BLACK LIP OYSTER SHELL (Pteria Penguin)

Black-lip Oyster shell - Marta Howell Jewelry

Black lip oysters are winged shaped oysters that seldom produce pearls. The Black Lip is a tropical species with a pearly interior and long, wing-like projections at the hinge. The oyster produces a brilliant nacre with a rainbow spectrum of hues and colors. The oyster is a major source of mabe pearl production which are formed by inserting a half-sphere between the mantle and the shell.

Black-Lip Pearl Oyster Shell from the South Pacific

Pinctada margaritifera, commonly known as the Black-Lip Pearl Oyster, is a species of pearl oyster, a saltwater clam, a marine bivalve mollusk in the family Pteriidae. This species is common in the Indo-Pacific within tropical coral reefs.

The ability of Pinctada margaritifera to produce pearls means that the species is a valuable resource to humans. The oysters are harvested wild from coral reefs and are also commonly grown in aquaculture, both primarily taking place in the Indo-Pacific region.

The common name of this species refers to the fact that there is black coloring along the margins of the interior of the shell. Externally the shell is dark grayish brown or green, though white spots are common across the shell. Adults usually reach between 200mm and 250mm in height. A distinctive feature of the species is that the hinge has no teeth.

This species is commonly farmed and harvested for pearls, and there is general consensus that the quality of pearls from Pinctada margaritifera is the highest quality out of all the pearl oysters. Pearls form when a small particle enters into the oyster and nacre is released by the oyster to coat the particle or object, eventually creating a small pearl. The particle might be a grain of sand, organic material, or even a parasite. The oyster’s release of the nacre serves as an adaptation of the immune system to isolate the invasive particle and irritation. ThePinctada margaritifera in particular produces gray or black pearls.

PAUA ABALONE (Haliotis Iris)

Paua Abalone shell - Marta Howell Jewelry Information

The Paua Abalone are cultured for both pearls and mother-of-pearl shell but they are largely a by-product of the seafood industry. Paua, also known as rainbow abalone, is most commonly found along the shores of New Zealand. Paua are different from other abalone species by their bright, deep iridescent colors that are most desirable in rich blues, purples and greens.

Paua Abalone from New Zealand

In New Zealand, abalone is called pāua (/ˈpə/, from the Māori language). Haliotis iris (or blackfoot pāua) is the ubiquitous New Zealand pāua; the highly polished nacre of which is extremely popular as souvenirs with its striking blue, green, and purple iridescence.

Like all New Zealand shellfish, recreational harvesting of pāua does not require a permit provided catch limits, size restrictions, and seasonal and local restrictions set by the Ministry for Primary Industries (MPI) are followed. The legal recreational daily limit is 10 pāua per diver, with a minimum shell length of 125 mm (4.9 in) for Haliotis iris and 80 mm (3.1 in) for Haliotis australis. In addition, no person may be in possession, even on land, of more than 20 pāua or more than 2.5 kg (5.5 lb) of pāua meat at any one time. Pāua can only be caught by free-diving; it is illegal to catch pāua using scuba gear.

Pāua shells make up the decoration on Xena’s first chakram in the hit TV series Xena: Warrior Princess.[10] Although the show was set predominately in Ancient Greece, the shell is used because the pāua is native to New Zealand, where the show was filmed.

Tahitian Pearl Description

Assorted Black Tahitian Pearls in shell

The culturing process involves an expert grafter, who inserts a bead made from a mollusk shell into the gonad, or reproductive organ, of the mature Pinctada margaritifera mollusk. It takes two years for an oyster to mature enough to begin producing pearls. Inserted with the bead is a piece of mantle tissue from a donor mollusk, which influences the color of the pearl being produced and provides epithelial cells to ensure that the oyster produces nacre around the nucleus. The materials used in the process are organic, to decrease the probability of the oyster rejecting the nucleus.[1]The shell is sanded and rounded to form the bead, so the pearls produced have a rounder shape. The whole process takes place quickly, because oysters cannot survive very long out of water.[2] The cultured Tahitian pearl comes in various shapes, sizes, and colors; shapes include round, semi-round, button, circle, oval, teardrop, semi-baroque and baroque.[3] Because of their darker hues, Tahitian pearls are commonly known as “black pearls”.[4] However, Tahitian pearls have the ability to contain various undertones and overtones of green, pink, blue, silver and yellow. All (or any combination) of these colors may be seen in a cultured Tahitian pearl. Due to the variety of shapes and colors of the Tahitian pearl, it has been known to fit in any jewelry setting.[5] The versatility and mixture of color give it its value.

The Tahitian pearl is French Polynesia’s largest export, making up over 55 percent of the country’s annual exports of 20 million dollars.[2] The cultured Tahitian pearl farms are located in the blue lagoons of the TuamotuGambier Archipelago, which is one of the five archipelagos which make up French Polynesia (Tahiti is the main archipelago).[6]
