Spring ring clasps (Bolt Ring)
Spring ring clasps are a pretty necessary part of any jewellers arsenal. They are relatively easy to use, while being incredibly robust compared to some types of clasp.
They have a small ‘switch’ or lever, which compresses a spring, drawing back a piece of metal that was covering the opening.
These clasps are sold by the size of the larger ring, to give you an idea of size. We will eventually make a sizing chart!
