Betty comden Either saltwater pearls or fresh water pearls can be natural or cultured. Natural means that there is no human intervention and the pearl is formed naturally by the oyster or mussel. The pearl oyster secretes nacre an iridescent material made of calcium carbonate. The nacre will coat a microscopic irritant entering its shell until a pearl is formed. On the other hand, cultured means that a pearl grower will carefully open the shell and introduce a small object as an irritant (commonly a bead or metal), then get them back into the water and wait for the pearl to form. This usually takes 2-5 years. luxury ski chalet french alps

Even "cultured" pearls are genuine pearls too, having an advantage of being more affordable than natural pearls.
