Natural pearls are very rare in nature. Most of the pearls on the market today are cultivated artificially. To cultivate artificially cultured pearls, a small bead is implanted in the pearl shell. Over time, the pearl shell covers multiple layers of natural minerals and proteins on the beads. These coverings are called nacreous. It is true pearl that gives the pearl its beautiful luster and color.
