Silver Friendship bangle, handmade, hand-worked with slightly domed Silver wire, adjustable through pressure on the two knots.
Calling this clever adjustable bangle construction a Silver Friendship bangle comes from a stint in the 1970s in Tanzania where this same type of adjustable bangle, with exactly the same type of knots, was created using very tough natural fibres which were gifted as a so-called “friendship” bangle.
Whether the design originated in Tanzania is unknown, Whatever, it is a clever concept, works well as a bangle and should last the wearer a long time, given some care and no nasty accident.
