When choosing a gemstone for jewelry, especially engagement rings or fine pieces, two popular options stand out: lab grown diamonds and moissanite.
Both offer beauty, affordability, and modern appeal—but they are not the same.
So, which one is better for your needs?
In this guide, we compare lab grown diamonds vs moissanite based on price, durability, appearance, and value—especially for buyers in the USA and UK.
What Are Lab Grown Diamonds?
Lab grown diamonds are real diamonds created in advanced laboratories using technologies like HPHT and CVD.
They have:
- The same chemical composition as natural diamonds
- The same hardness (10 on Mohs scale)
- The same brilliance and sparkle

What Is Moissanite?
Moissanite is a diamond alternative, not a real diamond. It is made from silicon carbide and is created in labs.
While it looks similar to diamonds, it has different properties:
- Slightly different sparkle (more rainbow effect)
- Lower hardness than diamonds
- More affordable
Lab Grown Diamonds vs Moissanite: Key Differences
| Feature | Lab Grown Diamonds | Moissanite |
|---|---|---|
| Composition | Real diamond (carbon) | Silicon carbide |
| Hardness | 10 (very durable) | 9.25 |
| Sparkle | Natural diamond brilliance | More rainbow sparkle |
| Price | Moderate | Lower |
| Certification | GIA / IGI | Limited |
| Resale Value | Higher | Lower |
1. Appearance & Sparkle
Lab grown diamonds look exactly like natural diamonds. They have a balanced brilliance and are indistinguishable to the naked eye.
Moissanite, on the other hand, has a more colorful sparkle, which some buyers love but others find less natural.
If you want a traditional diamond look, lab grown diamonds are better.
2. Durability & Hardness
Diamonds are the hardest known material, making lab grown diamonds extremely durable for everyday wear.
Moissanite is also durable but slightly softer.
For long-term jewelry like engagement rings, lab grown diamonds are the safer choice.
3. Price Comparison
Moissanite is cheaper than lab grown diamonds, making it ideal for budget buyers.
However:
- Lab grown diamonds offer better value
- They are still much cheaper than natural diamonds

- GIA
- IGI
This gives buyers confidence in quality.
Moissanite typically has less standardized certification.
