All items of sterling silver over 7.78g must be hallmarked in the UK. The hallmark applied to sterling silver is 925 indicating 92.5% silver content with the remaining amount consisting of other metals such as copper.
As with sterling, all items over 7.78g must be hallmarked in the UK. The hallmark applied for Fine Silver is 999 indicating 99.9% silver content.
Our gold items are usually 9ct gold and this will be specified in the individual item description. All items of gold over 1g must be hallmarked in the UK and for 9ct, the hallmark is 375.
