If you're on the look out for an unusual piece of vintage jewellery take a look at these Czech pin necklaces from Aquvii.
Not only vintage but well travelled too: the Japanese company has transformed a load of old Czech badges into chain necklaces. The badges feature a variety of emblems and themes, including the sporting shape of the design featured above.
The necklaces cost £15 each.
