Care for your diamond ring

Clean the ring gently with mild soap, lukewarm water and a soft brush. Dry it with a clean microfiber cloth. Store it separately in a soft pouch or jewelry box. Remove your ring before strenuous activities, and avoid harsh chemicals and hard impacts. If a stone moves or a prong catches, stop wearing the ring and arrange a professional inspection.
