This piece is so of its time – likely late 1960s, early 1970s – that you have to love it just for being a perfect examplar of an age, borrowing a little bit from 1950s Sputnik designs.

True, the 60s and 70s are not renowned for spectacular jewellery designs, but there is something just joyful and fun about this brooch.

This is offered by Canadian Estate Jewellers. Currency is not indicated (guessing Canadian) but it sells for $1,349.
