How to Clean a Diamond Necklace (and Keep It Bright)
How to Clean a
Diamond Necklace
A diamond necklace dims from a film of everyday life, not from age. Here's the gentle way to bring it back — and the habits that keep the chain and clasp sound.
The gentle
home clean
Diamonds go dull because oils and lotion collect behind the stones. A soft wash restores them:
- Fill a small bowl with warm (not hot) water and one drop of mild dish soap.
- Soak the necklace a few minutes to loosen the film.
- Brush gently behind and around the diamonds with a soft toothbrush.
- Rinse in clean water over a mesh strainer — never an open drain.
- Pat dry with a lint-free cloth and let it air-dry fully before storing.
Don't swim or
shower in it
It's tempting to leave a favourite necklace on, but a diamond piece is happiest when it comes off for water and sweat. Pool chlorine and salt water can pit and weaken gold over time; soap and shampoo leave the film that dulls the diamonds; and exercise adds knocks and snags that stress a fine chain and clasp.
Make it the last thing on and the first thing off, and it stays brighter and more secure for years.
Check the clasp
and chain
Cleaning is the moment to inspect. Work along the chain for kinks or thin spots, and open and close the clasp to feel that it still springs shut firmly. On a diamond bar or pendant, gently check nothing feels loose in the setting.
A clasp that no longer clicks securely is the most common way a necklace gets lost - fix it before wearing it out.
Keep the chain
tangle-free
A fine chain's worst enemy is a knot, and knots happen in storage. Fasten the clasp before you put it away, and lay it flat or hang it at full length rather than dropping it in with other pieces.
For travel, thread it through a small pouch or a soft roll so it can't wind around itself.
How to
store it
Give a diamond necklace its own soft pouch or a lined slot, away from harder pieces - diamonds are hard enough to scratch almost everything else in the box. Keep it dry and separate, and a delicate chain will stay kink-free.
When to see a
jeweler
Book a professional clean and check once or twice a year if you wear the necklace often, or sooner if the clasp feels loose, a stone seems to move, or the sparkle doesn't return after washing. A quick setting and clasp check is inexpensive insurance for a piece you plan to keep.

Frequently asked
How do you clean a diamond necklace at home?
Soak it briefly in warm water with a drop of mild dish soap, then brush gently behind and around the diamonds with a soft toothbrush to lift skincare and oils. Rinse in clean water over a strainer and pat dry with a lint-free cloth.
Can you swim or shower with a diamond necklace?
It is better not to. Pool chlorine and salt water can damage gold over time, soap and shampoo leave a film that dulls the diamonds, and knocks or snags can stress the clasp and chain. Take a diamond necklace off for swimming, showering and workouts.
How do you keep a thin gold chain from tangling?
Fasten the clasp before you put it away and store it flat or hung at full length, rather than dropped into a dish with other pieces. For travel, thread the chain through a small pouch or a soft roll so it stays straight.
How often should you clean a diamond necklace?
A gentle wipe after wear and a soapy-water clean every couple of weeks keeps most everyday diamond necklaces bright. Have it professionally checked and cleaned once or twice a year, especially if you wear it often.
