Testing your metal

It's hard as nails


The gold, silver and platinum used in jewellery in the UK and the
US is alloyed. An alloy is a mix of metals, meaning it's not 100%
pure. The pure mined metals are very soft and can be bent or
scratched easily.

Testing your metal


So that we can make a more hard wearing yet still beautiful
piece of jewellery, we add other metals to the pure precious
metals in varying amounts. This results in dierent grades of
precious metals. So, for instance Sterling Silver, Fine Silver, 9ct
Gold, 18ct Gold and so on. These grades are stamped into each
piece of jewellery, called hallmarking.

We think of metals as being very hard wearing and up to a point
they are, but dierent metals have dierent properties and
levels of hardness. Nails and screws, for instance, are generally
made from a high grade steel and yes, they are very hard,
enabling them to withstand hammering into and holding other
materials together. But jewellery and other ne items made of
metal need special care. They're not as durable as you might
think.

In this little guide we'll deal with the metals most commonly
used for jewellery - silver, gold and platinum, although jewellery
is also made from palladium, titanium, copper, brass, bronze,
nickel, steel, tungsten, aluminium...

Alloy there!
