Diamond vs. Moissanite: What's the Difference?

Diamond vs. Moissanite: An Honest Comparison of Two Gemstones

Moissanite vs. Diamond – in 2026, this is one of the most debated questions in the engagement ring world. Moissanite has established itself as a serious alternative. We compare them objectively.

What is Moissanite?

Moissanite is silicon carbide (SiC) – originally discovered in a meteorite (1893, by Henri Moissan). Natural moissanite is extremely rare; today, moissanite is almost exclusively produced in laboratories. It is not a diamond imitation, but a gemstone in its own right.

Optical Comparison

• Brilliance: Moissanite refracts light more strongly than diamond – it is even "sparklier"
• Fire (Rainbow Effect): Moissanite shows more play of color than diamond – some love it, others find it "unnatural"
• Color: Moissanite can appear slightly grayish or greenish in strong light

Physical Comparison

• Hardness: Diamond Mohs 10 (hardest known substance), Moissanite Mohs 9.25 – also extremely hard
• Durability: Both are very suitable for daily wear

Price

• 1 Carat Diamond (G/VS1, Brilliant Cut): approx. €4,000–€7,000
• 1 Carat Moissanite: approx. €300–€600

Who is each suitable for?

• Diamond: For tradition, emotional value, status symbol, resale value
• Moissanite: For size on a budget, sustainability awareness, ethical convictions
