Tell about pearls of ocean
Answers
Answer:
A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite)[3] in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable.
Answer:
Pearls don’t need polishing or faceting to reveal their natural beauty. That’s why pearls were among the first gems worn by humans. The oldest known pearl necklaces graced the necks of women more than 4,000 years ago.
Some early stories say pearls grew from the tears of a goddess. Others tell of oysters swallowing raindrops or dewdrops that fell into the ocean. Round and lustrous, pearls symbolize the moon, and mortals have universally assigned feminine characteristics to them. Those who value gems for their powers wear pearls to attract love and good health.
Pearls are classified as organic gems because they are made by animals called mollusks. Mollusks have shells and most of them live underwater. They secrete a natural substance called nacre (rhymes with “acre”).
