Tahitian: These are the dark group of South Sea cultured pearls derived from large, black-lipped pearl oysters which live in the waters surrounding Tahiti. Its nacre is usually a lustrous deep, dark green. Because of these characteristics, Tahitian pearls come in a variety of colours like black, green, gray, and bronze.

South Sea: South Sea cultured pearls may be easily distinguished from Akoya pearls by their larger size, usually ranging from 9 mm to 16 mm. Therefore, they are understandably the most prized of the cultured pearl types. The most popular colour is white and they come from the South-East Asia region.

Mabe: The mabé pearl oyster is found mainly in the tropical seas of South-East Asia and in the Japanese islands around Okinawa. The mabé oyster has a beautiful, rainbow-coloured iridescence that ranges from light pink through dark rose to slightly bluish shades, often with a metallic lustre. These mabé cultured pearls are half-rounds (with flat back), which has grown against the inside shell of the oyster.
