What are the posts made of? I'm sensitive to some metals. The Celtic Crescent Stud Earrings are made entirely of sterling silver, posts included. Most people do not react to sterling, but always let your own experience guide you if you have had problems with silver in the past.
Who is the Celtic moon goddess? Strangely, there is no one single deity in Celtic mythology that fills the role of moon goddess. Arianrhod is one that is strongly associated with the moon and stars. Her name means "silver-wheel". Epona, the horse goddess, is another one with strong ties to the moon. Legends say that she rides a white horse across the night sky, galloping westward to avoid the rays of the rising sun.
