The fastest way to keep pearls shiny is simple: put them on last, take them off first, and wipe them with a soft cloth after every wear. GIA and AGTA both build their care guidance around this habit, and we see the same pattern across the jewelry we carry at SuperJeweler. Get this one routine right and you’ll avoid most of the damage that dulls pearls over time.
TL;DR:
- Pearls have Mohs hardness of about 2.5, so store each piece in a soft pouch away from metal, harder gems, heat, and sealed plastic.
- For visible film, use warm water and mild fragrance free soap; never use ultrasonic or steam cleaners, bleach, peroxide, or abrasive cleaners.
- Treated, dyed, or coated pearls may react even to mild soap, so confirm treatment details with the seller and use only a dry cloth until then.
- Frequently worn strands need restringing about every two years, or sooner if the thread stretches, darkens, or frays; knots reduce pearl rubbing and loss.

What Actually Damages Pearls
Pearls are soft compared to most gemstones you wear alongside them. Their Mohs hardness sits around 2.5, well below a diamond or sapphire, which means the metal clasps, rough plastics, and even other jewelry pieces in your drawer can scratch the nacre surface before you notice anything is wrong.
A pearl’s Mohs hardness of about 2.5 makes it one of the more fragile materials in everyday jewelry, according to GIA, so storing pearls loose against harder stones or metal is a common way they pick up fine scratches.
Nacre itself is layered calcium carbonate, built up by the oyster coat after coat. That composition is why acids and harsh chemicals eat into the surface rather than just sitting on top of it, as the Smithsonian explains in its overview of how pearls form. Three categories of damage show up again and again:
- Abrasion: contact with metal, hard gemstones, or rough fabric wears down the nacre’s smooth surface.
- Chemicals: perfume, hairspray, cosmetics, ammonia, chlorine, and household cleaners break down the organic layers.
- Heat and dehydration: direct sun, dry storage, or prolonged heat can dry out nacre and cause discoloration or a chalky surface change.
None of these hazards require unusual conditions. They happen during a normal morning routine or a weekend by the pool, which is exactly why the daily habits in the next section matter so much.
Daily Care: The Soft Cloth Routine
The single habit that protects pearls more than anything else is sequencing: pearls go on after you’ve finished with perfume, hairspray, and makeup, and come off before you shower, clean the house, or exercise. GIA’s travel guidance frames this as “on last, off first,” and it’s the easiest rule to build into a routine because it asks nothing extra of you beyond reordering steps you already do.
Follow this sequence most days:
- Finish your skincare, makeup, and any fragrance or hairspray, and let everything dry completely.
- Put your pearls on as the last step before you leave the house.
- At the end of the day, remove your pearls before washing your face or getting into bed.
- Wipe the strand or piece gently with a soft, clean cloth, dry or very slightly damp, to lift off any residue from skin oils or light perfume drift.
- Lay the piece flat to air dry for a few minutes before putting it away.
A microfiber cloth or a piece of soft cotton works well. Avoid anything textured or anything that was used with cleaning solutions.
Pro Tip: Keep a small soft cloth in your jewelry box specifically for pearls so you’re never tempted to grab a rougher cloth or tissue in a hurry.
A quick wipe is enough for the vast majority of wears. Reach for a deeper clean only when pearls look visibly dull or have picked up a film you can’t remove with a dry or damp cloth, which is covered next.
Safe Deep Cleaning and What to Avoid
When a wipe isn’t enough, GIA and AGTA both point to the same gentle method rather than anything stronger. Here’s how to do it safely:
- Fill a small bowl with warm water and a drop of mild, fragrance-free soap.
- Dip a very soft cloth or soft-bristled brush, like a baby toothbrush, into the solution.
- Gently wipe or brush each pearl, avoiding the drill holes and any glued settings.
- Rinse the cloth with clean water and wipe away any soap residue.
- Lay the piece flat on a towel and let it dry completely before storing or wearing it again.
Strung pieces need extra patience here. The silk thread running through a knotted strand absorbs moisture, so let it dry fully, ideally overnight, before you put the necklace back on or coil it into a pouch.
What to never use on pearls:
- Ultrasonic or steam cleaners, which AGTA specifically advises against because the vibration and heat can loosen nacre layers or weaken the drill holes.
- Acetone, bleach, or hydrogen peroxide, all of which attack the calcium carbonate structure.
- Abrasive pastes or powders marketed for cleaning silver or gold, since they’re far too rough for a 2.5 hardness surface.
Storing and Traveling With Pearls Without Damage
Pearls need their own space. GIA’s guidance is to store each piece separately in a soft cloth pouch or a lined compartment rather than tossing it into a general jewelry box drawer where it can knock against rings or chains.
A few storage rules worth keeping permanently:
- Use a soft pouch or a fabric-lined box compartment, never a sealed plastic bag for long-term storage, since trapped humidity and lack of airflow can affect the nacre over time.
- Keep pearls away from hot, dry spots like a sunny windowsill or a car glovebox.
- Avoid storing pearls directly against certain woods, since some varieties emit acidic vapors over time, a concern echoed in museum conservation notes on organic materials.
- Separate pearls from harder stones and metal pieces so nothing abrades the surface while sitting in storage.
