Lover’s eyes are hand-painted portraits on ivory which were popular in England between the 1780s and 1830s. The history of this jewelry style is as juicy as the paintings are gorgeous. Since romantic love didn’t typically exist within the confines of a marriage at this point in history, affairs were pretty common. So how would you show your loyalty to your lover? By wearing a sentimental portrait of an unidentifiable part of their person, of course.
