How to clean gold and diamond jewellery at home
The short version#
Warm water, a drop of plain dish soap, a soft toothbrush. That is the whole method for gold and diamonds.
Never use toothpaste, baking soda, bleach or an ultrasonic cleaner at home.
Emeralds, opals, pearls and any glued setting must not be soaked at all.
Take the piece off before swimming, showering, gardening or applying perfume.
What you need#
Four things, all of which you already own: a small bowl, warm water — comfortable to the hand, not hot — one drop of unscented dish soap, and a baby toothbrush with soft bristles. That is the entire kit. The bottles sold as jewellery cleaner are mostly the same soap at forty times the price.
How to clean a diamond ring at home#
Soak the ring in the warm soapy water for fifteen minutes. This loosens the film of hand cream, soap residue and skin oil that dulls a diamond far more than any scratch. Brush gently, paying attention to the underside of the stone — that is where the film collects and where light enters. Rinse in clean warm water and dry with a lint-free cloth.
Do it over a bowl, never over an open drain. Every jeweller has the same story about a ring and a plughole.
Why the underside matters most#
A diamond's brilliance comes from light entering the top, bouncing off the back facets and returning to your eye. A greasy film on the underside stops that light returning, which is why a dirty diamond looks grey rather than dirty. Clean the back and the stone appears to brighten dramatically — nothing has changed except the light path.
What you must never use#
Toothpaste is abrasive and will scratch gold, dulling a polished surface permanently. Baking soda does the same. Bleach and chlorine attack the alloy metals in gold and can cause a claw to fail without warning. Ultrasonic cleaners are excellent in a workshop and dangerous at home: the vibration can loosen a stone that was already slightly insecure, and you will not know until it falls out.
Which stones must not be soaked?#
Emeralds are almost always oil-treated, and soaking strips the oil, leaving internal fractures visible. Opals contain water and can craze. Pearls are organic and soap dissolves their lustre. Turquoise and coral are porous. For any of these: wipe with a barely damp soft cloth and stop there. Anything glued rather than set in claws should also stay dry.
How often should you clean jewellery?#
A ring worn daily benefits from a soak every two weeks. Earrings and pendants, which touch skin less, are fine monthly. Beyond that, once a year bring the piece to a jeweller — not for cleaning but for a claw check under magnification. A loose claw is silent, cheap to fix, and expensive to ignore.

Conclusion: the habit that matters most#
Cleaning helps, but taking the piece off helps more. Chlorine, sea salt, gardening grit, perfume and hairspray do more damage in a year than a decade of ordinary wear. Make a habit of removing rings before water and before scent, and the fortnightly soak becomes a small pleasure rather than a rescue operation.Storing jewellery so it stays clean
Most damage happens in the box, not on the hand. Pieces stored loose together scratch each other — a diamond will scratch gold, and it will scratch another diamond. Keep each piece in its own soft pouch or a lined compartment, and never let chains sit in a heap, because a knotted fine chain often cannot be saved.
Silver needs one extra thing: air kept out. A sealed bag slows tarnish considerably, and a strip of anti-tarnish paper slows it further. Gold does not tarnish, so it only needs protecting from scratches.
When to stop and call a jeweller#
Four signs mean the piece should not be cleaned at home, and should be looked at instead. If you can hear a faint rattle when you shake the piece near your ear, a stone is loose. If a claw catches on fabric, it has lifted. If the band has gone noticeably thin on the underside, it is wearing through. If a stone looks cloudy from the inside rather than the surface, cleaning will not touch it.
None of these is an emergency, and all four are cheaper to fix early. A lifted claw costs very little to re-tip. A lost stone costs whatever the stone cost.
