oklahoma jewelry wholesale The differences are: different shapes, different structures, and different colors.
The specific:
1. Different shapes
Natural pearls are abnormal in the nucleus, so the shape of the shape is poor, artificially pearls, and generally the nucleus is round. Bald beads.
2, different structures
The core of artificial pearls is artificially made, and the core of natural pearls is natural quartz sand particles or other substances.
3, different colors
The natural pearl texture, soft luster, high transparency (mostly translucent), artificial pearls due to short periods of pearls, loose texture, not strong luster, often on the surface, there are often available on the surface. "Small bags" commonly known as "Lianzi Bao" or "揪".
Extension information:
The pearl used as gems, generally can be evaluated and deleted from four aspects:
1, gloss, accounting for 40%of the price; 30%of the price proportion;
3, size, accounting for 20%of the price;
4, color, 10%of the price proportion;
Status, it is the key to determining the quality of pearls. The intensity of pearls can be roughly divided into three types of strength in the luster:
1, strong luster: appeared in the first -level pearl, the surface of the pearl is crystal, moist, and clear, and can see the object.
2, medium gloss: appeared in the second -level pearl, the surface of the pearl is basically clear, and you can see or partially see the object.
3, weak gloss: appeared in the third -level pearl, the surface of the pearl is pearl or weak pearl light.
southern jewelry wholesale 1. Different luster:
The artificial pearls are short in the age of pearls, loose texture, and not strong luster. On the surface, there are often "small bags" commonly known as "Lianzi bag" or "揪".
The natural pearl has delicate texture, soft luster, and high transparency (mostly translucent).
2, different structures:
The cores of artificial pearls are artificially made.
The cores of natural pearls are natural quartz sand particles or other substances.
3, different shapes:
If artificial pearls are generally rounded, so after becoming beads, there are often essence beads.
The natural pearl is not rolled in the nucleus, so the shape of the shape is poor.

If in 2008, my country has a classification standard for pearl quality evaluation, that is, "GB/T18781-2008 Pearl Tie" The thickness of the pearl layer thickness (with nuclear pearls) has made clear regulations, which gives people a clear basis for people's judgment of the quality of pearls.
1. There are many types of colors of pearls, mainly divided into five series of white, red, yellow, black and other series, and in each series, there are multiple body colors. Such as: the white series is divided into pure white, milk white, silver white, porcelain white, etc. When buying, the color is mainly based on consumers' own preferences.
2, the shape of pearls mainly contains round, round, nearly circular, oval, flat circular, alien, etc.
3, the longer the growth time of pearls, the larger the size, the less the value, and the higher the value. The size of the pearl is mainly expressed by its diameter. The size of the positive circular, circular and near -circular pearls is expressed by its minimum diameter, and other properties are represented by the minimum diameter of the maximum diameter.
4, "Pearl Treasure" is the most intuitive manifestation of the beauty of pearls. For a good pearl, gloss is its soul. Pearl luster is generally divided into four levels: strong, strong, neutral and weak, and divides the reflection capacity of light according to its surface.
5, pearls are the elves that are born naturally. There are more or less flaws on the surface. The completely flawless pearls are almost not existing. Common pearl defects include flowers, flower skin, threads, hair beads, etc.
6, the thickness of the bead layer refers to the vertical distance from the outer layer of the pearl to the surface of the pearl. The thin thickness of the pearl layer directly has a direct impact on the appearance of the pearl. The thickness of the bead layer is usually obtained by the professional laboratory or appraisal agency through professional equipment. The commonly used methods include X -ray phase method, OCT optical coherent analysis method Pearl layer thickness detection Methods and direct measurement methods.
holistic jewelry wholesale The difference is as follows:
. Different shapes
Natural pearls are formed naturally. The shape is not necessarily round, but it is more vivid. For the pearls of artificial cultivation, the kernel is generally round, so after the formation, the appearance is also round beads, which is slightly rigid.
. Different colors
The natural pearls have been formed for a long time, delicate texture, high transparency, and better gloss, while the pearls of artificial cultivation are short, the texture is loose, and the gloss is not strong.
. Different structures
Natural pearls are formed spontaneously in the body of software animals. The core is quartz particles or other substances, while the core of artificial pearls is manually made.
The maintenance of the expansion data
1. Anti -acid erosion: In order to prevent the gloss and color of pearls from being affected, pearls should be avoided to contact acid, alkali and chemicals, such as perfumes, soap, and set water. Don't wear pearl jewelry to swim or take a bath. So please put on your cute pearl after makeup.
2. Stay away from the kitchen: There are tiny pores on the surface of the pearl, so it should not be allowed to inhale the dirty substances in the air. Pearls can absorb eruption, perfume and other substances. So do not wear beautiful pearls to electrode, be careful in the kitchen. Do not wear beautiful pearls to cook vegetables. Both steam and oil fumes may penetrate pearls and make it yellow.
3. Cashmere cloth wait: After wearing pearls (especially on hot days), you must wipe the pearls after cleaning, and you can keep the gloss of the pearl. It is best to use sheepskin or delicate velvet cloth, do not use noodle paper, because the friction of some noodles will wear pearls.
4. Not near clear water: Do not use water to clean the pearl necklace. Water can enter the small hole of the beads. It is not only difficult to dry, but it may also ferment inside, and the bead thread may also turn green.
If you have a lot of sweat when you wear, you can use a soft and wet towel to clean it carefully. After the pearl turns yellow, it can be remedied like this: soaked with dilute hydrochloric acid, soluble the yellow shell, so that the pearl can reproduce the crystal gorgeous, glorious and charming color. But if the color becomes yellow, it is difficult to reverse.
5. Air: Do not put the pearls in the safe for a long time, and do not seal it with a rubber bag. Fresh air is needed between pearls, and every few months should be taken out to make them breathe. If the pearls in the box are easily yellow ("Lao Zhuhuang", this means it.)

