Tahitian Pearls Buying Guide
Tahitian pearls, symbols of luxury and perfection, are long sought for their exceptional beauty and value. Named after the tropical island of Tahiti, Tahitian pearls are valued as queen of pearls and creation of the sea. Tahiti’s black-lipped oysters yield a unique array of iridescent black, gray and greenish black pearls. Employing Japanese cultured akoya pearl cultivation techniques, farmers in French Polynesia began cultivating large black pearls in 1965. Nowadays, Tahitian pearl farming has spread over thousands of miles around this island. Due to Tahiti’s government promotion, demand for black Tahitian pearls rise 5-10% a year.
Tahitian Pearl Quality
Six factors determine Tahitian pearl quality: luster, nacre thickness, surface, color, size, shape.
1. Nacre Thickness
Nacre thickness is the most important factor when measuring Tahitian pearl quality. It determines how long the beauty of Tahitian pearls will last. Tahitian pearls with thick nacre will last a lifetime, while Tahitian pearls with thin nacre won’t last long; their nacre will wear off over time.
French Polynesia Government has set up a minimum nacre thickness of 0.8mm for Tahitian pearls. Tahitian pearls with less than 0.8mm nacre thickness are prohibited from exporting.
2. Surface Quality
There are four grades to rate the surface quality of Tahitian pearls: A, B, C, D. A quality Tahitian pearls are the highest quality and they are the most valuable.
A Quality: Tahitian pearls with very high luster and clean surface (one to a few slight flaws are distributed over less than 10% of the pearl surface).
B Quality: Tahitian pearls with medium to high luster and slight surface imperfection (some slight flaws are distributed over 30% of the pearl surface).
C Quality: Tahitian pearls with medium luster and medium surface imperfection (some slight flaws are distributed over 60% of the pearl surface).
D Quality: Tahitian pearls are heavily spotted (many slight flaws or several deep flaws are distributed over 60% of the pearl surface).
Luster is the best expression of a pearl's beauty. It is the quality of the light reflections from the pearl’s surface. Luster measures pearl surface shininess. High quality Tahitian pearls have high luster and mirror-like finish. Thick nacre results in high luster. Tahitian pearls with sharp and intense light reflection have high luster and a metal-like steely look.
Most common sizes for Tahitian pearls range from 8mm to 14mm. Some Tahitian pearls are 16mm and very rarely over 18mm. The largest Tahitian pearl in the world is 21mm for a round pearl and 25mm for a semi-round pearl. The larger the pearls, the more valuable the pearls are.
5. ShapeTahitian pearls have the following shapes:
Among all shapes, round is the most desirable and valuable. Other shapes may have special appeal to jewelry artists.Round pearls are almost perfect spheres. Round Tahitian pearls are rare and the production rate only accounts for 5-10% of Tahitian pearls produced each year.
Semi-round pearls are nearly round.Semi-baroque pearls are subdivided into four shapes: drop, button, pear and oval.
Baroque pearls are described as irregular shapes.
Black-lipped oysters produce the natural black color of Tahitian pearls. Although Tahitian pearls are famous for their black natural color, they have a wide range of colors including black, gray, blue, green and brown. These colors are referred to as body color. Body colors are enhanced by at least one overtone color. Overtone colors include blue, gold, silver, pink and reddish purple.
Different names are given to a combination of overtone and body colors:
Among these colors, peacock and Pistachio are the most popular colors. Tahitian pearls with peacock and pistachio colors have a higher value than pearls with other colors.
Buying Tahitian Pearls
When buying Tahitian pearl jewelry, color, quality, size, design, setting, and matching of Tahitian pearl jewelry need to be paid attention. Low quality Tahitian pearls (medium or heavy blemishes) are only worth a small fraction of top quality Tahitian pearls (flawless or very slightly spotted). It is important to ask the stores where you shop to provide detailed information on their Tahitian pearl quality.
