Understanding the differences between lab-grown diamonds and Moissanite is crucial for anyone looking for a sustainable and ethical alternative to natural diamonds. These two gemstones are often compared for their brilliance, affordability, and ethical appeal. So, what sets them apart, and which one is the right choice for you?
Introduction
The modern jewelry market has evolved, offering eco-conscious and budget-friendly options without compromising on beauty. Among these alternatives, lab-grown diamonds and Moissanite jewelry stand out.
Though similar in appearance, they differ in composition, value, and characteristics. This comparison unpacks their unique features to help you make an informed decision.

What is Moissanite?
Moissanite is a gemstone made of silicon carbide (SiC). Initially discovered in meteorites, it is now lab-created to offer brilliance comparable to diamonds, though with distinct differences.
Unique Properties of Moissanite
- Exceptional fire and brilliance.
- Remarkable durability with a Mohs hardness of 9.25.
- Eco-friendly and highly affordable.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds created in controlled environments, replicating the natural process through advanced technology. They share the same chemical, physical, and optical properties as mined diamonds but are produced ethically.
How Are They Made?
- High-Pressure High-Temperature (HPHT): Simulates the Earth's natural diamond-forming conditions.
- Chemical Vapor Deposition (CVD): Utilizes carbon-rich gas to grow diamond layer by layer.
These processes ensure lab-grown diamonds are virtually indistinguishable from mined ones.
Lab-Grown Diamonds vs. Moissanite: Key Differences
Let’s explore the main distinctions between these two popular alternatives:
| Feature | Moissanite | Lab-Grown Diamond |
|---|---|---|
| Origin | Lab-created (originally discovered in meteorites) | Lab-created (synthetic version of natural diamond) |
| Chemical Composition | Silicon Carbide (SiC) | Carbon (C) |
| Crystal Structure | Hexagonal | Cubic (same as natural diamond) |
| Hardness (Mohs Scale) | 9.25 | 10 |
| Durability | Extremely durable but slightly less than diamond | Very durable – identical to a natural diamond |
| Brilliance (Sparkle) | More brilliance, fiery (rainbow sparkle) | More subtle brilliance, white sparkle (same as natural) |
| Refractive Index | 2.65 – 2.69 (double refractive) | 2.42 (single refractive) |
| Dispersion (Fire) | 0.104 (more fire) | 0.044 (less fire) |
| Density / Specific Gravity | ~3.2 | ~3.5 |
| Color | Typically near-colorless, but warmer tones; color grading is different | Can be colorless or graded like natural diamonds (D-Z scale) |
| Clarity | Usually very high clarity; fewer inclusions | Varies widely; graded like natural diamonds |
| Cost | Much cheaper (up to 90% less than a mined diamond) | Less expensive than a natural diamond but costlier than moissanite |
| Visual Differences | More rainbow-like sparkle; a trained eye can tell | Indistinguishable from a natural diamond without specialized equipment |
| Heat Resistance | Can withstand high temperatures but less than diamonds | Extremely heat resistant (same as natural diamond) |
| Electrical Conductivity | Semiconductor | Insulator (Type Ia) or conductor (Type IIb), depending on type |
| Fluorescence | May show fluorescence under UV | May or may not show fluorescence; graded like mined diamonds |
| Ethical Consideration | Conflict-free; eco-friendly | Conflict-free; eco-friendly |
| Resale Value | Low resale value; not seen as an investment | Has resale value, but generally lower than a natural diamond |
| Customization & Cuts | Available in all standard cuts | Available in all standard cuts |
| Use in Jewelry | Common for engagement rings, earrings, and fashion jewelry | Common for engagement rings and high-end jewelry |
| Popularity | Gaining popularity for affordability and sparkle | Increasingly popular due to ethical sourcing and identical properties to natural diamonds |
| Magnetism | Non-magnetic | Non-magnetic (some may have impurities) |
Durability: Which One Lasts Longer?
Durability is a major factor when choosing between lab-grown diamonds and Moissanite. Lab-grown diamonds, being pure carbon, are the hardest known substance with unmatched scratch resistance. Meanwhile, Moissanite is also incredibly durable and suitable for everyday wear, but it is slightly softer.
Verdict
For those seeking maximum longevity, lab-grown diamonds take the lead. However, Moissanite offers a close second with sufficient durability for lifetime use.

