How to clean a diamond ring at home

A diamond is designed to catch light, and a film of hand cream, soap or everyday oils dulls it faster than most people expect. The good news: for the great majority of rings, a proper clean takes a few minutes at home with things you already own.

The simple method that works for most rings

Warm water and a little washing-up liquid is safe for diamonds set in gold or platinum, and it handles most of the dulling you will ever see.

1. Soak the ring in warm — not hot — water with a few drops of mild dish soap for ten to fifteen minutes.
2. Brush gently with a soft toothbrush, paying attention to the underside of the stone where oils collect.
3. Rinse under clean water with the plug in, or over a bowl — never an open drain.
4. Dry and buff with a soft, lint-free cloth.

What to avoid

• Harsh chemicals — bleach, chlorine and abrasive cleaners can pit metal and loosen settings.
• Toothpaste — a common tip, and a bad one; it is abrasive enough to scratch softer metals and coloured stones.
• Ultrasonic cleaners on fragile or treated stones — fine for a plain diamond solitaire, risky for emeralds, opals, or anything fracture-filled.

If a stone feels loose, or you can hear it move, stop — that is a job for a jeweller's bench, not a toothbrush.

When to bring it in

Home cleaning keeps a ring bright between proper services, but it is not a substitute for one. Once or twice a year, have a jeweller check the setting, tighten the claws and give it a professional clean. It is usually quick, often complimentary for your own customers, and it is the moment a well-run jewellery house turns care into relationship.

If you are a jeweller, guides like this are also quietly good marketing: they answer what your buyers are already searching, and they bring the right people to your door. That is the thinking behind our jewellery marketing work.
