Although diamonds are the hardest substance known on earth, they require care to preserve their brilliance. Diamonds have a great affinity to oils. Exposure during ordinary wear can dull the surface of a diamond. For example, lotions, cooking oil and products etc. Regular cleaning is important in keeping the diamond brilliant and refractive.
To restore the original luster, brilliance and fire of your diamond, soak it overnight in a solution of hand dishwash liquid and warm water. Remove it and gently brush it with a toothbrush, rinse it off with clean water and dry it with a soft cloth. Periodic ultra-sonic cleanings are also recommended (please check before doing this as some gemstones and settings may not be suitable) as are checks by your local jeweler for loose prongs due to wear. Always store your diamond jewelry in separate jewelry pouches for protection.
