Thinking about a moissanite engagement ring or moissanite jewellery but not sure if it’s the right fit? You’re not alone. This sparkling stunner has become more and more popular as a brilliant, ethical, and affordable alternative to diamonds.

Whether you're in the early stages of ring shopping or just curious about this cosmic gem, here's everything you need to know—straight from your trusted source - nzjewellers.

What Is Moissanite?

Moissanite is a lab-created gemstone made from silicon carbide. Although it looks nearly identical to a diamond, it actually sparkles even more—thanks to a higher refractive index. It’s also 9.25 on the mohs scale of hardness, putting it right up there with diamond. It is also geologically tough, making it ideal for everyday wear like engagement rings and wedding bands.

Where Does Moissanite Come From?

Believe it or not, moissanite was first discovered in 1893 by scientist Henri Moissan in a meteorite crater in Arizona. That’s right—this gem quite literally fell from the stars - and is out of this world. Since natural moissanite is extremely rare, today’s stones are grown in labs using advanced technology, making them traceable and eco-conscious, but also chemically, optically and physically identical to their cosmic original.

How Is Moissanite Made?

Creating moissanite involves heating silicon carbide to high temperatures and pressures to mimic the conditions under which it forms naturally. The result? A gorgeous, conflict-free gemstone that takes months to grow, sparkles like nothing on earth, and lasts a lifetime.
