Pearls

   Description characteristic of the mineral.

   The marine (more regular shape) is known and river (usually less regular shape). Marine Pearls, the more so natural, but not artificially reared, extremely dear. Certainly, reared Pearls possesses mionectic capabilities, but, nevertheless, his work is saved. Natural pearl, abandoned on glass, jumps up once or twice, possessing a large resiliency. To the size of pea pearl grows for 12 years. Natural and reared Pearls has layers of growth and specifically caught for a tooth. Pounded in powder and inundated vinegar, selects the bubbles of carbon dioxide. Artificially reared Pearls usually has unpearl basis (metal, plastic, piece of mother of pearl from a shell) and layer of Pearls of 0,01-0.1-1 mm. Can be artificially painted. And Mother-of-pearl, Nacre (internal layer of shells of shellfishes), and Pearls consist of the thinnest plates of limeolith (aragonite), submerged in the organic matter of concholine. In spherical pearls these plates are located athwart surfaces, and in the mother of pearl they lie parallell. Due to it Mother-of-pearl, Nacre has more expressed game of paints and strong brilliance, and pearls look more mat as compared to the mother of pearl.

   Pearls - one of the most favourite century-old jeweller stone. It is used only on jeweller business. Zhemchugonosnye shellfishes are widespread both in salt and in fresh waters. Marine shellfishes give same the best Pearls. Shellfishes of Pinctada form large colonies in warm seas. They behavior the assidenous way of life, registering to the submarine stone. Life-span from 3 to 11 years. Pearls to 7 kg (not jeweller quality) make Tridacna mass gigas, mass of shellfishes arrives at 200 kg, and the size of shells arrives at 1,4 m. Dwells at the banks of Australia in Indian and in western part of the Pacific ocean. Trade of marine Pearls is very ancient employment, having more than 4000-years-old history. Collection of shellfishes is very hard and dangerous work. The fishermen of Pearls submerge from boats-canoes more than to one and a half minutes under water on a bottom exterminating, collect shellfishes in wire baskets. In a day they dive for 30-40 times. Ashore shells unseal and examine carefully. In the places of traditional catch of Pearls pearl appears only in one of 30-40 shells. Often in one shell there is one are three pearls, sometimes anymore.

   Important property of Pearls is his brilliance. Most brilliance with a mother-of-pearl ebb is characterize pearls of the Persian bay and bay of Manaar, I.e. pearls easterly - orient. In this connection the best sort of jeweller Pearls is named by oriental. Brilliance of Pearls is explained a refraction and reflection of rays in the prismatic layers of aragonite. Color of marine Pearls white, yellow, gold, cream, pink, rose, blue, red, black. An organic matter, present in pearls, can dry out and decompose, therefore Pearls has a certain term of life, it dims after, exfoliates, collapses. However at correct storage of Pearls loses the beauty during many years. Foremost, that Pearls not aging, it must be carried. In addition, it is not necessary to keep pearl in a too moist or dry place, long to hold them on a sun light. Dimming inexpensive Pearls can be for a while put into weak solution of vinegar acids.

   The cultivated is presently widespread marine Pearls. Stake artificially reared Japanese and in less degree 90% arrives at the Australia companies of Pearls and more. A size of large Japanese cultivated pearls 10-12 mm is a result of two- three years vital functions of shellfish. Large Pearls is cultivated in Australia. The measure of measuring of cultivated Pearls is a diameter of pearl in millimetres.

   Pearls appears in a clamshell, consisting of three layers: external organic - periostracum, built concholine, middle prismatic and internal lamellar - mother-of-pearl, consisting of prismatic and lamellar crystals SaSO3. Layers are formed the epithelial cages of mantle of shellfish and are an outward skeleton. These outward cages, gettings with a foreign body in more deep layers of mantle, create the special pearl sack (cyst) which serves as a ростовой chamber for pearl. The origin of Pearls can be examined as a protective reaction of shellfish on introduction in him of foreign objects. Enveloping their ephithelial cages, shellfish forms a organic-mineral aggregate with a concentric-zonal structure, including a kernel, prismatic and lamellar layers. A kernel is the center of crystallization of Pearls, it is surrounded the skim of concholine, which the prismatic crystals of calcspar, oriented athwart to the surface of layers, grow on. Each of crystals is surrounded a concholine cover. In marine pearls SaSO3 is 82-86%, organic matter 10-14%, water 0,5-4%; in freshwater SaSO3 - 5-95%, organic matter 4,5-95%, water 0,5-4%. The admixtures of microelements are possible. A form of Pearls can be different: correct spherical (round Pearls), oblong egg-shaped (oval), hemispheric (buttons), drop-shaped (pear-shaped), wrong (baroque). Shell Pearls appears near-by the wall of shell - containing foreign matters, and continuous - blister-Pearls (actually half of pearl).

In Ancient Rome Pearls was devoted the goddess of love to Venus. A ring with Pearls guards from thieves and from unhappy transactions. Him necessarily must carry Pisces, as he guards them from rash actions.
