Moissanite vs. Lab-Grown Diamonds: Which Is Better for You?
Moissanite vs. lab-grown diamonds: which is right for you? Both offer beautiful sparkle, impressive durability, and the freedom to choose jewelry that reflects your style. But they are not the same gemstone, and understanding their differences can help you make a purchase you'll feel confident about for years.
Perhaps you love the rainbow fire of moissanite. Or maybe you've always dreamed of owning a genuine diamond. Today, Canadian shoppers can enjoy both options without automatically choosing a mined diamond.
At MOISS & ICE, we offer premium moissanite engagement rings alongside lab-grown diamond engagement rings. This guide compares their appearance, cost, durability, and certification so you can decide which gemstone is right for you.
What Is the Difference Between Moissanite and Lab-Grown Diamonds?
The biggest difference is their chemical composition.
- Moissanite is a gemstone made of silicon carbide. It has its own distinctive optical properties, including exceptional rainbow fire.
- Lab-grown diamonds are genuine diamonds made of carbon. They have essentially the same chemical, physical, and optical properties as mined diamonds.
Both are produced in controlled laboratory environments, but moissanite is not a diamond substitute in a chemical sense. It is a separate gemstone with its own beauty and characteristics.
Visual Appearance
Both gemstones can look remarkably beautiful in an engagement ring, but their sparkle has a different character.
- Moissanite: Known for vibrant rainbow flashes, particularly under direct lighting.
- Lab-grown diamonds: Known for classic diamond brilliance, with white light reflections and colourful fire.
Neither appearance is automatically better. The right choice depends on whether you prefer bold, colourful sparkle or traditional diamond brilliance.
Moissanite vs. Lab-Grown Diamonds: Comparison at a Glance
| Feature | Moissanite | Lab-Grown Diamond |
|---|---|---|
| Composition | Silicon carbide | Carbon |
| Gemstone Type | Distinct gemstone | Genuine diamond |
| Mohs Hardness | Approximately 9.25 | 10 |
| Brilliance | Bright, lively appearance | Classic diamond brilliance |
| Rainbow Fire | Generally more pronounced | Generally more restrained |
| Typical Price | Generally more affordable | Generally higher for comparable jewelry |

Actual appearance and pricing depend on the stone's cut, size, quality, metal, and setting.
Cost Comparison in Canada
Price matters, especially when choosing an engagement ring or a meaningful gift. Both moissanite and lab-grown diamonds can offer attractive alternatives to mined diamond jewelry, but their prices differ.
Which Gemstone Is More Affordable?
Moissanite is generally the more affordable choice when comparing jewelry of similar size and design. This can leave more room in your budget for a larger centre stone, a different metal, or matching jewelry.
Lab-grown diamonds typically cost more than moissanite, but prices vary considerably by carat weight, colour, clarity, cut, certification, and setting. They can also cost substantially less than comparable mined diamonds.
When comparing prices, make sure you're comparing similar jewelry. A ring with a Solid 14K Gold setting should not be compared directly with one featuring 18K Gold Plated 925 Silver without considering the metal difference.
Shopping tip: Compare the complete ring, including gemstone specifications, metal, certification, warranty, and shipping, rather than judging value by carat weight alone.
Sparkle and Light Performance
Moissanite Sparkle
Moissanite has a refractive index of approximately 2.65 to 2.69, compared with approximately 2.42 for diamond. Its greater light dispersion helps create the colourful rainbow flashes that make moissanite distinctive.
If you love jewelry that catches attention with vibrant flashes of colour, moissanite may be your favourite.
Lab-Grown Diamond Sparkle
Lab-grown diamonds have the same fundamental optical properties as mined diamonds. Their appearance combines white brilliance, fire, and scintillation, with the final result influenced by cut quality and proportions.
If you prefer the traditional look of a diamond engagement ring, a lab-grown diamond offers that experience because it is a genuine diamond.
Durability and Strength
Both gemstones are excellent choices for jewelry worn regularly.
| Feature | Moissanite | Lab-Grown Diamond |
|---|---|---|
| Mohs Hardness | Approximately 9.25 | 10 |
| Scratch Resistance | Excellent | Excellent |
| Daily Wear | Suitable with proper care | Suitable with proper care |
| Impact Damage | Possible | Possible |
Diamond ranks highest on the Mohs hardness scale, while moissanite is also exceptionally hard. However, hardness measures scratch resistance, not resistance to every type of damage. Either gemstone can chip under certain impacts, and the setting also requires care.
Appearance Over Time
Moissanite and lab-grown diamonds do not normally become cloudy simply because they age. Both can retain their beauty for many years.
Skin oils, lotions, soap residue, and everyday dirt can accumulate on jewelry and reduce its visible sparkle. Gentle cleaning using methods appropriate for the gemstone and metal finish can help restore its appearance.
Remember that gemstone durability and metal-finish durability are different. Gold-plated jewelry requires additional care to protect its finish.
Certification: GRA vs. IGI
Understanding the documentation accompanying your gemstone can help you shop with confidence.
MOISS & ICE Moissanite
MOISS & ICE uses premium D Colour, VVS moissanite. Eligible moissanite jewelry includes GRA documentation, and our moissanite passes a standard diamond tester. However, a diamond tester result does not make moissanite a diamond.
MOISS & ICE Lab-Grown Diamonds
Our lab-grown diamonds feature E Colour, VVS2 clarity, and IGI certification. An IGI report provides independent documentation of the diamond's assessed characteristics, helping buyers understand what they are purchasing.

Common Questions and Buying Concerns
“Are lab-grown diamonds real diamonds?”
Yes. Lab-grown diamonds are genuine diamonds. Their laboratory origin distinguishes them from mined diamonds, not their status as diamonds.
“Does moissanite look fake?”
Moissanite is a genuine gemstone with its own optical characteristics. Its colourful fire can look different from diamond, particularly in bright lighting. That distinctive sparkle is exactly what many buyers love about it.
“Do lab-grown diamonds have better resale value?”
Resale values vary widely for both gemstones and depend on market demand, the jewelry's condition, and other factors. Neither should be purchased with an expectation of recovering its original retail price.
For most customers, the more meaningful consideration is choosing jewelry they'll enjoy wearing.
Which Should You Choose?
Choose Moissanite If:
- You love bold rainbow sparkle and vibrant fire.
- You want a larger-looking gemstone while managing your budget.
- You appreciate moissanite as a distinctive gemstone.
- You want beautiful jewelry across rings, earrings, bracelets, and chains.
Choose Lab-Grown Diamonds If:
- You want a genuine diamond without choosing a mined diamond.
- You prefer classic diamond brilliance.
- You value E Colour, VVS2 clarity, and independent IGI certification.
- You want the traditional diamond experience in an engagement ring or other fine jewelry.
There is no wrong choice between two gemstones you genuinely love. The best choice is the one that matches your taste, priorities, and budget.