wholesale sterling silver biker jewelry The difference between artificial pearls and natural pearls is as follows:
1, natural pearls are delicate, with uniform structures, thick pearls, strong luster, mostly dignified and translucent, mostly irregular shapes, small diameter; breeding pearls; breeding pearls; breeding pearls; breeding pearls; breeding pearls. Most of them are round, ellipse, water droplets, etc., straight supervisors? Pearls are thinner, pearls are not as strong as natural pearls, and there are often concave pits on the surface. The core of the beads is natural quartz sand particles or other substances.
3, pearls are formed naturally, the particles are not tidy, the rules are not enough, the round shape is less, there are fewer shapes, and the large particles are less.
4, natural beads (sea beads) are abnormally rolled in the nucleus, so the shape of the shape is poor; the beads are generally rounded, so after becoming beads, there are often essence beads.
Extension information:
The identification method of natural pearls and breeding pearls can be summarized as follows:
(1) The naked eye and zooming observation: the natural pearl is delicate, the structure is one, the pearl layer is thick thick , Strong luster, mostly dignified semi -transparent shape, mostly irregular shapes, small diameter; breeding pearls are mostly round, oval, water droplets, etc. On the surface, there are often concave pits, loose texture.
(2) Strong light lighting method: Natural pearls can not see the conditions of pearl cores and nuclear layers, and the consulted effect; Belt, most of the striped effects.
(3) X -ray photo method: Fake six -party symmetrical pattern spots appear in natural pearl Lauritu; spots with fake four -way symmetrical patterns in nuclear breeding pearls, only one direction appears fake in one direction, fakes appear in one direction Six -party symmetrical spots.
(4) UV photography method: Natural pearl shadow color is more uniform; nuclear raising beads produce dark shadows when the nuclear layer and light are vertical, and the surrounding colors are lighter.
(5) fluorescence method: Most of the natural pearls do not radiate under X -ray; most of the breeding pearls under X -ray most of the fluorescence and phosphorus (blue -purple, light green, etc.).
(6) endoscopic method : This method uses a hollow metal needle. It is equipped with a mirror with an extended direction of the needle at both ends of the needle, and it is 90 ° angle with each other. The light reflects to the inner wall of the pearl through the first mirror. If it is beaded, the light reflects to the parallel layer of the inner wall in the inner wall, which can always penetrate the thin pearl layer, so that the light can not be seen at one end of the microscope; if it is natural pearl, After the light was shot to the inner wall, the light was spread in the pearl layer due to full reflection, and finally projected to the second mirror surface. In this case, the light of light can be observed on the microscope at the other end.
(7) Magnetic field method: Put the circular pearl in the magnetic field. If it is beaded, the pearl nucleus is magnetized, and it must be transferred to the direction of the parallel layer and the magnetic line. Therefore, there is no such phenomenon
(8) heavy liquid method: Generally, beaded is pearl core, the proportion is large, and natural pearls are lighter. Therefore, most of the natural pearls in 2.71 are mostly floating. Shen. This method may damage the pearl layer, should be used with caution.

1, natural pearls are delicate, with uniform structures, thick pearls, strong luster, mostly dignified translucent shapes, mostly irregular shapes and small diameter; breeding pearls are mostly round, mostly round shapes, mostly round shapes, mostly round shapes, mostly round shapes, mostly round shapes, mostly round shapes, mostly round shapes, mostly round shapes, most of them are round. Ellipse, water droplets, etc., the pearl is thinner, pearl is not as strong as natural pearls, and there are often concave pits on the surface, and the texture is loose.
2. Natural pearls cannot see the conditions of pearl nucleus and nuclear layers, and the couplet effects; there are nuclear nursing beads, you can see the pearl nucleus, nuclear bands, and most of the stripe effects.
3, fake six -party symmetrical pattern spots appear in natural pearl Lauritu; spots with symmetrical patterns in nuclear breeding pearls, and fake six -party symmetrical spots appear in one direction.
4, the color of the natural pearl shadow is relatively consistent; there are dark shadows that have a dark shadow when the nuclear layer and light are vertically vertically.
5, most of the natural pearls do not fluorescence under X -ray; most of the breeding pearls are fluorescent and phosphorus light (blue -purple, light green, etc.) under X -ray.
The expansion information:
The formation principle
, external cause
1, the coat of the mussel is stimulated by foreign objects (sand grains, parasites), the epidermis of the stimulating point The cells are centered on foreign bodies, caught in the connective tissue of the coat film, and the epidermal cells that are caught in are split self -split to form a pearl sac. The pearl cyst cells secrete the pearl quality.
2, referred to as "nuclear pearls" with foreign bodies.
. Internal causes
1. After the outer skin of the coat is stimulated by pathological stimulation, part of the cell division is separated, and then the organic substances secreted by their own are gradually caught in the jacket connective tissue to form pearls to form pearls Sweet pearls are formed. Because there is no foreign body as a core, it is called "nuclear pearl".
2. The pearls of artificial breeding are based on the above principles, using artificial methods to cut the live epithelial cells (referred to as small cells) from the numerous mussel coat. In the connective tissue of the mussel film, small cells implanted, relying on the nutrition provided by connective tissues, rapidly proliferate around the artificial nucleus, forming pearl sacs, secreting pearls, thereby generating artificial nuclear pearls.
3, artificial nuclear pearls are only small cell slices when surgery of the outer membrane, forming a pearl sac by cell proliferation, and the pearl quality of the pearl of the capsule of the capsule.
