I was able to find a pair of these beautiful, detailed enamel hearts and fell in love immediately! They feature slightly translucent "Plique a Jour" enamel in a deep burgundy color and are set with diamonds on one side. There is light wear to the enamel commensurate with age but overall are in excellent vintage condition.
