Are Cultured Pearls "Organic Real Pearls"?

Are cultured pearls "organic real pearls"?

  • The image below illustrates how a natural pearl is created. 
  • Pearls may be found in saltwater or freshwater.
  • Both saltwater and freshwater pearls may either be natural or cultured pearls.
  • Natural pearls are at heart all nacre, with no shell bead as its core.
  • Natural pearls are rare and costlier than cultured pearls by virtue of the following:
    • It takes a tremendous amount of time to raise these mollusks; and
    • No certainty that these molluscs will produce pearls successfully. Even if they do, resembling their mollusk counterparts, not all natural pearls will be of fine quality and desirable on every occasion.
  • For the reasons above, majority of the pearls that are retailing today are cultured pearls.

Cultured Pearl Farming

  • As above, a natural pearl is created when a mollusk coats the irritant with nacre as a response to it.
  • In a similar manner, a cultured pearl is created when a mollusk coats nacre around a shell bead that is implanted in the mollusk's tissues. 
  • This shell bead is also known as mother-of-pearl.
  • The shell bead is accompanied by a piece of mantle tissue during the implantation, which together, is the nucleus of the cultured pearl. 
  • Just like a natural pearl, a cultured pearl is also organic and real, with a catalyst and some helping hands.
