You can get your diamonds cleaned at home - it does not always need a professional touch. Take good care of them - these are for a start - though you might need to get professional heavy duty cleaning done occasionally. Whatever be the case, regular cleaning will keep your brilliant stones sparkling and bright.
In a small bowl, mix some mild dishwashing detergent with warm water. Whip up some foam and lather. Dip the item to be cleaned into the solution.
Use a soft toothbrush and gently brush your jewellery and then rinse in warm running water. Pat dry - with a soft, fuzz-free cloth. Remember not to brush the diamonds too hard - you might get scratches on the gold/platinum/silver in which they are set.
Be careful that you don`t lose the diamonds when you are cleaning them in a sink - put a stopper in the sink before rinsing them.
Have your diamonds professionally cleaned about once a year.
