1. Composition and Origin
Moissanite is made of silicon carbide (SiC), originally discovered in a meteor crater. Today, it is lab-created, ensuring consistent quality and ethical sourcing.
Diamonds are pure carbon crystals formed deep within the Earth over billions of years. They can be natural or lab-grown, but natural diamonds remain rare and expensive.
2. Brilliance and Sparkle
- Diamond: Elegant, classic sparkle with subtle light reflection.
- Moissanite: Higher dispersion, producing more fire and rainbow brilliance.
Moissanite often appears more brilliant, especially under strong lighting conditions.
