How to Clean Lab-Grown Diamond Jewelry at Home
Lab-grown diamonds have the same fundamental diamond properties as natural diamonds, so they can be cared for in much the same way. Regular cleaning helps remove oil, dust, lotion, and everyday buildup that can reduce a diamond's sparkle.
The good news is that you don't need expensive equipment to clean most lab-grown diamond jewelry at home.
What You Need
- Warm water
- Mild soap
- Small bowl
- Soft toothbrush
- Clean microfiber or lint-free cloth
Avoid abrasive cleaners, toothpaste, bleach, and chlorine-based products. These can damage jewelry metals and finishes.
Step-by-Step: How to Clean Lab-Grown Diamond Jewelry
1. Prepare Warm Soapy Water
Fill a small bowl with comfortably warm water and add a few drops of mild soap.
IGI recommends using warm water and a neutral-pH detergent for home jewelry cleaning.
2. Soak the Jewelry
Place your jewelry in the solution for a few minutes.
This helps loosen oils, dirt, and residue around the diamond and setting.
3. Gently Brush the Jewelry
Use a soft or extra-soft toothbrush to gently clean:
- Around the diamond
- Under the stone
- Behind the setting
- Around the prongs
- Inside the ring
The underside of a diamond can collect significant oil and dirt, so don't overlook this area.
4. Rinse Carefully
Rinse the jewelry with clean, warm water.
If using a sink, close the drain first or rinse the piece in a bowl to avoid accidentally losing it.
5. Dry With a Soft Cloth
Gently pat the jewelry dry with a clean microfiber or lint-free cloth.
Avoid abrasive paper products that could scratch softer jewelry metals.
How Often Should You Clean Lab-Grown Diamond Jewelry?
For frequently worn pieces, a gentle home cleaning once or twice a week can help remove everyday buildup. A quick wipe with a soft cloth after wearing can also reduce the accumulation of sweat, oils, and cosmetics.
Professional cleaning and inspection should also be considered periodically, particularly for engagement rings and frequently worn pieces.
What Not to Use on Lab-Grown Diamond Jewelry
Avoid:
- ❌ Toothpaste
- ❌ Abrasive powders
- ❌ Bleach
- ❌ Chlorine
- ❌ Harsh household cleaners
- ❌ Hard-bristle brushes
- ❌ Unapproved chemical solutions
GIA specifically warns against abrasive household cleansers and chlorine-based products for diamond jewelry because they can damage metals and settings.
Can You Use an Ultrasonic Cleaner?
Be careful.
Although diamonds themselves are highly durable, ultrasonic vibration can potentially loosen stones in a setting that is already damaged or insecure. GIA recommends that ultrasonic cleaning be handled cautiously, particularly when jewelry contains vulnerable stones or settings.
For valuable or intricate jewelry, professional cleaning is the safer option.
How to Keep Lab-Grown Diamond Jewelry Sparkling
Cleaning is only part of good jewelry care.
Remove Jewelry Before:
- Showering
- Swimming
- Exercising
- Cleaning with chemicals
- Applying lotions or heavy cosmetics
Store Jewelry Separately
Keep each piece in its own soft pouch or compartment to reduce scratching and contact with other jewelry. IGI recommends separate storage to prevent pieces from scratching one another.
Check the Setting Regularly
Look closely at the prongs and setting.
If a diamond appears loose or the prongs look damaged, stop wearing the piece and have it checked by a professional jeweler.
Quick Cleaning Routine
Warm water → Mild soap → Soft brush → Gentle rinse → Microfiber cloth
That's all you need for routine cleaning of most lab-grown diamond jewelry.
Frequently Asked Questions
Can I clean lab-grown diamonds with soap?
Yes. Warm water and mild soap are a simple home-cleaning method recommended for diamond jewelry.
Can I use a toothbrush to clean a lab-grown diamond?
