The Pacific Ocean is residence to the black-lipped oysters that make large Tahitian pearls. The ocean waters are warm, and this allows the oysters to expand significantly more substantial than in other areas, therefore producing greater pearls. Tahitian oysters are farmed in large sheltered lagoons that are held free of charge of air pollution and overcrowding. H2o temperatures and dietary levels, as well as environmental and biological situations are monitored carefully. These nicely cared for oysters are responsible for creating the lovely Tahitian Pearls.

How a Tahitian pearl is formed

Aragonite, which is a type of calcium carbonate, is secreted by the pearl oyster. This substance coats the inside of the oyster shell and makes the "mother-of-pearl" lining. It also types the layers of the pearl. The oyster can generate aragonite secretions up to four instances a day with every single secretion forming yet another layer. The layers are about one particular micron or 0.001mm thick. Tahitian oyster dwell for about two years which implies they generate up to about two thousand layers; more than most other pearls. The light passes by way of these several microscopic layers and is reflected and refracted to make a shimmering effect. This shimmering generates spectacular shades which look to travel and transfer all through the pearl. This is part of what can make the Tahitian pearl so unique.

Criteria

Pearls are graded based on particular criteria. These are:

o Size - the high-priced pearls are the larger ones. The Robert Wan Pearl is the greatest Tahitian Pearl and it measured more than 20.92mm or 13/16 of an inch in diameter. Tahitian pearls usually measure between 9mm and 14mm and are substantially greater than Chinese or Japanese pearls.

o Pearl Thickness - layers encompassing the nucleus.

o Shape - round pearls are the most sought soon after and can't differ a lot more than 2% from becoming properly spherical. Tahitian pearls can also be semi-round and semi-baroque.

o Surface Purity - surface imperfections on the pearl.

o Quality - the luster and the imperfections of the pearl.

o Brilliance - the orient and the luster of the pearl. The orient, which is the shimmering top quality of the pearl, is quite apparent in Tahitian pearls.

Colors

Although [http://tahitian-pearls.com tahitian pearls] are normally black, they are extremely special in their coloration. The pearls highlights can be silver and even gold. The overtones on a Tahitian pearl can be blue, purple and even green. The variations in the colors of the pearls make extremely striking jewelry when blended with other gemstones and metals.
