Sterling is the name given to silver products that are 92.5% pure silver. The term is originally based on English coinage and was only used in the British isles but over time it has become the predominant standard used globally. Our sterling silver (STS) beads offer spacers for all tastes and should be included in all precious metal bead collections. Once again we have a great range if matching STS earring and STS necklace components too.
