From the mind of a graphic designer comes the quirky jewelry collection by Joji Kojima. Lady Gaga’s celebrity has helped elevate Kojima’s work into a fashion sensation after she wore his chain mail mask on the cover of her multi-platinum Fame Monster album.

Find and buy these items at Tokyo-based retailer Restir.
