Fine jewellery is made to be worn, and a little regular care keeps it looking its best for generations. The reassuring truth is that most everyday cleaning can be done safely at home in a few minutes, with nothing more than warm water, a drop of mild soap and a gentle touch. What matters is knowing which methods are safe, which stones need special handling, and when a piece is better left to a professional. This guide covers cleaning, storage and the small daily habits that protect everything from a diamond solitaire to a strand of pearls between visits to the workshop.
In short: clean most diamond and hard-stone jewellery in warm water with a little mild washing-up soap and a soft brush, then rinse and pat dry. Never soak emeralds, opals or pearls, store every piece apart so harder stones cannot scratch softer ones, and have your settings inspected once or twice a year. Treat the metal and the gemstone according to their own natures and a fine piece will last a lifetime.
Safe At-Home Cleaning
For most diamond and hard coloured-stone jewellery, the safest method is also the simplest. You do not need specialist products or machines; you need warm water, a mild soap, a soft brush and a few quiet minutes.
The warm-water method
Half-fill a small bowl with warm, not hot, water and add a little mild washing-up soap. Soak the piece for a few minutes to loosen the skin oils and everyday grime that dull sparkle, then clean gently behind and around the stones with a soft-bristled brush such as a baby toothbrush, paying attention to the underside of the setting where light enters a diamond. Rinse in clean warm water over a closed drain or a sieve so nothing is lost, and dry with a soft, lint-free cloth. A dedicated polishing cloth then restores shine to gold and platinum between cleans.
How often to clean
A quick clean every week or two keeps diamonds, sapphires and rubies bright, and rings worn daily benefit most because hand cream and soap build up fastest in the setting. Necklaces and earrings worn less often need attention only when they look dull. The aim is little and often: a gentle clean before grime has a chance to harden is far kinder to a piece than an occasional vigorous scrub.
A Care Routine by Metal
The metal a piece is made from decides part of its care. Our guide to precious metals explains the differences in full, but the cleaning rules are simple.
Platinum and yellow gold
Platinum and yellow gold hold their colour permanently and ask very little of you. Warm soapy water and a soft cloth keep them bright, and platinum in particular develops a soft satiny sheen known as a patina over years of wear, which many owners prize and which a quick professional polish removes whenever you prefer a high shine. Rose gold is equally low-maintenance and keeps its warm tone for life.
White gold and rhodium plating
White gold is finished with a thin layer of rhodium for its bright, cool-white shine. That plating wears gradually with daily use and can begin to show a faint warm tint underneath, especially on a ring. A simple workshop replating, part of our aftercare service, returns it to its whitest. Clean white gold gently and avoid abrasives, which thin the plating faster.
Caring for Coloured Gemstones
Hardness and structure vary enormously across the gem world, so a method that is perfect for a diamond can ruin a softer stone. Hardness is measured on the Mohs scale from one to ten, and it is the single best guide to how robust a stone is. The table below summarises safe care for the gems we set most often.
| Gemstone | Mohs hardness | Warm soapy water | Ultrasonic cleaner | Key note |
|---|---|---|---|---|
| Diamond | 10 | Yes | Usually safe | The hardest gem, yet a sharp knock can still chip a facet edge |
| Ruby and sapphire | 9 | Yes | Usually safe | Very durable corundum, ideal for everyday wear |
| Emerald | 7.5 to 8 | Quick wipe only | Never | Commonly oil-treated, so never soak, steam or ultrasonic |
| Aquamarine and topaz | 8 | Yes | With caution | Hard but can chip or cleave on a hard blow |
| Tanzanite | 6 to 7 | Brief and gentle | Never | Sensitive to heat, sudden temperature change and impact |
| Opal | 5.5 to 6.5 | Damp wipe only | Never | Porous and water-bearing, can craze if soaked or dried out |
| Pearl | 2.5 to 4.5 | Damp wipe only | Never | Organic and porous, wipe after wear and restring on silk |
Hard, durable stones
Diamonds, rubies and sapphires sit at the top of the scale and tolerate the warm-water method happily, which is why they suit daily wear so well. Even so, hardness is not the same as toughness: a diamond is the hardest natural material yet can still chip on a sharp impact against a worktop or door frame, so take rings off for heavy or rough tasks. Topaz and aquamarine are hard but have cleavage planes, so treat them with the same respect.
