Moissanite vs Diamond: What to Know

Moissanite has moved from a niche diamond alternative to a genuine favorite in its own right, and for good reason: it's brilliant, durable, and a fraction of the cost of a mined diamond.

What is moissanite made of?

Moissanite is a lab-created gemstone made from silicon carbide. It was originally discovered in a meteorite crater, and today it's grown in labs to be completely consistent in clarity and cut.

Is moissanite as durable as a diamond?

Nearly. Moissanite scores 9.25 on the Mohs hardness scale, just below a diamond's 10, making it more than durable enough for daily wear, including rings worn every day.

Does moissanite sparkle like a diamond?

Moissanite actually has a higher refractive index than diamond, which means it can appear even more brilliant and fiery under light. Some people prefer this extra sparkle; others prefer the more subdued brilliance of a diamond.

How can you tell moissanite from a diamond?

To the naked eye, high-quality moissanite is very difficult to distinguish from a diamond. Jewellers use specialized testers that measure thermal and electrical conductivity to tell them apart, since the two stones respond differently.

Is moissanite a good choice for an engagement or promise ring?

Yes. Moissanite offers the look and durability suited to daily wear at a much lower price point, making it a practical choice for engagement rings, anniversary gifts, or simply treating yourself.

Does moissanite need special care?

Not really. A soft cloth and mild soap and water are enough to keep it clean and brilliant. It resists scratching well, though like any fine jewellery it's best removed before heavy manual work.
