This is one of the popular "Education of Eros" scene, where Cupid or Eros is taught by different Goddess on different theme. In this case the Goddess seems to be Hera, wife of Zeus, but it's not obvious what the education subject is, perhaps dancing?
In any case it is a classical mid Victorian heavy chunky cameo locket brooch. The frame is gilt, the back of the cameo set with a glass cover, the locket would have originally housed a picture or a lock of hair, it is currently empty where you can see through and see the carver's signature at the back of the cameo. The locket can be accessed by a jeweler if you'd like to put your own memorabilia in.
In wonderful condition, the glass cover moves a bit in the frame but is stable and secure, otherwise nothing to report. The original T-C pin back is in perfect working order. There is also a top loop where you can run a chain through to wear the piece as a pendant.
Measures approx. 2 3/8 inches by 2 1/8 inches.
