In its pure form silver is as soft as gold and so is alloyed with
other metals, usually copper, for strength. Silver is hallmarked
925 (92.5% pure), Sterling Silver or 950 (95% pure), Britannia
Silver.
Jewellery is mainly made from Sterling Silver. Items made from
Britannia Silver tends to be tableware.

Silver is the brightest reflector of any metal and can be polished
to a high sheen that even platinum can not achieve.
The finish on silver can be highly polished, matt or brushed,
satin, sandblasted or antiqued.
Silver is said to have a 'patina', a worn looking finish achieved
through frequent use and handling.

Silver does require more attention than gold or platinum.
Silver reacts with the ozone and sulphides found in the atmosphere
around many cities, which form a black film on the surface called
'tarnish'.
Tarnish can be removed by tarnish removing solutions and dips.
However these chemicals can also damage gemstones set in the silver.
Andrew Berry Jewellery sell special cloths that polish silver
without endangering gemstones.
