Pearls have attracted people's attention since ancient times with their unique luster and elegant form. Whether it is used as an embellishment of jewelry or as a collection, pearls carry people's pursuit of beauty and picky about quality.<\/p>\n\n\n\n

Classification by place of origin :

1. Dongzhu: This is a natural pearl harvested in the Persian Gulf. The Persian Gulf is one of the famous pearl producers. The main molluscs that produce pearls are generally white in color and creamy white. It has a strong pearl luster with green color and a particle size of less than.

2. Nanyang Pearl: Generally refers to pearls produced in the South China Sea (including Myanmar, the Philippines, Australia and other places). The molluscs that produce beads are mainly Rctada maxima. Pearls are characterized by large particle size, round shape, thick bead layer, white color, and strong pearl luster. They are precious products in pearls.

3. Japanese beads: They are Japanese seawater-raised beads. The molluscs that produce beads are mainly Rntada funcata. They are now also produced in South Korea, China and Sri Lanka. Pearls are characterized by their round shape and white color, and their common size is 2~10mm.

4. Tahitian beads: Mainly produced in Tahiti, the French Polynesian islands near the Equator. The molluscs that produce the beads are Rnctada and marga\u02c9. The color of the pearl is natural black with a green backing color. It has excellent luster and a metallic luster. This variety is more valuable.

5. Biwa beads: They are freshwater cultured beads produced in Lake Biwa in Japan. The mollusk that produces the beads is Hyriopsis schlegeli. Pearls are characterized by oval shape and smooth surface. They are high-quality products for freshwater pearl farming.

6. Nanzhu or Hopu pearl: It is a seawater pearl produced in Hopu, Guangxi, China. The molluscs that produce beads are horse shells, large pearl shells, etc. Because of the good pearl-producing environment, the quality of the pearl is excellent, the shape is round, and the luster is strong. It is the crown of pearls in the world.

7. Beizhu: It is a freshwater pearl produced in the Mudanjiang, Heilongjiang, Yalu, Ussuri and other places in the north of our country. As early as the Han Dynasty more than 2,000 years ago, it was recorded that the quality of pearls was better than that of other freshwater lakes. After the end of the Ming Dynasty, due to the indiscriminate harvesting and harvesting, resources were wiped out. In the Qing Dynasty, the crowns, dragon robes and other ornaments in the royal family were decorated with Beizhu at that time, and Beizhu was also called \u201cDongzhu\u201d at that time.

8. Taihu Pearl: Taihu Lake is one of the important bases for freshwater cultured pearls in the rivers and Zhejiang in my country. The molluscs that produce beads are mainly mussel, especially the pearls cultivated with triangular mussels are among the best. It is characterized by less surface folds, soft roundness, and bright luster. In addition to the above-mentioned production areas, our freshwater pearls also come from Anhui, Hunan, Hubei, Jiangxi, Sichuan and other places.

9. Xizhu: Broadly speaking, it refers to pearls produced in the Atlantic Ocean, and in a narrow sense, it refers to pearls produced in the waters of Italy, mainly seawater pearls. Due to the increasingly poor local water quality, the production of Xizhu has become less and less.

Different types of pearls :<\/p>\n\n\n\n


(1) Seedless cultured beads: Insert small slices of the outer membrane taken from live mother-of-pearl mussels into the connective tissue of human sail mussels or other mother-of-pearl mussels, just as foreign objects in natural mother-of-pearl shells and mussels enter to produce seedless pearls that are basically the same as natural pearls.

(2) Nuclear bead culture: Plant the prepared bead nuclei in human shells and mussels, stimulate them to secrete nacre, and wrap the bead nuclei layer by layer to form pearls.

(3) Regenerated pearls: Regenerated pearls refer to when harvesting pearls, a wound is pierced on the pearl sac, the pearl is gently pressed out, and then the pearl-breeding mussel is put back into the water. After the wound heals, the epithelial cells of the pearl sac continue to secrete nacre to form pearls.

(4) Shell pearl: It is a combination of a hemispherical pearl cultured with a human nucleus and a mother-of-pearl shell. Bead nuclei are generally made of talc, wax and plastic.
