A simple tip which often eludes everybody is how to care for your pearls, corals, rubies, emeralds and other precious stones. Although this is a good practice to follow for all your non stone jewellery also. When you are getting ready to leave the house your jewellery should be the very last item you put on before you go out the door. Many people fall into the trap of putting their jewellery first and then spraying themselves with perfumes or hairsprays.
They being alcohol and chemical based can literally eat away the shine and substance of your jewellery, also if they are strung on silk thread it will cause it to fray and unravel. Along with this exposing jewellery to these sprays would also lead to tarnishing the soft glow of stones gradually fading their texture.
