rather, it is a distinct gemstone with its own unique properties and origins. A helpful comparison is the concept of doppelgängers, unrelated individuals who happen to look remarkably alike. Similarly, moissanite and diamond may appear nearly identical to the untrained eye, yet they are entirely different in composition and formation.

No. Moissanite is made of silicon carbide, while cubic zirconia is made of zirconium dioxide. An exceptionally cheap, man-made stone, cubic zirconia entered the jewellery market in the 1970s. It looked so similar to a diamond that it was soon used to dupe unsuspecting customers into thinking that they had bought a diamond. In recent years cubic zirconia has gotten a rebrand as CZ and is often sold as itself as a cheap diamond alternative on fashion jewellery sites.

No. Carat weight does not measure the size of a stone, rather its weight. Different gems have different densities which is why two different gemstones of identicial size can in fact have different carat weights. Since moissanite is 15% lighter than a diamond a 1 carat moissanite is smaller than a 1 carat diamond.

Absolutely! At first glance they may appear pretty similar: both give you the wonderful clear sparkle of a diamond. However, while moissanite will retain its same brilliance, colour and clarity for a lifetime (and beyond!) cubic zirconia starts to lose its sparkle after just a few years. Cubic zirconia gets irreversibly cloudy over time as it is a porous stone that absorbs oils from the skin and chemicals and dirt from exposure to everyday life. Cubic zirconia is also less scratch resistant than moissanite and its sharp edges have a tendency to become rounded and dull over time. Put simply: a moissanite engagement ring is a forever ring, a cubic zirconia ring is temporary.

Yes. Moissanite is a beautiful, naturally occurring mineral called silicon carbide. It was first discovered in 1893 in a meteor crater in Arizona. As it is exceptionally rare in nature the only way to supply gems to the jewellery market is to recreate it in a lab setting. Moissanite made in a lab has identical properties to its natural counterpart. Just because the moissanite on the market has been made in a lab does not make it fake.
