Key Differences Explained Between Diamond and Moissanite
Composition and Structure
Diamonds are formed from carbon under extreme pressure deep inside Earth or in advanced laboratories. Moissanite is made from silicon carbide and is usually lab created.
This structural difference affects sparkle, hardness, and pricing.
Sparkle and Brilliance
One of the biggest differences is how the stones reflect light.
- Diamonds produce more white light brilliance
- Moissanite creates stronger rainbow colored flashes called “fire”
Real life example:
Under jewelry store lighting, moissanite often appears more colorful and flashy than diamonds.
Price Difference
Moissanite costs significantly less than diamonds of similar size and appearance.
For example:
- A one carat diamond may cost thousands of dollars
- A similar moissanite stone can cost a fraction of that amount
This makes moissanite popular among budget conscious buyers.
Hardness and Durability
Diamonds are the hardest natural substance on Earth.
10 > 9.25
On the Mohs hardness scale:
- Diamond = 10
- Moissanite = approximately 9.25
Both are highly durable for daily wear, but diamonds resist scratches slightly better.
Resale and Long Term Value
Diamonds usually retain stronger resale and luxury market recognition. Moissanite generally has lower resale demand because it is mass produced.
Ethical and Environmental Considerations
Many modern buyers prefer lab created stones due to environmental and ethical concerns associated with mining.
Companies like De Beers and modern lab grown jewelry brands increasingly promote sustainable gemstone options.
