Overview On difference between natural, industrial and agricultural pearls
Pearls can be defined as an expensive and rare material, formed when an stimulant or irritable substance enters into a loose animal, where this mollusk secretes layers of aragonite and cocholin protein to protect itself, causing the formation of pearls, as any soft animal can form pearls, as the pearl oysters with golden lips or pearl oysters with silver lips are of the type of pinkada : Pinctada) located in Maxima in the ****** Ocean and Pacific from Japan to Australia is the most common in the pearl production process, this pearl is called the Pearl Pearl South Sea,and pearls are often used by jewelry designers to manufacture necklaces, bracelets, earrings, rings, and others.
The difference between natural, industrial and agricultural pearls:
Natural pearls, industrial pearls and agricultural pearls can be differentiated by:
It is a pearl that requires human intervention to manufacture where a person inserts a tissue or a bead into the molluscs, so that the mollusk deposits the layers around the material that the person has placed, forming a pearl similar to the natural pearl.
Natural pearls form a strange material to the body of the mollusk, and the animal lays down seashells to protect it from the natural pearls.
It is a pearl that nature has nothing to do with its manufacture and is entirely man-made.
Pearls used in jewelry:
Different types of pearls are produced from several types of shellfish, where each oyster lives in a different area from the other, living in different and very specific climatic conditions, and there are three main types of pearls used in jewelry and accessories, namely:
South Sea pearls.
Pearls are one of the rare gemstones, where pearls are made of natural and organic products of living organisms, and the quality and final size of the pearl varies depending on the climate factor and the nutritional conditions of the mollusk growth environment, the size and health of the molluscs that produced the pearl, and the size of the nucleus within the pearl, so the pearls have standards and standards to ensure their quality and value, including:
The size of the pearl is measured by the length of the pearl by the millimetre unit, and the size of the pearl ranges from 1 mm to 20 mm, and if all the pearl quality measures are similar and equal, the value of the pearl is determined according to its size, and the most common pearl sizes range from 6.5 mm to 11 mm.
There are many different forms of pearls, and the shape of the pearl depends on the shape of its component nucleus, and the position of the pearl inside the shellfish, where scientists divide the pearls into seven main forms:
They are all round and spherical pearls, and this type of pearl is very rare, and because of its rarity they are very desirable.
These pearls are completely non-round and non-spherical, they may be slightly stretched rather than fully spherical, yet they are classified as spherical.
They are semicircular pearls.
These pearls are oval in shape, with the ends of their ends narrower than the center.
Button pearls: Flat pearls that resemble buttons or discs, often used in the manufacture of earrings.
These pearls are pear-shaped or tear-shaped, and may be either long or short depending on the origin of the pearl, and this type of pearl can also be used in the manufacture of earrings.
These pearls are asymmetricand irregular in shape and can resemble a cross, stick or other shape.
These pearls are irregular in shape and can resemble a button or pearl drop.
The color of the pearl is based on its constituent dye, and the pearl color can be as follows:
Pearls colored in a transparent color.
Pearl shine or sparkle:
The pearl's luster or sparkle is produced when light travels through the transparent layers of the shell, and its reflection on the eye from the depths of the pearl.
Pearl surface quality:
The cleaner the pearl surface, the greater its value, and there are three types of pearl surface quality:
Light imperfections on the surface of the pearl.
Medium imperfections on the surface of the pearl.
Clear defects on the surface of the pearl.
The quality of the pearl's shell:
The shell is made of natural material resulting from the secretions of the mollusk, and the quality of the pearl's shell can be classified to:
The pearl has an indistinct core and has a very light flash.
A pearl with a visible nucleus.
A pearl with a pale chalky appearance.
Often there are no identical or identical pearls, so when searching for identical pearls, you should consider the factor of size, shape, color, and shine.
The most common sources of pearls:
The best oriental pearls are produced by mohar in the Arabian Gulf, with the largest harvest of pearls in the peninsula from Oman to Qatar, and other prominent sources of good pearls include:
Manar Bay, located between India and Sri Lanka.
Celebes in Indonesia.
South Pacific Islands.
Gulf of California.
Gulf of Mexico:
As for saltwater pearls, they are all cultured by the Japanese, who have mastered the cultivation of saltwater pearls, freshwater pearls are produced by the Chinese, and the quantities of fresh pearls are much larger than salt pearls, so their prices are much cheaper.
Information on natural pearls:
There is a lot of amazing information about pearls that many don't know, including the following:
Volume 0% pearls are the only gems created by a living organism.
China produces the majority of freshwater pearls, accounting for 95% of the world's total production.
Mussels can produce 30 to 50 pearls each time they are stimulated.
The annual production of diamonds is 10 times higher than the annual production of South Sea pearls due to its rarity.
A pearl more than 2,000 years old has been found in Western Australia.
In the late 19th and early 20th centuries, 50% of divers were killed in pearl extraction.
Natural pearl quality standards:
Here are a set of criteria for the trade-off between natural pearls and others, in terms of quality:
Shine is the most important criterion for determining the quality of pearls, the brighter the pearl looks, the higher its value.
Large pearls are rare, making the larger pearl the most valuable, if all other standards are equal.
It is difficult to get pearls completely free of lines and surface markings, but the sharper these lines seem, the less valuable the pearl is.
The colors of the pearls vary, with yellow, violet, blue, and other colors, and not only the dominant color of the pearl, but also the color of the transparent layer on its surface, as well as the reflected flash.
