Nowadays, most pearls are cultured . This means they are real but not natural. An object is deliberately put inside an oyster so that it turns into a pearl, this takes about three years. They are still very beautiful of course. The first cultured pearls were produced a hundred years ago in Japan, and today most cultured pearls are still produced in Japan. There are also bigger pearls produced in the warm South Pacific and black ones from Tahiti. There are also some fake pearls for us to look at. To us, though, they look very similar to real pearls. Usually fake pearls are made from glass beads and have mother-of-pearl painted on them. This makes them lighter and much smoother . Real pearls are heavier and very slightly rough. When we nib the pearls along our teeth we notice that the fake ones are very smooth, like glass.
