How to Care for Moissanite Jewellery: Does It Get Cloudy?

One of moissanite's biggest selling points is how little it asks of you. It is a gemstone in its own right — silicon carbide, first discovered in a meteorite crater and now lab-created — and at 9.25 on the Mohs scale it is harder than sapphire, ruby and every other gem except diamond. Here is the full care routine, and the honest answer to the question everyone asks.

Does moissanite get cloudy over time?

No — not permanently. Moissanite itself is chemically stable and does not degrade, yellow or fog with age. What people describe as "cloudiness" is a surface film of skin oils, soap residue and hand cream, exactly the same film that dulls diamonds. It sits on the stone, not in it, and a proper clean restores the full fire every time. If your moissanite looks dull, it needs a bath — nothing more.

How do you clean moissanite jewellery at home?

Warm water, a few drops of washing-up liquid, a 20-minute soak and a gentle going-over with a soft toothbrush — pay attention to the underside of the stone, where films build up fastest. Rinse and dry with a lint-free cloth. Every few weeks is plenty for a daily-wear ring. Moissanite is also heat-resistant and tough, so it tolerates careful cleaning better than most gems — but the setting is usually the limiting factor, which brings us to the next point.

Do you need to care for the setting differently to the stone?

Yes — and with moissanite the setting is nearly always the more delicate part. Our moissanite pieces are set in 925 sterling silver, which can tarnish where the stone cannot. Keep the piece away from chlorine, sulphur-rich environments (hot springs, some spa pools) and household cleaning chemicals, and wipe the metal with a soft cloth after wear. If the silver dulls, our guide to why sterling silver tarnishes and how to fix it covers the rescue routine.

Can moissanite scratch or chip?

It is extremely difficult to scratch — in practice only diamond and another moissanite will do it. But like diamond, hardness is not invincibility: a hard knock on a sharp corner can chip any gemstone, so take rings off for the gym, gardening and anything involving impact. Moissanite's toughness rating is actually excellent, making it one of the most durable choices for daily wear.

How should you store moissanite jewellery?

Do Don't
Give each piece its own pouch or compartment — moissanite scratches softer gems and metals Store it loose against other jewellery
Use an airtight bag or anti-tarnish strip to protect the silver setting Keep it in a humid bathroom
Fasten clasps and lay pieces flat Leave it in direct contact with rubber or newspaper, which accelerate silver tarnish

Which moissanite pieces are easiest to live with?

Studs and pendants collect less grime than rings simply because your hands touch them less — the Rainbow Moissanite Studs and Moissanite Teardrop Pendant can go months between cleans. Statement rings like the Blue Moissanite Butterfly Ring reward a quick fortnightly bath. Browse the full Moissanite Collection here.
