Hallmarking
Legally in the UK, any silver piece of silver jewellery weighing more than 7.78g, must be hallmarked in order to be sold as silver. Many of my creations weigh less than this, but I sometimes choose to get them hallmarked anyway (see individually listings).
Jewellers who use hallmarks, are reassuring you of the quality of precious metal they use, ensuring your chosen piece stays special long into the future.
You can learn more about what the hallmarks mean and why they are important in this pdf, or watch the video below.
