Most fine jewelry doesn't need much. A soft cloth, the right storage, occasional cleaning, and a watchful eye for loose stones. The trouble is that most of what people do at home — assuming it's helping — is actually shortening the life of their pieces.
I'm a GIA Graduate Gemologist and I see jewelry come back for repair every week that was damaged by well-intentioned care. This is the guide I wish every client read before they bought their first piece.
What to do every day
Almost nothing. Wear your jewelry. Take it off before showering, swimming, sleeping, and exercising. Wipe it with a soft cloth when you put it away. That's the daily routine.
- Take it off before applying lotion, perfume, or sunscreen — these dull stones and tarnish metal over time.
- Take it off before swimming. Chlorine and saltwater both damage gold over years of exposure.
- Take it off before sleeping. Chains tangle, settings catch, and pieces wear down faster than they should.
- Wipe pieces with a soft cotton or microfiber cloth before storing them. This removes oils and prevents buildup.
What to do once a month
A gentle cleaning at home, by hand, in warm water with a tiny drop of mild dish soap. Soak for a few minutes, brush gently with a soft baby toothbrush, rinse, dry with a soft cloth. That's it.
This works for most diamond and gold pieces. Do not use this method on the exceptions listed below.
What never to do
These are the four things I see ruin pieces most often.
- Never use an ultrasonic cleaner on guilloché enamel. The vibrations can crack the enamel beyond repair. This is non-negotiable. If you own any guilloché piece, ultrasonics are off the table forever.
- Never use an ultrasonic cleaner on emeralds, opals, pearls, turquoise, or any organic or treated stone. Same reason — vibration damages the stone or strips treatment.
- Never clean jewelry with toothpaste. The internet recommends this constantly. It's an abrasive and it scratches gold and softer stones. Stop.
- Never store pieces touching each other. Diamonds scratch every other gemstone. Hard stones scratch softer stones. Always store pieces separately, in soft pouches or a divided jewelry box.

How to clean specific stones and materials
Some pieces need a different approach.
- Diamonds and sapphires (Mohs 9 and 10): warm water with mild soap, soft brush. Safe for occasional ultrasonic cleaning if you don't have other materials in the piece.
- Emeralds (often oiled): soap and warm water only. No ultrasonic, no steam. The oil treatment can be stripped, leaving the stone duller and more visible inclusions.
- Pearls: damp cloth only. Never submerge pearls in water — it can break down the silk thread used in stringing and damage the nacre. Restring strands every 2 to 3 years if worn frequently.
- Opals: damp cloth only. Opals contain water and can crack if dried out or shocked with temperature changes. Store away from heat sources.
- Guilloché enamel: dry soft cloth only. Avoid water, avoid heat, avoid vibration. Store separately.
- Essex crystal: dry soft cloth only on the front. Avoid getting moisture behind the setting where the painted surface is.
How to store fine jewelry
The single best thing you can do for the lifespan of your jewelry is store it properly. Most damage I see isn't from wear — it's from pieces banging against each other in a single drawer or pouch.
Store every piece in its own compartment, ideally lined with a soft fabric. A divided jewelry box is the right tool. A travel jewelry box matters too — pieces that travel with you in a single zippered pouch will rub and scratch, especially in checked or thrown bags.
Keep humidity moderate. Too dry and pearls and opals can crack; too humid and silver tarnishes faster. A small silica packet in your jewelry box absorbs excess moisture.
When to bring it to a jeweler
Once a year, every fine piece should be inspected by a jeweler. This isn't a hard sell — it's the equivalent of a dental cleaning. They check for loose stones, worn prongs, thinning bands, and weakening clasps. A loose stone caught in time costs $50 to retighten. The same stone after it falls out costs whatever the stone costs to replace.
If you bought a piece from L'Heritage, annual inspection is included. Just send me a note and we'll arrange it.
Take care of your pieces and they'll outlast you. That's the whole point of fine jewelry.
