A model opens a jewellery box, the camera focuses on a neckpiece and tries to catch the shine of the diamonds.

The cameraman shouts at the lights' man to throw more light. Unfortunately there is no shine because the piece has turned black!
Now imagine if this had to happen in real life, especially when you have a wedding to attend. Heaven forbid! Jewellery designer Amisha Khanna gives some tips to maintain the shine and lustre of your favourite piece of jewellery. . .

When buying any jewellery piece, check for its authenticity.

Always wrap jewellery in tissue or cotton and keep it in an air-tight plastic bag or box.

Polish gold, diamond or other semi-precious stones by soaking them in lukewarm water. Add one tablespoon of salt and detergent.

Brush gently with a soft bristle brush. This is the best home remedy to practise if you wear jewellery on daily basis.

Should you decide to hand your jewellery piece for polishing, ensure that the jeweller is reputed. Not doing so could result in the piece losing its purity.

Pearls are the most delicate of all jewellery pieces. Wrap them in cotton and store them in a plastic box. Avoid direct contact with perfume or cream. If you have sprayed perfume, wear your pearls after.

Perspiration could change the colour of gold. This also happens if the mixture of alloys is not right.
Rest assured, when you open your jewellery box the next time you know what to expect.