Brilliance and Sparkle: Which Shines Brighter?
While both gemstones are undeniably stunning, their sparkle differs.
- Lab-Grown Diamonds: Exhibit the natural brilliance associated with traditional diamonds, reflecting white light for a classic sparkle.
- Moissanite: Offers higher refractive index, resulting in a "rainbow effect," which some may find overly flashy.
Verdict
Choose lab-grown diamonds for timeless elegance or Moissanite for a bold, eye-catching shimmer.
Affordability: How Do They Compare?
Affordability is often a deciding factor.
- Lab-Grown Diamonds: Typically 20-40% cheaper than mined diamonds but more expensive than Moissanite.
- Moissanite: Costs significantly less, making it ideal for budget-conscious buyers.
Verdict
If affordability is your priority, Moissanite wins hands down. For those desiring a genuine diamond within a moderate budget, lab-grown diamonds are an excellent choice.

Ethical and Environmental Considerations
Both lab-grown diamonds and Moissanite are celebrated for their ethical production and minimal environmental impact.
Unlike mined diamonds, which can have a history of conflict and ecological damage, these alternatives represent conscious consumerism.
Color and Clarity Options
Color and clarity are vital aspects when selecting a gemstone.
- Lab-Grown Diamonds: Available in colorless and near-colorless options, mimicking the highest grades of natural diamonds.
- Moissanite: Almost always colorless, but under certain lights, it may exhibit a slight grayish or yellow tint.
Which One Should You Choose?
Your choice depends on personal preferences and priorities.
- Choose Lab-Grown Diamonds if you value authenticity, timelessness, and unparalleled durability.
- Choose Moissanite for a more affordable yet dazzling option, perfect for bold and vibrant styles.

FAQs
1. Are lab diamonds or Moissanite better?
Lab diamonds and Moissanite both have their benefits. Lab diamonds are chemically identical to natural diamonds, while Moissanite is a more affordable, durable, and sparkly alternative.
2. Is Moissanite a fake diamond?
No, Moissanite is a real gemstone, just not a diamond. It has its own unique properties and isn’t a "fake" diamond but an alternative.
3. Can a jeweler tell the difference between Moissanite and diamond?
Yes, jewelers can usually tell the difference, especially with specialized tools, since Moissanite has a different refractive index and heat conductivity than diamonds.
4. Is it better to buy a diamond or a Moissanite?
It depends on your preference and budget. Diamonds are natural and hold more value, while Moissanite is more affordable and has more sparkle.
5. Does Moissanite beat a diamond tester?
Moissanite may pass some diamond testers that check for conductivity, as it is a good heat conductor, but it’s not the same as a diamond and may not pass all tests.
6. How much is a 1 carat lab diamond vs 1 carat Moissanite?
A 1-carat lab diamond usually costs around $1,000 to $2,000, while a 1-carat moissanite costs about $300 to $600. Choose a lab diamond for authenticity or moissanite for a budget-friendly, sparkly alternative.
7. How to know the Difference Between Moissanite and Lab Diamond?
Moissanite and lab-grown diamonds look similar but differ in composition and brilliance. Moissanite is made of silicon carbide and has more rainbow sparkle, while lab diamonds are real diamonds created in a lab and have the same chemical makeup as natural diamonds. A diamond tester can tell them apart; moissanite may not test as a diamond.
8. How should you choose between moissanite and lab-grown diamonds?
Choose moissanite if you want a more affordable, extra-sparkly gem that's durable and beautiful. Pick a lab-grown diamond if you want a genuine diamond with traditional brilliance, higher value, and better resale potential.
9. Where can you buy a moissanite engagement ring?
