All of our hand stamped jewellery is made from 99.9% solid fine silver, with the exception of jump rings and chains, which are sterling silver. Current legislation states that silver items that weigh less than 7.78 grams do not need to be hallmarked but for any item weighing over this hallmarking is a legal requirement. At Hattie & Bella, our company policy is to only hallmark items over 7.78 grams. The majority of our items are below this weight, however, if your item is under this weight and you would still like it hallmarking, we can arrange this for you for an additional cost. Should you like your item to be hallmarked, please do bear in mind that your item will be sent away to the assay office which will lengthen the time in which you will receive your order by up to a further two weeks.
