This is a pendant my mother bought for me. It's of the three graces, Beauty, Charm, and Joy.
In Greek mythology they were known as Splendor, Mirth, and Good Cheer and were the daughters of Zeus and the nymph Eurynome.
They have commonly been an inspiration to artists and poets throughout the centuries. I love this necklace. It was hand made in Germany and is a two-toned agate of blue and white.
