I have a plain silver necklace with a simple little horse standing that I wear all the time. It's like a little piece of the barn that I carry around with me! I also have 2 running horses that I sometimes put in as earings & I am now contemplating about starting a horse related charm bracelet or getting a horse hair bracelet from the horse I ride Moose!
Just to let you know...Epona was NOT originally a Roman Goddess. She is a Celtic goddess, and the ONLY Celtic goddess which the Romans adopted. Beautiful jewelery though.
