Abstract: It is an eternal truth that women love jewelry from ancient times to the present. Princess Diana once said, "If a woman can only own one piece of jewelry, it must be a pearl. Margaret Thatcher, who has a strong iron fist, is also a big fan of pearls. She said that there is nothing more eye-catching than pearls. Pearl is still out of date in today's market, but it has become a classic ornament and is widely welcomed by everyone. So, do you know the story behind the pearl? What are the pearls and shellfish produced? What shells produce pearls? Let's take a look with Bian Xiao. ① Hyriopsis cumingii Pearl: It is the main variety of freshwater cultured pearls, accounting for more than 95% of the market.

② Pinctada martensii: akoya pearl, which means Pinctada martensii, is very small, and 90% of the pearls cultured in seawater are Pinctada martensii. This kind of pearl is the most common cultured pearl on the market.

③ Penguin Pearl: It belongs to seawater pearl. This kind of pearl has large particles and is suitable for cultivating nucleated pearls or big shell pearls. The quality is good, but the output is low.

④ White butterfly pearl: It is the largest cultured mother shell in the world, and its size is 30 times that of marjorie, so it can generally breed larger seawater pearls. We often hear that white Nanyang pearls are produced in this shellfish, and the diameter is over10 mm.

⑤ Golden-lipped pearls: It is often heard that golden Nanyang pearls are produced here, which can produce golden pearls with different shades, generally more than 9 mm

⑥ Black butterfly pearls: relatively large, more than 90% are produced in Tahiti, French Polynesia. The pearls produced are black, gray, blue, green and brown. Because most of the colors are dark, people often call them black pearls, and the diameter is generally above 9 mm

⑦ Conch Pearl: It is produced in a large pink conch that lives in the Caribbean. Beads are usually pink with white or brown in the middle. They have unique flame-like surface traces, and the high-quality shape is usually oval with symmetrical sides.

⑧ Abalone pearls: The pearls produced by abalone are colorful, like the color of Aobao, and there are combinations of green, blue, pink and yellow. High-quality abalone pearls have high value.

Other mother mussels with different pearl yield include Pinctada plicata, Pinctada martensii, Pinctada maxima, Aleurites mollissima, Pinctada maxima, etc., which are not widely used and representative, and will not be repeated here.
