These genuine Freshwater Pearls measure [approximately] 8.5mm in length. A silver drop is secured with jeweler's epoxy to the top of this half-drilled, cultured Pearl. The leverbacks are made of 925 Sterling Silver, and are interchangeable. In other words, the open loop that the Pearl dangles from will allow for this Pearl drop to be removed, and be replaced by another earring dangle/drop, by just sliding it off over the top of the leverback. One pair of leverbacks that make it possible for you to change the earring dangles as often as you'd like. Your Sterling Silver Pearl Earrings will arrive gift boxed, and shipping insurance is included in the shipping costs.
