These gold rings were designed to be marked by the passing of time. When purchased, the rings have a thin outer layer of silver plating which, rubbing with time, shows the underlying gold band. According to the gold color, the people who wear the rings show this time has passed since their joining "the time shared between two people". Emotional value and durability grow over time as the gilded interior begins to shine through the silver plating.
