The four-leaf clover is special because it is very difficult to find, with only about one in every 10,000. Legend says that each petal represents a wish: love, luck, faith, and hope. This clover has one of those wishes engraved on it, luck.
It comes in two sizes. The chain is the same, only with different lengths. The clover has a hook that allows you to remove and attach it, so you can use the chain alone or attach any other charm from its ends.
For me, it is a necklace with a lot of presence and personality, for those occasions when you simply want to wear one piece that speaks for itself, even more than the clothes you are wearing.