Pro Tip: If you travel often, dedicate one small soft pouch exclusively to pearls and keep it in your carry-on rather than checked luggage, where temperature swings and rough handling are harder to control.
Wipe pearls down after wearing them on a trip, just as you would at home, before tucking them back into the pouch. The routine doesn’t change because you’re away from your own jewelry box, it just needs to travel with you.
Restringing and When to See a Jeweler
Silk thread stretches, darkens, and wears thin with regular wear, which is why AGTA recommends restringing frequently worn pearl strands roughly every two years, or sooner if you notice the thread looking stretched, dirty, or frayed.
Knots between each pearl aren’t decorative. They keep pearls from grinding against each other as you move, and if the thread ever breaks, knots stop you from losing every pearl off the strand at once, a point GIA also notes in its own care guidance.
Bring a piece to a jeweler for inspection when you notice any of the following:
- Visible stretching or discoloration of the string between pearls.
- A clasp or mounting that feels loose or wiggles more than it used to.
- Dirt or residue visible at the drill holes or under a setting.
- Pearls that look duller than usual even after a gentle cleaning.
Catching these early is far simpler than dealing with a broken strand or a lost pearl later.
Care by Pearl Type: Freshwater, Akoya, Tahitian, and South Sea
Most of the rules above apply across every pearl type, but a few distinctions are worth knowing before you clean or store a specific piece.
- Freshwater pearls: often have thinner nacre in budget pieces, so they benefit from extra gentle handling and a dry cloth over a damp one when possible.
- Akoya pearls: prized for high luster, which shows wear faster than other types, making the post-wear wipe especially worthwhile.
- South Sea and Tahitian pearls: typically have thicker nacre, which adds some durability, but they still need the same chemical avoidance since size doesn’t protect against acids or chlorine.
- Treated, dyed, or coated pearls: require the most caution of all, since AGTA’s treatment guidance notes that dyed color stability varies and some coatings react poorly to even mild soap solutions.
If you’re not sure whether a pearl has been treated, ask the seller before you clean it with anything beyond a dry cloth. A treatment disclosure should tell you exactly which cleaning methods are safe for that specific piece.
Common Pearl Care Mistakes to Avoid
A handful of habits account for most of the pearl damage we hear about, and all of them are easy to skip once you know to watch for them:
- Scrubbing pearls, soaking them for extended periods, or using household cleaners instead of mild soap and water.
- Storing pearls long-term in sealed plastic bags, which traps moisture against the nacre.
- Wearing pearls in a pool or the ocean, since chlorine is specifically called out by GIA as especially damaging, and salt water isn’t safe for regular wear either.
- Attempting DIY “restoration” with harsh chemicals, bleach, or heat to brighten dull pearls, which usually makes the damage permanent.
What Years of Pearl Questions Taught Us About Care
The biggest misconception we run into is that pearls need frequent, intensive cleaning to stay bright. They don’t. A consistent wipe-down after each wear does more for luster than any deep clean, and scheduling a restring every couple of years prevents the kind of damage that no amount of cleaning can fix afterward.
The other lesson is that good buying decisions reduce maintenance later. Asking about treatment disclosure before you buy, and choosing a setting with a secure mount rather than a decorative but flimsy one, means less to worry about once the piece is in regular rotation. We want shoppers to know what they’re getting before a piece ever needs a cleaning routine.

Choosing a well-made piece from the start cuts down on the maintenance this guide covers. A pearl necklace or a pair of pearl studs from our earrings collection is a lovely addition to a jewelry collection.
A few things worth doing before you buy:
- Ask about treatment disclosure on any dyed, bleached, or coated pearls, especially with vintage or estate pieces.
- Look for secure mounts and well-finished clasps, since loose settings create most of the maintenance headaches down the road.
- Browse our full necklaces selection to compare strand lengths, pearl types, and settings side by side.
If you’re building a jewelry collection beyond pearls, our rings and gemstones categories are a good place to keep exploring.
FAQ
How do you clean gold and pearl jewelry together?
Clean the pearl portion with a soft cloth or mild soap and water as described above, and avoid letting any gold-polishing cloth or solution touch the pearls directly. Gold can typically handle a bit more polishing than pearls can, so treat the two materials separately even when they’re mounted on the same piece.
Are cultured pearls worth any money?
Yes, cultured pearls carry real value based on factors like size, shape, luster, surface quality, and nacre thickness, as outlined in GIA’s buying guide. Akoya, South Sea, Tahitian, and freshwater cultured pearls each have their own value range depending on these quality factors.
Can I shower with mother of pearl jewelry?
No, it’s best to remove mother of pearl jewelry before showering or swimming. Soap, shampoo, and chlorine can affect the nacre surface over time, the same way they affect pearls, so GIA’s travel guidance recommends taking these pieces off before any water exposure beyond a quick wipe.
What happens to pearls if they’re not worn?
Pearls kept in storage for long stretches without wear don’t automatically get damaged, but they do need the same care as pearls in rotation: a soft pouch, moderate humidity, and no direct heat. The main risk with long-term storage is sealed plastic or extreme dryness rather than simply not wearing them, so check stored pieces periodically and give them a gentle wipe before putting them away again.
