Most advice on cleaning sterling silver assumes plain, unplated silver. If your jewellery is gold plated, rose gold plated or rhodium plated, some of those methods (silver dips, baking soda pastes, polishing compounds) can wear away the very finish you want to protect. And if the piece is set with a gemstone, the stone has its own needs. This guide gives you a gentle routine that works for plated 925 silver with gems, plus what to avoid.
Before you start: know what you are cleaning
Check three things:
- The metal. A 925 stamp means sterling silver. If it is yellow or pink in colour, it is plated with gold. If it is bright white, it may be rhodium plated.
- The stone. Hard stones such as sapphire, ruby and diamond tolerate more than soft or porous ones such as pearl, opal and emerald.
- The treatment. Emeralds are commonly oiled, and some stones are fracture-filled. Heat, solvents and ultrasonic vibration can affect these. Our treatment guide explains the common labels.
The gentle routine (works for almost everything)
You need: a small bowl of lukewarm water, a drop of mild, fragrance-free dish soap, a very soft toothbrush or makeup brush, and a lint-free microfibre cloth.
- Soak briefly. Place the piece in the soapy water for a few minutes. Skip this for pearls and opal; wipe them with a damp cloth instead.
- Brush lightly. Use the soft brush on the back of the setting and around the stone, where lotion and skin oils collect. That buildup is usually what makes a gemstone look dull.
- Rinse. Rinse in clean lukewarm water. Close the sink drain first.
- Dry completely. Pat dry with the microfibre cloth, then let it air-dry fully before storing. Trapped moisture speeds up tarnish.
This is close to what GIA recommends in its tips on caring for jewellery: warm, soapy water and a soft brush are the safest general method for most gem-set pieces.
What to avoid on plated silver
| Method | Plain sterling silver | Gold or rhodium plated silver |
|---|---|---|
| Warm water and mild soap | Safe | Safe |
| Plain microfibre cloth | Safe | Safe |
| Silver polishing cloth (with compound) | Safe | Use rarely; it can slowly wear plating |
| Silver dip solution | Use with care | Avoid; can strip or discolour plating and harm stones |
| Baking soda or toothpaste | Mildly abrasive | Avoid; abrasive on thin layers |
| Bleach, chlorine, ammonia | Avoid | Avoid |
| Ultrasonic cleaner | Depends on the stone | Avoid at home; vibration can loosen stones and stress plating |
| Steam cleaner | Depends on the stone | Avoid for emeralds, pearls, opal and treated stones |
Stone-by-stone notes
Sapphire and ruby
Both are corundum, rated 9 on the Mohs scale, and very durable. Warm soapy water is ideal. Stones with filled fractures (sometimes seen in lower-cost rubies) need extra gentleness: no heat, no ultrasonic.
Emerald
Most emeralds are treated with oil or resin to improve clarity, and this is normal. Hot water, steam, solvents and ultrasonic cleaners can draw out the oil. Use lukewarm soapy water, a quick rinse, and pat dry.
Pearl
Pearls are soft and sensitive to acids, perfume and soaking. Wipe with a soft, damp cloth after wearing and let them dry flat. Put pearls on last and take them off first.
Opal
Opal contains water and can be sensitive to sudden temperature changes. Wipe it gently and avoid soaking and heat.
Diamond, natural or lab-grown
Diamonds attract grease, which dulls their sparkle. Soapy water and a soft brush behind the stone bring the brightness back quickly.
Dealing with tarnish on plated pieces
Gold does not tarnish, and rhodium is very resistant. If you see dark patches on a plated piece, it usually means the plating has worn thin in that spot and the silver underneath is reacting with sulphur in the air. A gentle wipe with a plain cloth may lift light tarnish. Heavy rubbing will only remove more plating. If a favourite piece has lost its colour, ask a jeweller about re-plating: because the base is solid 925 silver, it can be refreshed in yellow gold, rose gold or rhodium.
Daily habits that save cleaning time
- Last on, first off. Put jewellery on after lotion, sunscreen, perfume and hairspray. Take it off before washing up, cleaning, swimming, showering or the gym.
- Wipe after wearing. Ten seconds with a soft cloth removes skin oils before they build up.
- Store separately. Keep each piece in its own pouch or a lined box compartment. Sapphires and diamonds are hard enough to scratch metal finishes and softer stones.
- Keep it dry. An airtight bag or a small anti-tarnish strip in your jewellery box slows tarnish on any exposed silver.
- Check settings. Every few months, look at the prongs with a loupe or ask a jeweller. A loose stone is easy to fix early.
Caring for Roho pieces
Our 925 silver gemstone jewellery, including the gemstone heart bracelets and zodiac birthstone necklaces, is solid sterling silver with nickel-free yellow gold, rose gold or white rhodium plating. Each order arrives with a pouch for storage, and the routine above is all it needs.

FAQ
Can I use a silver polishing cloth on gold-plated silver?
Occasionally and gently. Many polishing cloths contain a mild abrasive or chemical that removes tarnish by removing a tiny amount of surface. On plated pieces, a plain microfibre cloth is safer for regular use.
Can I wear gold-plated sterling silver in the shower?
It is best not to. Soap residue, hard water and heat dull the finish and speed up wear. Take it off before showering and swimming.
How often should I clean my jewellery?
Wipe after each wear and do the soapy-water routine every few weeks for pieces worn daily, or whenever a stone starts to look cloudy.
Is an ultrasonic cleaner safe for sapphire jewellery?
For untreated or heated sapphire in a solid gold setting, a professional ultrasonic clean is usually fine. For plated silver, fracture-filled stones, emeralds, pearls and opal, stick to warm soapy water.
