In recent times, the definition of vintage jewellery has broadened.  Jewellery used to be classified as vintage when it was 50 years old.  However, with the explosion of fashion jewellery in recent decades, costume jewellery is now more aligned with the cycles of fashion. Pieces are now usually classified as vintage when they at least 20 years old.

so for us the most modern definition of vintage would be early Y2K - an era defined by girlie sparkle and logos!
