A lovely 18K yellow gold, diamond and ruby love pendant ("medille d'amour") with a rebus spelling out "Plus qu'hier, moins que demain" ("More than yesterday, less than tomorrow") a line from a love poem written by Rosemonde Gérard to her husband Edmond Rostand (author of "Cyrano de Bergerac") in 1889.
