The principle of pearl formation, most people can say one or two: foreign matter such as gravel enters the mites, causing them to secrete mineral-like pearl-like substances containing calcium carbonate, that is, pearly, and form pearls.
However, scientists' research suggests that it is not the gravel that actually causes the scorpion to secrete the pearl, but the mites.
When mites discharged from large fish such as sharks are accidentally dropped into shellfish such as oysters, the secretions formed by the stimulation of the mantle film gradually smooth the foreign matter, and finally a crystal-clear pearl is born.
In fact, this theory was first proposed in 1852 by Philippe of Turin, Italy. Then, in 1903, Heidemann, a professor of marine biology at the Royal Society, published in his 1903 paper that aphids were formed. The point of view of the essentials of pearls.
Modern science has shown that there may be various parasites around the pearl, such as sea snails and fish, but the most common are aphids that are excreted by large fish. Shellfish can wrap any parasitic material and secrete thick pearls to trap the parasites in the airtight shell, thus completing the pearl.
For centuries, pearls have been seen as a symbol of wealth. Mikimoto Yuki, the inventor of artificial freshwater pearls, once said a famous saying: "I hope that pearls will one day hang on the neck of every woman. Many ladies and ladies in history have been fascinated by pearls all their lives." Well-known famous pearl lovers include Queen Victoria, Marilyn Monroe, Elizabeth Taylor and Princess Diana.
