Moissanite Engagement and Promise Rings

Moissanite is not a diamond. It is silicon carbide, a separate gemstone first identified in a meteorite crater in 1893 and now grown in laboratories. It is the closest stone to diamond in hardness and the only one that out-sparkles it. Every ring in this collection is set with moissanite, never lab grown diamond, and each is made to order in 9K, 14K or 18K solid gold.

How is moissanite different from a lab grown diamond?

Different material entirely. A lab grown diamond is carbon and tests as diamond because it is diamond. Moissanite is silicon carbide and tests as moissanite. Moissanite has higher refractive index, so it throws more coloured light, often called fire, which some people prefer and others find too flashy for an engagement ring.

How hard is moissanite?

9.25 on the Mohs scale, against 10 for diamond. That makes it the second hardest gemstone used in jewelry and entirely suitable for daily wear over decades.

Frequently asked questions

Will it pass a diamond tester? A basic thermal tester may read it as diamond. A modern dual tester distinguishes them correctly. Ronora never sells moissanite as diamond.

Why choose moissanite? Price, and fire. It costs considerably less per carat than a lab grown diamond and sparkles more brightly.

More Fire Than Diamond

Moissanite refracts light more strongly than diamond does. The result is bursts of rainbow colour rather than white flash, and you either love it or you do not.

Hard Enough For Every Day

At 9.25 on the Mohs scale moissanite sits just below diamond and well above sapphire. It handles daily wear without scratching.

Honest About What It Is

These rings are moissanite and we say so in the title, the description and the details. We do not blur the line between moissanite and diamond anywhere on this site.

What is moissanite?

Moissanite is a lab created gemstone made of silicon carbide. It is a distinct stone in its own right, not a diamond simulant pretending otherwise, and it is prized for exceptional brilliance and fire.

Is moissanite the same as a lab grown diamond?

No. A lab grown diamond is chemically diamond; moissanite is silicon carbide. They are different stones with different optics and different prices, and every Ronora ring states which one it is.

How can you tell moissanite from diamond?

By the fire. Moissanite splits light into visible rainbow flashes far more than diamond does, which is most obvious under direct light.

Is moissanite durable enough for an engagement ring?

Yes. It rates 9.25 on the Mohs hardness scale, which makes it one of the hardest gemstones available and entirely suitable for everyday wear.

Why choose moissanite over diamond?

Price and fire. Moissanite costs substantially less at the same size, and some people simply prefer its stronger rainbow brilliance to a diamond's whiter sparkle.

Do moissanite rings come with a certificate?

Moissanite is not graded by diamond laboratories, so these rings do not carry IGI reports. Every stone's size and quality is stated clearly on the product page instead.
