Gemstone Comparison

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: Moissanite

DIAMOND

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 / preference

DIAMOND

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: Moissanite

DIAMOND

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: Diamond

DIAMOND

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: Diamond

DIAMOND

Natural diamonds hold value. Lab-grown resale is lower but improving.

MOISSANITE

Very low resale value — moissanite is valued for wear, not investment.
