Warm water. Mild soap. Soft brush.
For most diamond and gold jewellery, a gentle clean is enough. Fill a small bowl with warm—not hot—water and a few drops of mild dish soap.
1. Soak briefly
Leave the piece in the solution for around 10–15 minutes to loosen oils and residue.
2. Brush gently
Use a very soft toothbrush around the underside of the diamond, prongs and small crevices. Do not force the brush into the setting.
3. Rinse and dry
Rinse thoroughly with clean water and pat dry with a lint-free cloth. Let the piece air dry completely before storing it.
