This expansion bracelet is unlike any you've ever seen! Four rows of silver-tone curved-top links set with diamantés stretch to allow you to put on the bracelet – it has no clasp. What's amazing is that the mechanism for stretching the piece – a series of springs – is concealed. The last photo shows part of the British utility patent for this construction. This bracelet is the only piece in this group with the 'SIMEX' trademark. I can’t figure out how to tell you the size of this jewel other than how it fits me. My wrist is 6 ¾”, and the bracelet fits me fine. It stretches to the diameter of the widest part of my hand – 8 ½” – that’s required to put it on.
