What Counts as a โReal Diamondโ?
Before comparing affordability, itโs important to distinguish what is considered a real diamond:
-
Natural Diamonds
Formed underground over billions of years; always considered real diamond. -
Lab-Grown Diamonds
Created in controlled laboratories but identical in chemical structure and sparkle to natural diamonds.
โ Scientifically real diamonds
โ Certified and graded the same way as natural diamonds -
Moissanite
Not a diamond. It is a lab-created gemstone with higher brilliance but a different chemical composition.
โ Beautiful and durable
โ Popular as a diamond alternative, not a diamond

Lab-Grown Diamond vs. Natural Diamond vs. Moissanite
Below is a clean, objective comparison that helps you see how these three stones differ:
| Feature | Natural Diamond | Lab-Grown Diamond | Moissanite |
|---|---|---|---|
| Composition | Carbon | Carbon | Silicon Carbide |
| Hardness (Mohs) | 10 | 10 | 9.25 |
| Sparkle | Classic diamond fire | Identical to natural | Very fiery, rainbow flashes |
| Price | Highest | 50โ80% less than natural | Lowest |
| Long-Term Value | Strong resale value | Lower resale value | Minimal resale value |
| Ethics / Sustainability | Depends on mining source | Eco-friendly & conflict-free | Eco-friendly |
| Appearance | Timeless | Same as natural | Slightly warmer flashes |
| Best For | Tradition seekers | Affordable real diamond | Budget-focused buyers seeking alternatives |
When considering affordability, the cost gap is the most significant:
-
Natural diamonds remain the most expensive due to rarity and mining costs.
-
Lab-grown diamonds offer the best affordability for those wanting a real diamond.
-
Moissanite is the most budget-friendly option, but it should be considered a diamond alternative, not a diamond engagement ring.
This is why lab-grown diamonds dominate todayโs affordable diamond engagement ring market.ย

All three gemstones offer excellent brilliance, but their visual effects and light refraction methods differ.
Natural Diamond: Known for its classic, deep white light and fire. Cut quality is the critical factor determining its sparkle. Goal: Seeking traditional and classic sparkle.
Lab-Grown Diamond: Visually identical to a natural diamond, offering the same classic fire. For the same budget, you can afford higher grades of cut and clarity, resulting in more stable, brilliant light. Goal: Seeking identical appearance with superior quality and size.
Moissanite: Has the highest “rainbow fire” (light dispersion). It reflects more rainbow light than diamond, creating a very intense and eye-catching visual effect. Goal: Seeking extreme sparkle/fire.
