Some jewelry dulls over time.
Moissanite never loses its sparkle.

Yes — our moissanite pieces are built for daily wear. Showering, washing hands, and everyday activity won't affect them.

Moissanite's diamond-grade hardness means it won't scratch or dull over time, and our 18k gold and rhodium vermeil settings are plated five times thicker than standard. Avoid prolonged soaking in chlorinated or salt water, which can affect the metal over time.

Yes — moissanite is a genuine gemstone, not glass and not cubic zirconia. It was first discovered in a meteor crater, and the moissanite used in jewelry today is lab-grown to the same chemical composition as the natural stone. It's its own stone with its own properties — and in several measurable ways, it outperforms diamond.

No — this is what sets moissanite apart. Unlike cubic zirconia, which hazes over time, moissanite is chemically stable. Its sparkle is structural, not surface-level, so daily wear won't dull it. The stone you receive will look identical in ten years.

In hardness, moissanite ranks 9.25 on the Mohs scale — second only to diamond at 10. In brilliance and fire, it actually exceeds diamond, producing more light return and the rainbow flashes moissanite is known for. Our white moissanites are graded D colour, VVS1 clarity — the same standard used for the finest diamonds. Coloured moissanites are plated over the same high-quality D/VVS1 white stones. The difference from diamond is origin and price, not quality.

Every Mondays Made piece comes with a 2-year warranty. If a stone loosens, a clasp breaks, or anything isn't right, contact us and we'll make it right. Returns are accepted within 30 days of delivery, no questions asked.

Yes. All our pieces are hypoallergenic and nickel-free. The base is S925 sterling silver — one of the safest metals for sensitive skin — finished in either 18k gold vermeil or rhodium vermeil. If you have a severe metal sensitivity, we'd recommend the rhodium finish specifically — rhodium is one of the most unreactive metals available, making it the gentlest option for skin.
