What is 925 silver?

Caravela Article no. 1 – What is “925 silver”?

“925 silver” is also known as sterling silver and put simply, it is an alloy of 92.5% pure silver and 7.5% other metal, usually copper.  The important thing for the customer to know is that it is used as standard measure of silver purity  and the 925 hallmark is recognised the world over as a mark of quality.

This silver alloy is much better for jewellery making than pure silver, which is a very soft metal and therefore less durable and more likely to bend out of shape.  Copper strengthens the silver and at the same time preserves its malleability making it ideal for jewellery making.  As well as making the metal more robust, a silver alloy makes the silver item more resistant to damage and scratching during wear.  At the moment, copper is the industry standard for blending with silver for a variety of reasons,  but a great deal of research and development is ongoing in this area and refining techniques are constantly being improved.

The term “sterling silver” is used interchangeably with 925 silver,  and it dates back to the 13th century.  It is believed that it comes from an old Norman word “esterlin” (star) and an Old English word “stiere” meaning “strong”.
