Diamonds attract grease. Hand cream, skin oils and soap residue collect on the stone, especially on the pavilion underneath, and block the light that makes a diamond sparkle. A clean ring can look transformed.
A five-minute routine
- Soak the ring for a few minutes in warm water with a few drops of mild washing-up liquid.
- Brush gently with a very soft toothbrush, reaching under the stone and between the prongs.
- Rinse in a bowl of clean water, never over an open drain.
- Dry with a lint-free cloth and avoid touching the stone with your fingers afterwards.
What to avoid
- Chlorine and harsh household cleaners, which can damage the metal.
- Abrasive powders and toothpaste, which scratch metal.
- Ultrasonic or steam cleaning at home if the diamond has been fracture-filled, if other gems in the ring are sensitive, or if the setting may be loose.
While you clean, check
- Does the stone move when you touch it gently?
- Do any prongs catch on a cloth?
- Are any small stones missing from a halo or pavé band?
If so, stop wearing the ring and have it checked by a jeweller.
Why diamonds get dirty so quickly
Diamond's surface attracts oil and grease. Even a thin film of hand cream on the pavilion, the underside of the stone, stops light from reflecting back through the top, and the diamond looks dull. That is why a ring can lose its sparkle within days and regain it in minutes.
Halo and pavé rings
Rings with many small stones collect dirt in the spaces between settings. Brush gently in several directions and rinse well. Take care not to catch the brush bristles on the tiny beads of metal holding the stones, and check afterwards that none are missing.
Cleaning while travelling
A soft brush, a small bottle of mild soap and a lint-free cloth are enough. Clean the ring in a bowl or a closed basin, never over an open drain, and let it dry fully before storing it.
Myths to avoid
- Toothpaste: abrasive, and it scratches metal.
- Vinegar or lemon: acidic, not good for metals or other stones.
- Boiling: a sudden temperature change can harm other stones and some treatments.
- Bleach: can damage gold alloys.
Professional cleaning
A jeweller can use steam or ultrasonic cleaning when appropriate and, more importantly, inspect the setting under magnification. For a ring worn every day, once or twice a year is sensible.

Frequently asked questions
Why does my diamond look cloudy?
Usually because oils, lotion and soap have built up on the stone, especially underneath. Cleaning restores its brilliance.
How often should I clean my ring?
A quick clean once a week keeps it bright; a professional clean and check once or twice a year is ideal.
Can I use a toothbrush on my diamond ring?
Yes, a very soft one, gently, with warm soapy water.
Will cleaning damage my ring?
Gentle cleaning with mild soap is safe for diamonds and precious metals. Avoid abrasives, bleach and ultrasonic cleaning for treated stones.