Soft, porous and organic gems
Emeralds, opals, pearls, turquoise and tanzanite need the gentlest hand. Emeralds are almost always oiled to fill natural fissures, and soaking, steam or an ultrasonic cleaner will strip that oil and leave the fissures visible, so clean them with no more than a damp cloth. Opals are porous and contain water, so they can craze if soaked or allowed to dry out. Pearls are organic and easily scratched; treat them as described below. When in doubt, a damp wipe is always safe, and our coloured gemstone collection team is glad to advise on a specific piece.
The Golden Rules: Do's and Don'ts
Most damage to fine jewellery comes not from age but from a handful of avoidable habits. Keep these in mind and your pieces will need far less remedial work over the years.
| Do | Don't |
|---|---|
| Use warm water and a little mild washing-up soap | Use toothpaste, bleach or scouring powder |
| Clean gently with a soft baby toothbrush | Scrub with anything stiff or abrasive |
| Remove rings for sport, gardening and cleaning | Wear fine pieces in swimming pools or hot tubs |
| Apply perfume and lotion before putting jewellery on | Spray scent or hairspray over your jewellery |
| Store pieces separately in a lined box or pouch | Pile rings and chains together in one drawer |
| Have prongs and clasps checked once or twice a year | Ignore a stone that rattles or a worn claw |
Storage, Removal and Routine Checks
How you store and handle a piece between wears matters as much as how you clean it. A few simple routines prevent the scratches, tangles and lost stones that account for most workshop repairs.
Storing your pieces
Store each piece separately so that harder stones cannot scratch softer ones, using a lined box with individual compartments or soft pouches. Chains are happiest fastened and laid flat to prevent tangling and kinks, and pearls prefer a breathable pouch rather than an airtight box, since they benefit from a little ambient moisture. Keep boxes out of direct sunlight and away from radiators, as prolonged heat and dryness are unkind to softer and organic gems.
A one-minute monthly check
Once a month, give your pieces a quick check at a well-lit table. Look closely at the prongs holding each stone, gently feel for any movement or rattle, test the clasps on necklaces and bracelets, and run a fingertip or a piece of soft fabric around each setting; a tiny snag often reveals a lifted claw before it becomes a lost stone. Build the habit of taking jewellery off before showering, swimming, sleeping in pieces that can snag, and any rough work, and always put rings on last, after cosmetics have dried.
Caring for Pearls and Other Organics
Pearls and other organic gems deserve a paragraph of their own because their care is so particular. A pearl should be the last thing you put on and the first you take off, kept away from perfume, hairspray and acids that etch its surface. After wearing, simply wipe each pearl with a soft, slightly damp cloth; never soak a strand. Have pearl necklaces restrung periodically, ideally on knotted silk so that a broken thread never scatters the pearls and so the pearls do not rub against one another. Coral and amber, also organic, ask for the same gentle, scent-free handling. Our pearl buying guide covers types and quality in more detail.
When to Bring It to Us
Even with attentive home care, fine jewellery deserves a professional clean and inspection once or twice a year. Under magnification a jeweller can check settings, tighten prongs, service clasps, replate white gold and refresh the original finish, catching small problems long before they cost you a stone. At our boutique in George Town, Grand Cayman, our GIA-certified team offers exactly this aftercare; visit us whenever it suits you with no appointment needed. Every piece you buy carries lifetime care, every purchase is tax-free with no sales tax and no VAT, and we are always happy to talk through caring for a treasured heirloom.
