How to Care for Tahitian Pearls: The Dos and Don'ts
To care for Tahitian pearls, wipe them with a soft damp cloth after every wear, keep them away from perfume, hairspray and household chemicals, store them flat in a soft pouch apart from hard jewellery, and have knotted strands restrung every couple of years. Pearls are organic, so they want gentleness and a little humidity, never harsh cleaners.
People expect pearl care to be fussy. It isn't. A Tahitian is far tougher than its reputation suggests — it has survived years in a salty lagoon, after all — but it does ask for a few habits that a diamond would shrug off. Follow the simple rhythm below and a strand will easily outlive you.
The dos and don'ts at a glance
Pearls are the last thing you put on and the first thing you take off. Build the rest of your care around that single rule.
| Do | Don't |
|---|---|
| Wipe with a soft damp cloth after wearing | Use ultrasonic cleaners, steam or vinegar |
| Put pearls on last, after perfume and makeup | Spray hairspray or scent while wearing them |
| Store flat in a fabric pouch or lined box | Toss them in a box with rings and hard stones |
| Wear them often so skin oils keep nacre supple | Lock them away airtight for years |
| Restring knotted strands every 2–3 years | Swim, shower or sleep in them |
Why pearls need different rules
A Tahitian pearl is nacre — layered aragonite and conchiolin grown by the oyster Pinctada margaritifera. That makes it softer and more porous than a diamond or a sapphire, sitting around 2.5 to 4.5 on the Mohs hardness scale. Acids dull it, heat dries the nacre, and grit scratches the surface. The dark body colour is grown by the oyster and is never dyed, so there's no coating to protect; you're simply looking after a living material.
Cleaning, step by step
- Lay the strand flat on a soft, clean towel.
- Dampen a microfibre cloth with lukewarm water, adding the tiniest drop of mild soap only if a pearl is visibly marked.
- Wipe each pearl, then go over it again with a second clean damp cloth to lift any residue.
- Lay the strand flat to dry fully before putting it away — never hang a wet knotted strand, because the damp silk stretches and the knots loosen.
Storing them so they last
Keep pearls somewhere with a little air and humidity. A bone-dry safe or a sealed plastic bag can make nacre brittle over decades, while a breathable pouch inside a drawer is close to ideal. Always keep them away from metal clasps and faceted stones in the same compartment, since those edges are what cause most of the fine scratches we see come back across the bench.
When to restring
If you wear a knotted strand weekly, plan to restring every two to three years on fresh silk. The knots between each pearl do two jobs: they stop the pearls rubbing each other, and they keep the whole strand from spilling if the thread ever fails. Grey, fuzzy or stretched silk between pearls is your cue that it's time.
Can I shower in my Tahitian pearls?
No. Soap film, shampoo and hot water dull the lustre over time and weaken knotted silk. Take them off first — it only takes a moment, and your pearls will thank you for it for years.
My pearls touched perfume. Now what?
Wipe them straight away with a soft damp cloth before the scent dries onto the nacre. Caught early it does no harm; left to sit, perfume and the alcohol in it slowly etch the surface.
How often should I actually clean them?
A quick wipe after each wear is enough for everyday care. A gentle damp clean every month or two handles built-up skin oils. Anything more aggressive than that does more harm than good.
