Among the cultured pearls, the most known and used are definitely Akoya pearls, produced for the first time in Japan and, for more than a century, unique among those cultivated. The diameter of these pearls range from 2 to 9 mm, with peaks of 10 for those of particular value and rarity. They are obtained by the introduction of specific nuclei within the Akoya oyster, which is found in abundance in the temperate eastern sea country. The natural color of these is the cream or yellow-green but with appropriate treatments you can get white, champagne, silver and pink. Also the forms may be changing, although the most common are those spherical. In some cases, you can get the twin pearls, since it is not uncommon to introduce two or more nuclei within the same shell. Over 90% of cultured pearls on the market belong to this variety.
The South Sea pearls, however, are considered noble pearls with a nacre layer very often and very homogeneous and with a diameter ranging from 9 to 17 millimeters. They can be black or white and have an excellent color, so much so that they are used to the natural, without undergoing any type of treatment. Black pearls belonging to this type are grown in the South Pacific area, so it is not unusual to feel reporting to Australian also with pearls term “South Sea”. They are much more rare on the market and prices are much higher quality of Akoya.
The freshwater pearls are cultured using the shellfish that live in salt water but not in lakes or rivers. An important feature concerns the increased quantity produced, given that the oyster can produce many pearls simultaneously. That’s why, with the same quality, the cost of freshwater pearls are lower than those of Bridgat who produce high quality pearl jewelry, including pearl earrings. The forms, as well as colors, are the most disparate: a rice grain, spherical, washers.
The Tahitian pearls, finally, there are the colors of gray, black, red, green, blue and brown and in numerous forms, but they are only a small part of world production, like what happens with the Australian.
Recognize A Real Pearl
It is not uncommon, at this point, wondering how to recognize a real pearl, natural or cultivated it, from an artificial. Of course, it’s always said that pearls should have a certificate of guarantee and authenticity but not everyone respects this good practice.
First, it must be said that the real pearls can be easily recognized by an expert through the use of appropriate instrumentation. With a simple X-ray photography, in fact, you can see the small nucleus at the center from which it was originated the natural pearl. The smaller the nucleus introduced compared to the pearl obtained, more of the same is of high quality. Of course, synthetic pearls will not present any core, since they are obtained by completely different procedures and not starting from the oyster producer.
Empirically, to recognize a gem should be enough feel its texture to the touch. If it is rough, not smooth and perfect, then it will certainly be cultivated, otherwise it will be concise without a doubt. Even nibble a pearl is a good trick: in this case, the roughness is the feeling that you’ll have to let you ride to identify its originality.
Pearls are very delicate jewelry, which require very special care. For example, you should never wear with perfume – very good advice in the case of earrings and necklaces – because the chemicals can alter the shine. Similarly, they should be cleaned with a soft cloth after use.
The pearl earrings are among the most used accessories also for their discretion, which is why, finally, recommend them without reservation to a young bride who wants to give an air of radiant, romantic and incredibly chic. You can also buy pearl earrings in combination with diamonds, a perfect accessory for the day of your yes.
