Black Lip Oyster
Pteria Penguin is a genus of winged oyster closely related to Pinctata that also produces commercial quantities of pearls. Winged oysters are edible but unpalatable, and seldom produce precious pearls. It is a tropical species, with pearly interiors and long, wing-like projections of the hinge, have fragile shells. Winged oysters are found naturally on rocks and coral near channels and capes where the current runs fast and they attach themselves to the ocean bottom and to wharf pilings. Ptaria Penguin is a major source of Mabe Pearl production. Mabe pearls have a characteristic semispherical shape and unique rainbow-like luster and are a cultured half pearl, formed by inserting a half-sphere between the mantle and the shell. Since Mabe pearl oysters do not clump and their population is small, it is difficult to obtain a lot of mother oysters. Pearl culturing using natural oysters was conducted on a small scale. The first established artificial breeding techniques for the Mabe pearl oysters were established in 1970. The Mabe pearl oyster, Pteria Penguin that grows up to 20-30 cm in diameter is also called “the penguin wing oyster” from its shape like a wing. They commonly display a silver color under the oyster muscle with a rich mauve, gold banding towards the black/brown outer-lip. All semispherical “half-pearls” used to be called “Mabe”, however, only pearls come from the Pteria penguin are called “Mabe pearls” now. The Mabe oyster produces a brilliant nacre with a rainbow-like spectrum of hues, and the Mabe pearls produced from this nacre, which sizes are 12-20mm in diameter, possess a uniquely penetrating brilliance, with hues ranging from light pink through deep rose-red to a "rainbow" pink. Sometimes the pearls have gold-pink or other hues of high rarity. This rich variety of lustrous hues combines with nacreous layers of a rarely seen fineness of texture to give the Mabe pearl its perennial appeal and make it our original, popular product. Habitat It can be found from the Red Sea in the east to the western tropical Pacific and from the southern islands of Japan in the north to the southern waters of Australia. Mabe pearl producing countries are Japan, Hong Kong, Indonesia, Thailand and Malaysia.
