Is Moissanite a Real Diamond? Everything You Need to Know
If you’re shopping for engagement rings or fine jewelry, you might have wondered: “Is moissanite a real diamond?” (Learn more about moissanite vs diamonds). While moissanite can look similar to diamonds, it’s actually a distinct gemstone with its own unique properties. In this guide, we’ll explore the differences, similarities, and everything you need to know about moissanite.
What Is Moissanite?
Moissanite is a naturally occurring mineral made of silicon carbide (Read about what a moissanite stone is made of). It was discovered in 1893 by French chemist Henri Moissan in a meteorite crater, which is why it carries his name. Today, nearly all moissanite used in jewelry is lab-created, providing consistent quality, ethical sourcing, and environmental friendliness (Learn more about moissanite).
Unlike diamonds, which are pure carbon, moissanite has a different crystal structure. This structure gives it extraordinary brilliance (Why is moissanite so sparkly?), durability, and a unique sparkle that often displays rainbow-like flashes in sunlight.
Is Moissanite a Real Diamond?
The short answer is no—moissanite is not a diamond (Is moissanite a real diamond?). However, it is often used as a diamond alternative because of its appearance and durability. Here are the key distinctions:
Composition
Diamond: Pure carbon
Moissanite: Silicon carbide
Hardness
Diamond: Mohs scale 10
Moissanite: Mohs scale 9.25 (Moissanite hardness explained) (still extremely durable)
Brilliance
Moissanite actually has a higher refractive index than diamonds, meaning it can sparkle even more, with noticeable rainbow flashes (Learn about moissanite sparkle).
Price
Moissanite is typically much more affordable (Moissanite cost guide) than diamonds of the same size, making it an attractive choice for budget-conscious buyers.
Ethical Considerations
Since moissanite is lab-grown, it avoids the ethical and environmental concerns sometimes associated with diamond mining (Is moissanite ethical?, Is moissanite conflict free?).

| Composition | Carbon | Silicon carbide |
| Hardness (Mohs) | 10 | 9.25 |
| Brilliance | High | Higher, with rainbow flashes |
| Price | Expensive | Affordable |
| Ethical Sourcing | Mining required | Lab-created |
Why Choose Moissanite?
