Diamonds Are Durable—But Not Indestructible

One of the most appealing qualities of a diamond is its reputation for hardness: it is the hardest known material on earth, rated 10 on the Mohs hardness scale. This makes it extremely resistant to scratching. But hardness is not the same as indestructability, and a lab-grown diamond engagement ring still requires some care to keep it looking its best for a lifetime of wear.

Daily Care: Protecting Your Ring at Home

Remove Your Ring During Messy Tasks

Remove your ring before cooking, cleaning, gardening, or any activity where the ring might be exposed to harsh chemicals, grit, or physical impact. A diamond can withstand a lot, but it can chip if hit at the right angle against a hard surface. The metal setting is more vulnerable than the diamond itself.

Be Careful with Chemicals

Diamonds are resistant to acids and most chemicals, but the metals in your setting are not. Chlorine bleach, harsh cleaning products, and even some hairsprays and perfumes can damage or discolor gold, platinum, and other metals over time. Put your ring on last when getting dressed (after applying perfumes, lotions, and hairspray) and remove it first when undressing.

The Lotion Problem

The single biggest threat to your ring's appearance in daily life is probably skincare products. Sunscreen, moisturizer, body lotion, and similar products create a film on the diamond that dulls its brilliance. This is not damage—it is just buildup that needs to be cleaned. But if left for weeks, it can accumulate into a layer that requires professional cleaning to remove. Make it a habit to remove your ring before applying skincare products.

Weekly Cleaning: At-Home Care

Cleaning your ring at home is simple and takes less than five minutes. Here is the recommended method:

The Gentle Soak Method

1. Fill a small bowl with warm (not hot) water and a drop of mild dish soap.
2. Place your ring in the bowl and let it soak for 15-30 minutes.
3. Use a soft-bristled toothbrush (a baby toothbrush works well) to gently scrub around the diamond and setting, paying special attention to the underside of the stone where buildup accumulates.
4. Rinse thoroughly with clean water.
5. Dry with a lint-free cloth or a soft jewelry cloth.

What Not to Use

• Abrasive cleaners: Baking soda, toothpaste, or any scrub that is not specifically designed for jewelry will scratch metals over time.
• Steam cleaners designed for home use: Unless specifically designed for jewelry, they can damage certain settings or cause thermal shock to the stone.
• Bleach or chlorine: These can damage gold and platinum settings.

The Ultrasonic Cleaner Question

Ultrasonic cleaners use high-frequency sound waves to震动 loose debris from jewelry. They are effective for cleaning heavily soiled rings, but they carry some risk: the vibrations can loosen stones in their settings, particularly if the ring already has weakened prongs or a loose stone. Use an ultrasonic cleaner no more than once a month, and always have your ring checked for loose stones afterward. For regular weekly cleaning, the soak and brush method is safer.

Annual Maintenance: Professional Care

Professional Cleaning and Inspection

Take your ring to a professional jeweler once a year for a thorough cleaning and inspection. A professional cleaning will remove buildup that at-home cleaning cannot, and a trained eye can identify potential problems before they cause loss of a stone: worn prongs, a thinning shank, a loose stone, or a damaged setting. Many jewelers offer free cleaning and inspection.

Rhodium Plating Maintenance

If your ring is set in white gold, it was plated with rhodium to give it a bright white finish. This plating wears off over time, revealing the slightly warmer tone of the underlying gold. Most white gold rings need to be re-plated every 2-3 years depending on wear. Re-plating is affordable and restores the ring to a like-new appearance. Watch for the appearance of a yellowish tone as the sign that re-plating is needed.

Polishing

Daily wear causes microscopic scratches in the surface of gold and platinum, making the ring lose its original high polish over time. Professional polishing restores the mirror finish and removes surface scratches. It removes a tiny amount of metal each time, so do not polish too frequently—once a year is sufficient for most rings.

When to Remove Your Ring

There are specific situations where removing your ring is strongly recommended:

• Swimming: Chlorinated water and cold fingers (which cause fingers to shrink) create a real risk of the ring slipping off in a pool. Remove before swimming.
• At the gym: Physical activity increases the risk of physical impact to the ring and exposes it to sweat and salt.
• Sleeping: Most jewelers recommend removing your ring before sleeping. The ring can snag on bedding, and prongs can be stressed by pressure over hours.
• Applying products: Skincare, sunscreen, cleaning products, and hair products all create buildup on the diamond.
• Cooking: Food prep exposes the ring to oils, spices, and physical contact with cutting boards and utensils.

Storage: When You Are Not Wearing It

When you are not wearing your ring, store it in a jewelry box or soft pouch. Keep it separate from other jewelry to prevent scratching—diamonds can scratch other diamonds and softer gemstones. A ring box with individual compartments is ideal.

If you travel, bring a dedicated jewelry case. Check that the case is secure and cannot open accidentally in your luggage.

What to Do If Your Ring Is Damaged

If you notice a loose stone, a bent or lifted prong, a crack in the shank, or any other damage, stop wearing the ring and take it to a jeweler immediately. Wearing a damaged ring risks losing the stone. Most jewelers can repair a damaged ring within a few days to a week, depending on the type of damage.

Insurance and Documentation

Keep your original purchase receipt, the GIA or IGI certificate, and any appraisal documentation in a safe place outside of your jewelry box. These documents are essential for insurance claims and future resizing or repair work. Consider storing digital copies in a cloud service as a backup.
