This is a single Edwardian horseshoe earring made from sterling silver. 
 
As many already know, horseshoes are symbol of good luck, apparently this reigns from when the eighth century Chaldeans thought its crescent shape represented various moon goddesses thus protecting against the curse of the evil eye. 
 
Whether you're wearing this as a talisman of good luck, or you have a special affinity with horses, you'll look chic and unique whether you choose to wear this alone, or as part of a curated stack.
