How Do Oysters Make Pearls?

Did you know that How Do Oysters Make Pearls? If you don’t know then don’t worry because today we are going to discuss How Do Oysters Make Pearls?

Oysters belong to a class of mollusks called Bivalvia because of their hinged double shells or valves. Oysters have a soft and sensitive body inside their hinged shells. When a grain of sand or grit gets inside the shell of an Oyster and reaches the soft body, it starts covering the grain with layers of a hard smooth substance called nacre.

This is done to reduce the irritation caused by the grain to the sensitive body of the Oyster. A beautiful white silky round pearl is formed when many layers of this substance are produced by it.

To get more pearls, people started deliberately putting a grain of sand or a small bead inside the Oysters. The idea succeeded, and more and more pearls could be produced by using this method. These are called cultured pearls and are the same as natural pearls, the only difference being that the process of producing pearls is artificially or deliberately induced.

The main ingredient of the nacre which makes pearls is aragonite, a calcium carbonate distinguished by its orthorhombic crystalline system, its hardness and its special lustre and gloss. The colour of pearl varies with the type of mollusk and its environment. Colours can be found in ranges from black to white, as well as cream, grey, blue, yellow, lavender, green and mauve.
