Diamond vs Moissanite
Moissanite is not a fake diamond — it is a different gemstone with its own impressive properties. Here is the honest comparison.
The Bottom Line
If budget matters and you want maximum sparkle per dollar, moissanite wins easily. If you want the prestige, resale value, and subtle sparkle of a natural diamond, go diamond. Lab-grown diamonds are an excellent middle ground — real diamonds at 50–70% less.
Price
Edge: MoissaniteDIAMOND
Natural diamonds: $3,000–$10,000+ per carat. Lab-grown: $800–$2,000 per carat.
MOISSANITE
$400–$1,000 per carat. Dramatically less expensive than natural or lab-grown diamonds.
Brilliance (Sparkle)
Edge: Tie / preferenceDIAMOND
High brilliance — the classic sparkle that has defined fine jewelry for centuries. RI: 2.42.
MOISSANITE
Higher brilliance than diamond due to higher refractive index (RI: 2.65). Can look "too sparkly" under some lights.
Hardness
Edge: Diamond (slightly)DIAMOND
10/10 on the Mohs scale — the hardest natural material. Scratch resistant and incredibly durable.
MOISSANITE
9.25/10 on the Mohs scale. Extremely hard — second only to diamond. Suitable for everyday wear.
Ethics
Edge: MoissaniteDIAMOND
Natural diamonds: complex supply chains with some ethical concerns. Lab-grown: conflict-free, environmentally cleaner.
MOISSANITE
Lab-created only. No mining. Consistently ethical and environmentally responsible.
Prestige
Edge: DiamondDIAMOND
Universally recognized as the ultimate engagement ring stone. Significant cultural and emotional weight.
MOISSANITE
Growing acceptance, but lacks the prestige and cultural recognition of diamonds.
Resale Value
Edge: DiamondDIAMOND
Natural diamonds hold value. Lab-grown resale is lower but improving.
MOISSANITE
Very low resale value — moissanite is valued for wear, not investment.
