Need a little luck? This dainty horseshoe necklace might do the trick. If nothing else, it sure is a pretty addition to an outfit.
BONUS! It is adjustable in length. Look at the last photo to see how you can gently pull the chain through in either direction to achieve your desired length.
The necklace is a 17", 14k GF rope chain with a lobster clasp, and the horseshoe is approximately 11mm x 11mm.
