It has an extreme shine. This is because it grows in cold seawater. The colder the water, the slower the mother-of-pearl grows and the finer-grained and more transparent it is. This is the main difference between "Akoya" pearls and cultured ones grown in freshwater. In addition, the color of freshwater pearls often has different shades. Usually, there are areas with a soft luster on the part of the pearls.
Sea pearls "Akoya" are made up to 10 mm in size. Prices rise sharply when the size increases by every millimeter, especially over 7 mm.
Akoya is a type of pearl that is found most often in jewelry. Its classic round shape, bright luster, and tiny pearls can be recognized. If you have a pearl thread, most likely it is Akoya.
Akoya is a cultured sea pearl. It is grown off the coast of Japan and other countries of the Asia-Pacific region on unique farms. Only here is it possible to maintain favorable conditions for Piccata Pinktada oysters?
For a long time, pearls had only a natural origin. Specially trained divers plunged to the bottom of the ocean to find an oyster with a precious pearl inside. Pearls were expensive, rare, and sometimes disastrous. Many of them died from caisson disease or accidents.
Everything changed with the advent of cultured pearls. In 1893, a Japanese man came up with how to grow a gemstone on farms under human control. According to one version, the name of the inventor remained unknown. However, the idea was picked up by a talented businessman Kokichi Mikimoto — the future "pearl king". He cultivated pearls by planting a small bead inside an oyster shell.
This invention revolutionized the jewelry world: pearls became affordable. Akoya began to appear in the collections of many fashion houses. By the 1920s, Coco Chanel proclaimed a string of white pearls as the leading women's jewelry, and this pearl was Akoya.
In the 1940s, US Army soldiers returning home from Japan brought gifts to their friends - long strings of Akoya pearls. These perfectly round pearls with incomparable brilliance have become the main accessory for
The legendary beauty of Akoya pearls is achieved by maintaining the correct water temperature and pH balance in the waters used for cultivation. This means that it can only be produced in certain parts of the world. Most of the acolytes are grown in Japan, China and Vietnam.
For the production of pearls, 1-2 round balls are implanted into the fabric of a pearl oyster. In response to the stimulus, the mollusk begins to produce mother-of-pearl, a shiny white coating that envelops the bead. The longer the pearl is produced, the more layers it will have. The bead remains inside as a core.
However, not all samples get to the jewelry market: more than 95% are rejected. It takes 1.5 years to create a pearl. In addition, the Picata Pinktada oyster produces no more than two pearls at a time, while some types of freshwater mollusks produce up to 50. All this causes the high cost of Akoya.
At first glance, all pearls are the same — both freshwater and marine. The difference is noticeable on closer examination: the Akoya has a more regular shape, a large size, and an intense shine. These properties are explained by the special conditions in which the pearl is bornю
the correct temperature and acidity of the water and a long cultivation period make it almost perfect.
Pearls of akoya happen:
Green, black, and other exotic colors are rare. If you see an unusual shade of Akoya, most likely it was painted.
The cost of pearls is also affected by the uniformity of their color. Since the pearl is in the oyster for 6 to 18 months, spots can form on its surface - from the effects of salt water, sand, and other factors: the fewer spots, the more expensive the sample.
Akoya pearls have an almost perfectly round shape. Because around the core is used in the cultivation process: mother-of-pearl envelops it layer by layer, preserving its rounded outlines. Symmetrical pearls are perfect for creating necklaces and bracelets.
Akoya is not only round. If desired, a shape nucleus can implant inside the oyster, and an asymmetric result can obtaine at the output.
The size of Akoya pearls varies from 2 to 10 mm. The average value is 6-7 mm.
Akoya is the most inexpensive sea pearl. However, it is much more expensive than freshwater: some copies cost thousands of dollars. The difference between an Akoya pearl necklace and freshwater pearls will be more than $500.
There are several international standards for the evaluation of pearls. The "Hanadama" method involves the evaluation of pearls on the A-AAAAA scale; the Tahitian system uses a gradation from A to D. The better the color, luster, shape of the pearl, the higher it is valued.
Akoya - pearls, as if created for long pearl threads and necklaces. The shape and quality of this pearl allow to quickly pick up identical specimens in color, luster, and other parameters. Pearls can be of different sizes, with a smooth or sharp increase in diameter.
The "correct" pearl thread must meet the following criteria:
* the thread of the base is in the tone of the pearls. It does not catch the eye;
* there are strong knots between the pearls;
* the lock is reliable and safe, but it is easy to open and close.
