Moissanite Engagement Rings - Canada's Brilliant Ethical Alternative

Moissanite is one of the hardest, most optically brilliant gemstones on earth. It's also lab-created, conflict-free, and a fraction of the cost of a lab-grown diamond. I'm Suman Smith, founder of Lux Jewels, and I've been designing moissanite rings alongside lab-grown diamond rings since 2007. I don't position moissanite as "second best." It's a distinct gemstone with its own optical character - and for some couples, it's the right choice.

• Silicon carbide (SiC) - a distinct gemstone, not a diamond or simulant
• Mohs hardness 9.25 - suitable for everyday engagement ring wear
• Refractive index 2.65-2.69 vs diamond's 2.42 - more brilliance and rainbow fire
• Lab-created - no mining, no ethical supply-chain concerns
• Forever One by Charles & Colvard: the colourless standard in moissanite
• 2026 Canada pricing: C$250-C$600 for a 1ct-equivalent stone
• Does not cloud, yellow, or lose sparkle over time

What Is Moissanite?

Moissanite is a gemstone made of silicon carbide (SiC). It's not carbon, which means it's not a diamond - not a lab-grown diamond, not a natural diamond, not a diamond simulant. It's a separate gemstone entirely, with its own chemistry, its own optical properties, and its own certification standard.

Where Does Moissanite Come From?

In 1893, chemist Henri Moissan - who later won the Nobel Prize in Chemistry - found microscopic crystals in a meteor crater in Canyon Diablo, Arizona. He initially believed he'd found diamonds. Analysis revealed the crystals were silicon carbide, a compound previously unknown in nature. The gemstone was eventually named after him.

Natural moissanite exists only in trace amounts, found in certain meteorites and rock formations from high-pressure geological events. Every moissanite used in jewellery today is lab-created, grown from silicon and carbon in controlled conditions. It's not "artificial" in the sense of being fake - it's simply produced where natural occurrence is impossible at commercial scale.

Is Moissanite a Real Gemstone?

Yes - it's a certified, graded gemstone with its own identity. It's not trying to be a diamond. Moissanite has a distinct refractive index, a distinct fire signature, and its own grading standard. Charles & Colvard, the company that commercialized moissanite for jewellery in 1998, produces the Forever One line - the colourless industry benchmark.

If someone tells you moissanite is "fake" - they're confusing it with cubic zirconia, which is a different, much softer material. Moissanite is real. It just isn't a diamond.

Does Moissanite Pass a Diamond Tester?

This is worth a nuanced answer because most retailers give a binary yes or no.

Standard thermal conductivity diamond testers check how quickly heat moves through a stone. Diamond and moissanite both conduct heat at high rates, which means many thermal testers will read moissanite as "diamond." However, advanced multi-testers (like the DiamondSure or Presidium Multi Tester) can distinguish moissanite from diamond based on their different electrical conductivity properties.

The takeaway: on a standard store tester, moissanite often reads as diamond. On professional equipment, it reads as moissanite. That's not deception - it's physics. And any reputable jeweller who works with moissanite will tell you this upfront.

How Does Moissanite Compare to Lab-Grown Diamonds and Natural Diamonds?

This is where most buyers need a clear table, not marketing language. Here's the honest comparison.

The key visual difference in a finished ring: moissanite produces more rainbow colour flash than diamond, especially in sunlight. Some wearers love this. Others prefer the more subdued fire of a diamond. That's a preference, not a quality difference.

How Much Do Moissanite Engagement Rings Cost in Canada?

Moissanite is the most affordable premium gemstone option for engagement rings in Canada. In 2026, here's what you can expect to pay for the stone alone, before setting and design costs.

For reference, Canadian competitors show the following moissanite ring pricing (stone + setting):

• Bellisa Jewellery: CA$1,835-CA$2,643 for finished rings
• AGI Design: CA$1,680-CA$2,846 for finished rings
• Forever Ring: starting at CA$1,000

Pricing subject to change. Confirm current rate at stan.store/luxjewels before booking.

Does Moissanite Get Cloudy Over Time?

No. This is one of the most common concerns buyers bring to me, and the answer is a firm no.

Moissanite doesn't cloud, yellow, or lose brilliance with age. It has no internal carbon or organic compounds that can oxidize or degrade over time the way some other stones can. The hardness of 9.25 means it resists scratching from daily contact with most surfaces. What looks like cloudiness in moissanite is almost always surface-level contamination from soap, lotions, and skin oils - a 30-second cleaning with warm water and mild dish soap restores full sparkle.

The distinction worth knowing: cubic zirconia (CZ) does cloud and yellow over years. Moissanite doesn't. They're frequently confused, which is where the concern comes from.

Why Choose Moissanite for an Engagement Ring?

The Budget Argument

If your budget can get you a 0.75ct lab-grown diamond or a 2ct moissanite in the same 14K setting, and both options involve a durable, brilliant, certified gemstone - moissanite lets you go significantly larger for the same spend. For couples where visual size matters more than the specific gemstone type, that's a straightforward calculation.

The Ethics Argument

Moissanite is entirely lab-created. There's no mining, no excavation, no supply-chain sourcing from conflict regions. The environmental footprint is lower than natural diamond mining by a significant margin. It's also lower than lab-grown diamond production, which requires considerable electricity for the growth process. If environmental minimalism is the priority, moissanite wins.

The Optical Argument

Moissanite's refractive index of 2.65-2.69 is higher than diamond's 2.42. That means moissanite returns more light - both white light (brilliance) and coloured light (fire). In a ring, this produces the rainbow flash many wearers find beautiful. It's a different optical signature than a diamond, not a lesser one.

The Honesty Argument

Some couples simply want a beautiful ring that doesn't cost three months' salary - and they don't want to pretend otherwise. Moissanite is a strong, honest choice: a real gemstone with real certification, at a price that lets you start a life together without financial strain.

Forever One by Charles & Colvard - The Moissanite Standard

Not all moissanite is equal. The clarity and colour consistency of moissanite stones varies by manufacturer. Charles & Colvard - the original patent holder who first commercialized moissanite for jewellery in 1998 - produces the Forever One line, which is the colourless standard in moissanite grading.

Forever One moissanite grades are:

• Colourless (D-E-F equivalent): the clearest, most diamond-like colour range
• Near-colourless (G-H-I equivalent): a slight warmth that's less visible in yellow or rose gold settings

For white gold or platinum settings, I always recommend colourless grade Forever One. The colour difference is subtle, but the higher grade holds better in a white metal context.

At Lux Jewels, I source Charles & Colvard Forever One for all moissanite custom designs.

Popular Moissanite Ring Styles

Oval Moissanite Engagement Rings

Oval moissanite in a solitaire or hidden halo setting is one of my most-requested designs. The elongated shape maximizes visual size per dollar, and moissanite's high refractive index means an oval moissanite produces exceptional sparkle from every angle.

Emerald Cut Moissanite Rings

Emerald cut moissanite shows a distinctive hall-of-mirrors effect in the step-cut facets. At this cut, the moissanite's rainbow fire is more subtle - the long facets show depth over flash, which suits the architectural aesthetic of emerald cut design.

Round Brilliant Moissanite Rings

Round brilliant is the classic. Moissanite's refractive index means a round moissanite produces maximum brilliance and fire - more than a round diamond of the same size. If you want maximum sparkle per dollar, this is the combination.
