4 Major Types of Cultured Pearls

1. Akoya Cultured Pearls Akoya is one of the most common types of seawater cultured pearls, named after the Akoya oyster used. Developed by Mikimoto in Japan, it is also known as "Japanese cultured pearls." Akoya pearls are renowned for their perfectly smooth round shape, deep luster, and minimal imperfections, with sizes generally ranging from 3 to 8 mm, and rarely exceeding 9 mm. They are a popular choice for many women’s pearl jewelry.

2. South Sea Cultured Pearls South Sea cultured pearls are produced by Silver-lipped or Gold-lipped Oysters and can range in color from white to silver or gold. They are primarily sourced from Australia, Indonesia, the Philippines, and Myanmar. These pearls have a long growth cycle, large size, and thick nacre, typically over 10 mm, with shapes ranging from perfect round to fancy shapes like teardrop.

3. Tahitian Cultured Pearls Tahitian cultured pearls are produced by Black-lipped Oysters, resulting in their unique dark hues. Cultivated mainly around French Polynesia, with Tahiti being the most famous, these pearls are often referred to as "black pearls." They come in various colors, including gray, black, and brown, as well as lighter hues with blue, green, purple, or pink overtones, with the rarest and most valuable being "peacock green." Their size usually ranges from 9 to 14 mm.

4. Freshwater Cultured Pearls Freshwater cultured pearls are the most common type, with a wide range of sizes, shapes, and colors, and are relatively affordable. These pearls are mainly cultivated in freshwater lakes and ponds, with each mussel producing multiple pearls, primarily in China. Freshwater pearls are known for their diverse range and are a favorite among consumers.
