Moissanite vs Diamond: How to Choose (Fire/Hardness/Budget)

Moissanite and diamond look similar, yet differ in brilliance, hardness, budget and sourcing. Here’s a simple comparison and buying advice by scenario.

1) What Are They?

  • Moissanite: Lab-grown silicon carbide known for high dispersion (fire).

  • Diamond: Naturally formed carbon crystal—classic and often chosen for engagements.

2) Key Differences (Plain English)

  • Brilliance/Fire: Moissanite shows stronger rainbow fire; diamond looks crisper/whiter;

  • Hardness/Durability: Diamond 10 on Mohs; moissanite ~9.25—both suitable for daily wear;

  • Weight/Size: Moissanite is slightly less dense, feeling lighter at the same size;

  • Budget: Moissanite offers larger looks for less; diamond pricing varies widely by 4Cs;

  • Certificates/Ethics: Moissanite often comes with maker/3rd-party reports; diamonds commonly with GIA/IGI; both can be sourced responsibly.

3) What to Choose by Scenario

  • Everyday/Office: Moissanite for value and sparkle;

  • Engagement/Anniversary: Choose diamond for tradition/symbolism, or moissanite for best value;

  • Sensitive Skin: Prefer sterling silver/gold/platinum settings.

4) FAQs

  • Does moissanite yellow? Not under normal wear; keep it clean for long-lasting brilliance.

  • Can people tell the difference? Hard at a glance; professionals use characteristic clues.

  • Resale value? Diamond resales are more established; moissanite value lies in the piece and brand service.
