Wearing a tiny portrait of your lover’s
eye on your jewelry was a secretive
romantic gesture in the 18th and 19th
centuries. When the Prince of Wales
fell in love with a catholic widow and
proposed by sending her a locket with
a painting of his eye inside, it wasn’t
long before it became a popular trend
to wear ‘Lover’s Eye’ jewelry on your
wrist or near your heart to symbolize
the love you have for another. SourceSource 2
