Diamonds seem to lose their luster over a period of time. Caring for them is essential to keep them bright and twinkling. With the right care, they will be your partners for life.

• Take half a bowl of cold water and add equal quantity of ammonia to it. Let your diamond soak in it for half an hour. Air-dry it and it will shine as if it were new.

• Another tip to clean it is to soak it in a bowl of water to which an ordinary detergent has been added. Use an old toothbrush with soft bristles to clean it and dry it.

• Get special diamond cleaning solutions and follow the directions carefully, so that you do not harm your skin.

Apart from these tips, it is essential to have them cleaned and the stones reset at least once in a year so that they are in a good condition.
