Tiffany & Co sterling silver pair of sneakers Keychain. This is missing the black rubber that formed the loop. The T& Co mark has been scratched off so the only marking left visible is the 925. 

This can be repurposed into a pendant and worn as shown. 

Measures 1.4 inches by 1 inch. 

Total Weight: 35.9 grams, so pretty solid for such a small piece. 

It is authentic and solid sterling silver which has been tested.
