Moissanite vs Diamond: Honest 2026 Guide

By Sophia Rivera · October 8, 2026

Two Popular Engagement Ring Stones Compared

Choosing between moissanite and diamond remains one of the most common engagement ring decisions in 2026. Both offer beauty and durability, but differ in key ways.

Brilliance and Fire

Moissanite has a higher refractive index than diamond, producing more intense rainbow-colored flashes called fire. Some love this extra sparkle while others prefer the subtle brilliance of diamond.

Hardness and Daily Wear

Diamond scores 10 on the Mohs scale while moissanite scores 9.25. Both are extremely durable for daily wear, making either a practical long-term choice for an engagement ring.

Price Difference

A one-carat moissanite costs 80-90% less than a comparable diamond. This savings can go toward a larger stone, a more elaborate setting, or other wedding expenses.
