How to Clean Diamond Jewellery at Home (and What Never to Use)
Ten minutes, warm water, a drop of washing-up liquid and a soft brush: the safe way to bring back your diamonds' sparkle, plus the household "hacks" that do real damage.
Diamonds do not get dirty so much as greasy. Skin oils, moisturiser, sunscreen and soap cling to the stone, and an oily film stops light entering and leaving it, so even a beautifully cut diamond looks dull. The fix takes ten minutes and things you already have at home.
The ten-minute clean
- Make a gentle bath. Fill a small bowl with warm (not hot) water and add a few drops of mild washing-up liquid.
- Soak. Leave rings, studs or bracelets in the bath for 20 to 30 minutes to loosen the build-up.
- Brush. Use a soft baby toothbrush to clean gently around and behind each stone, where grime collects.
- Rinse. Rinse under warm running water, over a bowl or with the plug in. Every jeweller has heard a story about a ring and a drain.
- Dry. Pat dry with a lint-free or microfibre cloth. Avoid paper towels, which can scratch gold.
What never to use
Social media is full of "hacks" that damage jewellery. Toothpaste and baking soda are abrasive and leave fine scratches on gold and platinum. Bleach and chlorine can weaken gold alloys over time, which is why you should take rings off before a swim in a chlorinated pool or a spa. Acetone and strong household cleaners can damage other gemstones and the finish of plated metal.
Are ultrasonic cleaners safe?
For solid gold set with diamonds alone, usually yes. But ultrasonic vibrations can loosen stones in worn settings, and they are not suitable for many coloured gemstones or for pieces with glued or fragile parts. If in doubt, stick to the soak and brush, and let a jeweller use professional equipment.
How often to clean
| Piece | Clean at home | Professional check |
|---|---|---|
| Engagement ring worn daily | Weekly or fortnightly | Every 6–12 months |
| Earrings and pendants | Monthly | Yearly |
| Tennis bracelet | Monthly | Yearly (clasp and links) |
When to see a jeweller
- A stone moves, rattles or sits crooked
- A prong catches on clothing or looks flat and thin
- White gold looks yellowish (time for rhodium plating)
- A clasp no longer closes firmly

Cleaning different pieces
Rings
Grime collects under the centre stone and inside the basket. Brush from the side and underneath, not just across the top.
Stud earrings
Clean the posts and backs as well as the diamonds: backs collect skin oils and can loosen their grip. Wipe posts with a little rubbing alcohol on a cotton pad.
Tennis bracelets
Soak, then brush gently along the line with the bracelet laid flat. Never tug the links while they are wet and soapy.
Pendants and chains
Soak the pendant and chain together, then pull the chain gently through a soft cloth. Fasten it before drying so it does not tangle.
Gold, white gold and silver: what changes
The same gentle soap bath suits yellow, rose and white gold. White gold is usually rhodium plated, so avoid scrubbing it hard: the plating is thin and abrasive cloths wear it faster. Sterling silver can tarnish; after cleaning the diamonds, use a dedicated silver polishing cloth on the metal only, and keep it away from other gemstones.
What a professional clean adds
A jeweller can do what you cannot at home: steam-clean packed dirt from settings, polish out fine scratches, and, most importantly, inspect prongs, beads and clasps under magnification. Ask for the inspection even if the piece looks clean; worn prongs rarely look worn until a stone is loose.
Made to sparkle for decades
Can I clean a lab-grown diamond the same way?
Yes. Lab-grown diamonds are real diamonds and need exactly the same care.
Does vinegar clean diamonds?
It will cut through grease, but it is acidic and not kind to some metals and gemstones. Mild washing-up liquid works just as well and is safer.
Why does my ring look cloudy right after cleaning?
Usually soap residue or water spots. Rinse well in clean warm water and dry with a lint-free cloth.
Can I use a jewellery polishing cloth on my diamond ring?
Yes on gold, gently. Avoid silver cloths on white gold, and avoid any cloth that leaves a residue on the diamond; rinse and dry afterwards if it does.
Is rubbing alcohol safe for diamonds?
A quick wipe with isopropyl alcohol is fine for diamonds set in gold, and handy for earring posts. Avoid it on pearls, opals, emeralds and other porous or treated gemstones.
