  • How are pearls formed?

  • It's a top secret.

  • I can't reveal it.

  • All right.

  • I will tell you.

  • Pearls are the result of a biological process within living sea creatures.

  • Like an oyster as it protects itself from foreign substances.

  • Wow

  • The oyster looks beautiful.

  • Indeed.

  • An oyster has two shells.

  • Inside the shells, there is an organ called mantle.

  • Mantle covers and protects all the internal organs of the oyster.

  • Whenever any foreign substance like a grain of sand or a parasite makes its way into the oyster.

  • Gets stuck in between the shell and mantle.

  • The mantle's natural reaction is to cover that foreign substance to protect the oyster's internal organs.

  • For this, the mantle secretes a mineral called nacre around the foreign substance in layers.

  • Over time, layer upon layer of nacre leads to the formation of a pearl.
