These three women are the daughters of Zeus known in Greek mythology as the Charites:
• Aglaia (Splendor/Radiance)
• Euphrosyne (Joy/Mirth)
• Thalia (Good Cheer/Youth)
Collectively, they symbolize everything that makes life worth living: charm, beauty, creativity, and friendship. In the Victorian and Edwardian eras, giving a "Three Graces" ring was a way to wish the wearer a life full of joy and social grace.
