How to Clean Lab-Grown Diamond Jewellery at Home
Journal • Published July 16, 2026

Skin oils and lotion films quickly build up, making diamonds look cloudy.
Lab-grown diamonds attract skin oils, skincare residue, soap film and dust just as natural diamonds do. That surface build-up can reduce visible brightness without changing the diamond itself.
The safest home-cleaning method depends on the complete jewellery item—not only the diamond. Check the metal, setting, other gemstones, treatments and manufacturer’s instructions before adding water or cleanser.
Quick answer
For modern, undamaged lab-grown diamond jewellery that the seller confirms is compatible with water and mild soap, prepare a small bowl of lukewarm water with a few drops of mild, non-abrasive washing-up liquid. Briefly soak if permitted, clean gently with a new very soft brush—especially behind the diamond—then rinse in a separate bowl, pat dry with a lint-free cloth and inspect again. Stop if a stone moves, the setting is damaged, the piece contains sensitive materials or its treatment history is unknown. Avoid bleach, chlorine, toothpaste, abrasive powders and unapproved ultrasonic or steam cleaning.
First: decide whether home cleaning is appropriate

Never use cleaning routines to verify if setting prongs are loose.
| Condition | Home clean? | Best next step |
|---|---|---|
| Modern diamond-only piece, secure setting, compatible metal | Usually, following seller instructions | Use the gentle routine below |
| Loose, rattling or missing stone | No | Stop wearing; professional inspection |
| Damaged prong, clasp, hinge or thread | No | Repair before cleaning |
| Coloured stones, pearls, enamel, glued elements or coatings | Not without confirmation | Follow material-specific guidance |
| Vintage, antique or unknown construction | Avoid general soaking and brushing | Ask a qualified jeweller |
| Fracture-filled or otherwise treated diamond | Not with a generic routine | Follow laboratory/seller care advice |
What you need
- Two small clean bowls: one for cleaning and one for rinsing.
- Lukewarm water—not hot or boiling.
- A few drops of mild, non-abrasive washing-up liquid confirmed compatible with the piece.
- A new, very soft toothbrush or jewellery brush reserved for cleaning.
- A soft, lint-free cloth.
- A clean towel to cover the work surface.
- Bright, neutral light for inspection.
Avoid working over an open drain. A bowl gives you more control and prevents a loose stone from disappearing into plumbing.
The seven-step home-cleaning method

Brushing pavilion facets removes the skin oils that block light entry.
1. Inspect the dry piece: Audit prongs, check for rattling sounds under neutral light. Stop if loose.
2. Prepare a mild solution: Fill bowl with warm water and mild cleanser. Avoid ammonia or moisturisers.
3. Soak briefly—only if permitted: Follow seller limits. Skip if glued or vintage parts are present.
4. Brush gently, including behind the diamond: Brush pavilions lightly without forcing tips beneath prongs.
5. Rinse in a separate bowl: Rinse in a bowl to prevent drops down plumbing lines. Do not alter water temp quickly.
6. Dry without rubbing the setting: Pat dry with lint-free towels. Avoid hair dryers or hot vents.
7. Inspect again before wearing: Re-check stone alignments before putting the jewelry back on.
Why cleaning behind the diamond matters
Diamonds collect grease quickly. Resides behind pavilions block refraction lines, making clean diamonds look dull. Never use metal pins to clean.
Can you use an ultrasonic cleaner?
Vibrations can shake prongs loose or fracture treated inclusions. For certificate parameters, see what certified lab-grown diamond jewellery means.
Can you steam-clean lab-grown diamonds?
Steam changes thermal levels rapidly, presenting fracture risks. Avoid home steam setups unless approved.
Products and methods to avoid

Abrasives like baking soda and chemicals like bleach scratch gold alloys.
Toothpaste and abrasive powders: Can scratch gold surfaces and clog gallery details.
Chlorine bleach and pool chemicals: Chlorine attacks gold alloy structures. Remove jewelry before swimming.
Baking soda pastes: Abrasive scratch risk for highly polished shanks.
Boiling water: Extreme thermal shock risk for gemstone inclusions.
Alcohol, sanitiser and household sprays: Contains additives that corrode custom finishes.
Sharp tools: Pins scratch metal seats and dislodge claws.
Cleaning different jewellery categories
Lab-grown diamond rings: Remove rings prior to using skin creams or washing dishes.
Lab-grown diamond earrings: Clean posts and backing elements. Wash backings in separate cups.
Lab-grown diamond necklaces and pendants: Support chain links. Ensure bail settings dry completely.
Lab-grown diamond bracelets: Inspect connections. Lay flat on dry towels to prevent link stresses.
Jewellery with coloured stones:
Follow the most sensitive component. See mixed-stone guidelines at how to care for coloured stones and diamonds.
How often should you clean at home?
Clean when film build-ups occur. Routine wiping with lint-free cloths helps limit soap buildup.
When professional cleaning is the better choice
Seek jeweller checks if dirt remains after washing, if mount damage is observed, or if stones show movement.

Final verdict
Frequently Asked Questions
Are lab-grown diamonds cleaned differently from natural diamonds?▼
No because of growth origin alone. Both are diamond; the setting, metal, treatments and other materials determine the safe method.
Can I use washing-up liquid on lab-grown diamond jewellery?▼
A few drops of mild, non-abrasive liquid may suit compatible modern pieces, but follow the manufacturer’s instructions for the exact item.
Can I soak lab-grown diamond jewellery overnight?▼
Do not leave jewellery soaking unattended. Use only the brief period approved for the complete piece.
Can I clean lab-grown diamonds with toothpaste?▼
No. Toothpaste is abrasive and can scratch metal or finishes and lodge in settings.
Can lab-grown diamonds go in an ultrasonic cleaner?▼
Only when a professional has inspected and approved the exact piece. Vibration can affect settings, treatments and other gemstones.
Is steam cleaning safe for lab-grown diamond jewellery?▼
Not universally. Heat and pressure may be unsuitable for other materials, treatments, adhesives or damaged settings.
Why does my lab-grown diamond look cloudy after washing?▼
Soap film, incomplete rinsing, trapped residue or lighting may be responsible. If one gentle re-rinse does not help, seek professional inspection.
How should I clean behind a diamond?▼
Use an approved mild solution and very soft brush with light pressure. Never insert pins or sharp tools into the setting.
Can I clean diamond jewellery over the sink?▼
Use separate bowls over a covered surface. If working near a sink, close the drain securely.
How should I dry diamond jewellery?▼
Pat with a lint-free cloth and allow hidden areas to air-dry completely without external heat.
What if a stone moves during cleaning?▼
Stop immediately, store the piece safely and arrange professional inspection before wearing it again.
Can I use this method on coloured-stone diamond jewellery?▼
Only if every gemstone, treatment, metal and setting is confirmed compatible. Follow the most sensitive component.
