Just like gold, the silver used in jewellery is most often an alloy, which means the silver is blended with another metal before being manufactured into the beautiful piece of jewellery you wear.
In the majority of countries around the world, the standard for fine-jewellery grade silver is sterling silver, which is sometimes called 925. This alloy is made up of 92.5% pure silver, and 7.5% is another metal – most often copper. This alloy is created to increase the strength of the silver so it is durable to wear as jewellery.
Sterling silver is a great choice for jewellery, because it is durable and will give you lasting, beautiful shine. Because it has such a high percentage of precious metal, sterling silver is usually a safe choice for earrings for those with sensitive ears.
