Gold and silver are malleable and ductile, chemically stable by themselves
and can be recycled and remodelled into a multitude of items. Gold
retains its lustre over prolonged periods and will not chip, flake or
corrode. Highly polished silver is the best reflector of light and
retains its strength despite distortion. Unfortunately, this does not mean
that either of them are indestructible.Gold is measured in carats and is an indication of its purity. Most of us
discover the importance of gold ranges when we get married, and the
choices are usually from 9 carats (9ct), 18ct, 22ct and 24ct. However, the
purer the gold, the softer it is, until, in its purest form of 24 carats,
it becomes one of the softest metals known.Purer gold scratches and buckles easily with any kind of abrasion or force
and so is best removed to do work which might damage it. Equally, several
rings on the same finger can often be the cause of a ring suffering deep
scratches or wear, particularly if they are of different carats and
perhaps one or more containing even harder substances like diamonds.
