Cultured pearls are divided into saltwater and freshwater varieties, each with its own unique characteristics.

1. Saltwater Cultured Pearls

(1) Akoya Pearls: Akoya pearls are one of the most classic varieties of white pearls. They are usually round, with colors ranging from white to cream, featuring a pink overtone and high luster. Their size typically does not exceed 9.00 mm.

(2) Tahitian Pearls: Tahitian pearls are the highest quality variety of black pearls and are commonly referred to as "black pearls." However, they actually come in a wide range of dark, cool colors, with greenish gray being the most common. Their size ranges from 8.00 mm to 14.00 mm (almost double the size of Akoya pearls). While they are most often round, they can also be found in other shapes.

(3) South Sea Pearls: South Sea pearls are the largest variety of cultured pearls, with sizes typically ranging from 8.00 mm to 18.00 mm. These pearls are usually white or golden in color and are known for their luxurious appearance. Like Tahitian pearls, they are most often round but can also come in other shapes.

2. Freshwater Cultured Pearls

Freshwater pearls come in a variety of colors and can have a metallic appearance. They also feature a wide range of pastel shades, primarily pink and orange. Their sizes and shapes vary greatly. Smaller freshwater pearls are usually non-bead cultured, while larger, round freshwater pearls are often bead-cultured.
