Silver Although
much harder than gold, silver can be easily worked and beaten into silver
leaf for decorative use. And just like gold it is long lasting and
hard-wearing. Silver
has been used in jewellery and coinage throughout the ages in the form of a
silver alloy. The fineness of silver items is measured as a proportion of the
silver content. For instance, Sterling silver has a fineness of 925,
which is to say that the silver content amounts to 92.5% of the piece. The
other metal content of silver alloys used in jewellery is usually copper.
Most silver jewellery has a fineness rating of 800, so there is 80% silver
content and 20% copper in most silver jewellery. High
silver content is also evident in white gold. The gold content of white gold
usually amounts to just over half, with silver amounting to one quarter of
the content. |
