With gold the on-theme gift to give for your 1st wedding anniversary, this vintage farthing pendant dipped in 18-carat gold on a gold chain is an on-trend elegant fashionable choice. Small pendants on a chain are what we (women) are wearing out here now, often in layers with other chains as per our model. This necklace can be worn on its own too. 

The farthing coin is date 1942 and a farthing on one side and the king on the other.
