Diamond Jewelry Care Guide: How to Keep Your Diamonds Brilliant

Diamonds Are Durable — But Not Indestructible

Diamond is the hardest natural substance on earth (10 on the Mohs scale), but hardness and toughness are different things. A diamond can chip or crack if struck sharply at the right angle, and it attracts grease and oils like a magnet — which is why even the most brilliant stone can look dull after regular wear without proper care.

Whether you're wearing a 14K Yellow Gold Diamond Cross Pendant, a 14K Yellow Gold Diamond Hamsa Pendant, or pieces from our Diamond Crosses collection, these care practices will keep your jewelry looking exactly as it should.

Daily Wear: What to Avoid

The biggest enemies of diamond jewelry aren't physical damage — they're everyday substances that accumulate invisibly:

  • Hand lotion and skincare products: Oils and emollients coat the pavilion of the diamond (the underside), killing brilliance from beneath. Apply lotion before putting on jewelry, never after.
  • Chlorine (pools, hot tubs, cleaning products): Chlorine chemically attacks gold alloys, especially 14K and 10K, weakening prongs over time. Always remove diamond jewelry before swimming.
  • Perfume and hairspray: Alcohol-based sprays leave a film on diamonds and can dull the surface of the metal setting. Spray first, let dry, then put on your jewelry.
  • Cooking oils and grease: Kitchen work and diamond rings are not a good combination. Remove rings before cooking.

How to Clean Diamond Jewelry at Home

The most effective at-home cleaning method is also the simplest:

  1. Fill a small bowl with warm (not hot) water and a few drops of mild dish soap — nothing abrasive or bleach-based.
  2. Place your jewelry in the solution and let it soak for 20–30 minutes to loosen buildup.
  3. Use a soft-bristle toothbrush (a baby toothbrush works perfectly) to gently scrub around the setting, under the diamond, and along the metal surface.
  4. Rinse thoroughly under warm running water. Use a drain stop — don't risk losing a pendant down the drain.
  5. Pat dry with a lint-free cloth and allow to air-dry completely before storing.

What not to use: Ultrasonic cleaners can loosen prong settings, especially on older pieces or rings with fracture-filled diamonds. Toothpaste is abrasive and will scratch both metal and stone surfaces. Boiling water can crack diamonds with pre-existing inclusions.

Storage: Protecting Diamonds from Each Other

This is where most people make mistakes. Diamonds scratch other gemstones — and they can scratch each other if stored in contact. Store each piece individually in:

  • Soft fabric pouches (the pouches most fine jewelry comes with are perfect)
  • Separate compartments in a lined jewelry box
  • Individual zip-lock bags as a budget-friendly alternative

Never pile diamond jewelry in a single drawer or dish. Chains, pendants, and rings stored together tangle and rub — the chain metal scratches, and any two diamonds in contact can damage each other's girdles (the thin edge of the stone).

When to Get Professional Inspection

Even with careful daily wear, diamond settings loosen over time. Prongs bend slightly, microscopically, with every contact. A loose prong is how diamonds get lost — not through impact, but through the slow fatigue of regular wear.

Best practice:

  • Every 12 months: Have a jeweler check all prongs for tightness and inspect the setting for wear
  • Every 18–24 months: Professional ultrasonic cleaning and full inspection, including checking for any new chips or inclusions that have grown
  • Immediately if a stone looks loose, rocks slightly in the setting, or if you hear it rattle

Special Considerations by Jewelry Type

Diamond pendants and crosses: Pay attention to the bail (the loop connecting the pendant to the chain). Bails can wear thin with daily chain movement. Check that the bail is fully closed and hasn't thinned to the point of potential breakage. Our 14K Diamond Cross Pendant and 14K White Gold 1.00 CTW Diamond Cross Pendant are set in durable 14K gold — ideal for everyday pendants.

Diamond rings: Rings take the most daily abuse of any jewelry type. Avoid wearing rings during weightlifting, rock climbing, or any activity involving bars or handrails — sharp impacts can chip a diamond's girdle or bend a prong significantly in one strike.

Diamond earrings: Hair products and behind-the-ear skincare buildup are the main concerns. Clean earring backs regularly and check that butterfly backs are secure.

Insurance and Documentation

Fine diamond jewelry should be insured. For any piece above $500 in value, a jewelry floater on your homeowner's or renter's policy covers loss, theft, and accidental damage — typically for 1–2% of the appraised value per year. Keep photographs of your pieces and any purchase receipts or appraisals on file.
