Moissanite ranks at 9.25 on the Mohs hardness scale, just below diamonds (10), making it incredibly tough and scratch-resistant. It's ideal for everyday wear and tear.

So if you want a no-fuss, sparkle-all-day ring, Moissanite rings might edge ahead.

White sapphires tend to have a milky or cloudy appearance, especially when viewed in direct light. This can either be a drawback or a design feature, depending on your personal taste. They look especially stunning in vintage settings or paired with blue sapphire rings for a royal touch.
Moissanite, meanwhile, is often colorless (graded D–F) and clear, giving it that classic “diamond” appeal. The most popular cuts for both stones include round, oval, cushion, and princess, depending on your preferred ring style.
