You invested in a beautiful nacre (mother of pearl) brooch or bracelet. You wear it often. And now you're wondering: how do I keep it looking its best?
Every month, 170 people search "how to clean mother of pearl" — and most of them find incomplete or contradictory advice. So we created this definitive guide based on our experience as nacre jewelry makers.

Understanding Nacre: Why Care Matters
Nacre is an organic material — calcium carbonate layers secreted by mollusks. This is what gives it iridescence (the microscopic layers refract light differently at each angle), but it also means nacre is:
- Porous — it can absorb oils and chemicals
- Soft — 2.5-4.5 on the Mohs scale (softer than most gemstones)
- Temperature-sensitive — extreme heat can cause cracking
- Water-sensitive — prolonged exposure weakens the structure
But with proper care, nacre jewelry lasts generations. That's why antique nacre pieces from the Ming Dynasty still shimmer in museums today.

Daily Care (30 Seconds)
After each wear, simply:
1. Wipe with a soft, dry cloth — microfiber or flannel works best
2. Check the pin back — make sure it's secure and not bent
3. Remove before: swimming, showering, applying perfume, using cleaning products
That's it. Thirty seconds that add years to your piece's life.

Weekly Cleaning (2 Minutes)
If you wear your nacre jewelry daily, give it a gentle clean once a week:
1. Dampen a soft cloth with lukewarm water (not hot!)
2. Wipe the nacre surface gently — no rubbing, no pressure
3. Dry immediately with a separate soft cloth
4. Let air-dry completely before storing (5 minutes)
⚠️ Never submerge your nacre jewelry in water. Never soak it. Never put it under running water.

Monthly Deep Clean (5 Minutes)
Once a month, give your nacre pieces extra attention:
1. Mix one drop of mild soap (baby soap or dish soap, nothing with moisturizers) in a small bowl of lukewarm water
2. Dip a soft cloth in the solution and wring it out until barely damp
3. Gently wipe the nacre surface
4. Rinse the cloth in clean water, wring out, and wipe again to remove soap residue
5. Dry thoroughly with a soft cloth
6. Let air-dry for 10 minutes before storing

What NEVER to Do with Nacre
| ❌ Never | Why | What to Do Instead |
| ❌ Never | Why | What to Do Instead |
|---|---|---|
| Ultrasonic cleaner | Vibrations crack the layered structure | Gentle hand wipe only |
| Chemical jewelry cleaner | Acids dissolve calcium carbonate | Mild soap + water, barely damp |
| Steam cleaning | Heat shock causes cracking | Room temperature only |
| Bleach or ammonia | Destroys the organic protein layers | No chemicals, ever |
| Toothbrush | Bristles scratch the surface | Soft cloth only |
| Prolonged sunlight | UV fades colors over time | Store in dark place |
| Hot water | Causes thermal shock | Lukewarm or room temperature only |
| Perfume/hairspray directly on it | Chemicals eat into the surface | Apply products first, then put on jewelry |

Storage Best Practices
1. Individual soft pouches — each piece in its own pouch to prevent scratching
2. Separate from harder jewelry — don't store nacre next to metal or gemstone pieces
3. Cool, dry place — avoid bathrooms (humidity) and windowsills (sunlight)
4. Use the original box — our gift boxes are designed for long-term storage
5. Add a silica gel packet — if you live in a humid climate, a small desiccant packet prevents moisture damage

How Nacre Ages (And Why That's Beautiful)
Unlike synthetic materials that yellow, crack, or fade, well-cared-for nacre develops a warm patina over time. The iridescence may soften slightly, but it gains depth and character.
Many collectors actually prefer the aged look — it's the difference between a new violin and a Stradivarius. The patina tells a story of years of being worn and loved.
If you prefer to maintain the original brightness:
- Store away from light when not wearing
- Clean regularly with the weekly method above
- Avoid oils (remove before cooking, applying lotion)

Troubleshooting Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Cloudy appearance | Oil buildup from skin | Gentle weekly clean with mild soap |
| Small scratches | Stored next to harder jewelry | Can be professionally polished; prevent with proper storage |
| Dull area | Chemical exposure | Unfortunately irreversible; prevent by removing before products |
| Loose metal setting | Wear and tear | Contact us for repair advice |
| Dark spots | Moisture damage | Dry thoroughly after each wear to prevent progression |
