Any piece of jewellery, whether it's an engagement ring costing thousands, a family heirloom or a sentimental piece of costume jewellery will last for many years if it is properly cared for. The cleaning and storing of your favourite piece of jewellery will not only add years of life to it but will save in repair costs and the heartache of throwing away a treasured piece of jewellery.

Even though you may wear your diamond rings all day every day, you should still give thought to its care.

Do not wear your diamond when doing rough work. Even though your diamond is very hear, it can be chipped by a hard blow.

When you are not wearing diamonds, they still need attention. Keep your precious pieces in a lined jewellery box or wrapped individually in tissue paper. Do not jumble then together as even diamonds can scratch each other.

Diamonds get smudged, soiled and dusty. Lotions, powders, soaps and even natural skin oils can affect a diamonds brilliance even chemicals in the air can discolour the setting. It just takes a little care to keep them clean.

1/ Mix a half and half solution of cold water and household ammonia in a small bowl. Soak the piece for 30 minutes then use a small brush to dislodge any dirt behind the stone and within the setting. Lift out and rinse well. Pat dry with some kitchen towel.

2/ Buy one of the brand name liquid jewellery cleaners and follow the manufacturers instructions. Do not touch clean diamonds with your fingers.

The same advice for coloured gemstones is basically the same for diamonds. DO NOT attempt to clean any gemstone using ammonia. They are several coloured gemstones that should NEVER be immersed in any cleaning solution. Your local jeweller is an expert and can advise you on your particular coloured gemstone.
