How are pearls obtained?
लघु उत्तर
उत्तर
Pearls are precious jewels and the only gems created by a living animal. They are formed when a microscopic foreign object finds its way inside a mussel or oyster. The animal coats the object with a substance called nacre. With time, several layers of nacre build up over the foreign material thus leading to the formation of a pearl. These oysters/mussels are collected from the sea and opened to collect these pearls.
