Seawater pearls are mainly divided into South Sea white pearls, South Sea gold pearls, Tahitian black pearls and Japanese seawater cultured pearls (also called AKOYA pearls). Except for the latter, the first three types of seawater pearls are relatively large, generally ranging from 9 mm to 18 mm, and even rare treasures exceeding 20 mm have been found.
South Sea white pearls come in white, silver and grey, and are mainly produced in Australia and Indonesia. South Sea gold pearls are mainly produced in the Philippines. However, biologically, these two types of South Sea pearls belong to the same pearl oyster: the white disc oyster. It is only the differences in environment and population that make the pearls different in color. In addition, there are also some gold pearls processed with chemicals on the market, so you should pay special attention when purchasing.
Next, we will introduce Tahitian black pearls. Although they are black in color, they have a variety of colors, and the most precious one is the "peacock color" with a hint of green in the black. The main production area of Tahitian black pearls is French Polynesia, and the shell is the black disc shell.
Whether it is white disc oyster or black disc oyster, only one pearl nucleus is implanted each time, and the culture is 2 to 3 years, but their lifespan is longer, so after the harvest, a new pearl nucleus can be implanted for a second pearl culture. Therefore, they can produce 2 or more pearls in their lifetime. Pearl knowledge cannot be blindly followed, only by visiting the pearl farm in person can you find out the truth.
