To clean a diamond ring at home, the simplest and safest method involves using warm water, mild dish soap, and a soft-bristled toothbrush. First, soak the ring in a bowl of warm soapy water for about 15 to 40 minutes to loosen dirt and oils. Then, gently brush the diamond and the setting with the soft toothbrush to remove any remaining grime, paying attention to crevices. After brushing, rinse the ring thoroughly with clean water to remove soap residue, and dry it with a lint-free cloth or a soft towel. Avoid harsh chemicals like bleach or acetone, and don't use abrasive brushes or scrub too hard to prevent damage to the metal and setting.
