This is a unique pearl necklace with 32 exquisite pearls. A pearl is hard and rounded, it is formed by shellfish such as oysters. The pearl is formed when a grain of sand or other small particle accidentally enters the body of the clam and starts to irritate it. If the clam fails to expel the foreign body, it begins to secrete a special substance called nacre, with which it envelops it. Before the 20th century, pearls were mined only from the depths of warm seas, and the profession of pearl hunters was considered extremely dangerous. Cultivated freshwater pearl mussel plantations already exist, with their production accounting for over 90% of the modern pearl trade. The cultivation process itself was developed as early as the 13th century in Huzhou, China. However, the real success came only in 1924, with the discovery of the ikesho clam. Since then, the unique qualities of the freshwater pearl have been highly valued. Many superstitions are associated with pearls. In Ancient Rome, they were considered a symbol of power and wisdom, and for women they were carriers of happiness and voluptuous dreams. The Indians used pearls as talismans. Astrologers recommend pearl ornaments to those born under the sign of Gemini.
