Quick answer: Soak your diamond ring in warm water with a little mild washing-up liquid for around twenty minutes, gently brush behind the stone with a soft toothbrush, rinse and pat dry. That is all most rings need to sparkle again.

Step by step

1. Fill a small bowl with warm (not hot) water and a few drops of mild washing-up liquid.
2. Soak the ring for around twenty minutes to loosen everyday residue.
3. Gently brush around and behind the diamond with a soft toothbrush.
4. Rinse in clean water — over a bowl, not an open drain — and pat dry with a lint-free cloth.

What should I avoid?

Avoid harsh chemicals, bleach, toothpaste and abrasive cleaners, which can damage metal and settings. Remove your ring before swimming, cleaning or using lotions.

How often should I clean it?

A gentle clean every week or two keeps a ring bright. For a deeper clean and a settings check, ask a jeweller. Read our full jewellery care guide.
