Pearls are unique among gemstones because they don't arise from the depths of the earth but from the sea. They require no special cutting or polishing to maximize their lustrous beauty, which has been treasured since ancient times and ensures that pearl jewelry is always in style.

A pearl necklace is a slang term referring to a sexual act in which a man ejaculates semen on or near the neck, chest, or breast of another person. If ejaculation is onto the other person's face it can be called a facial.

Though classified as a gemstone, pearls are extremely unique, largely due to the fact that they are the only gem material formed and found within a living creature. Unlike diamonds, rubies, emeralds and more, pearls require no cutting or polishing before use and are simply stunning the way they naturally form.
