steel jewelry wholesale thailand The gravity: The weight is too light, so it must be fake, so that it can exclude imitations such as glass, plastic, pressure particles, etc., but now there are more crystals on the market. The weight is almost the same as the natural crystal. It is not easy to discover true and false.
The refractive index: Most people like to see crystals in the light, so that the true and false of the crystal can only look at the level of the crystal, because the crystal has a high refractive index. We can put the crystal in a darker place. The natural crystal color will be very bright. You can use natural white crystal and glass to feel.
Price: The crystal and the crystal of natural gems have one thing in common, that is, the crystals are extremely transparent, almost completely without stone patterns, but the price is far from the price. Usually, the crystal beads will be made into cut surfaces. The crystal is transparent, but the price is generally not too high. However, if he is really a natural gem level, the price must be more than 100 yuan, and the visual crystals must be determined.
The color difference: natural crystal color difference, a piece of natural crystal cannot be uniform in each part of each part, such as yellow crystal, and there are very few natural yellow crystals on the market. Natural yellow crystals can be distinguished in water. The color of natural yellow crystals in the water is uneven. Usually, a piece of color radiates to the whole crystal is yellow, and the crystal is definitely uniform in color.
the other: cold feel, crystals with stone patterns basically do not have false.
In inner bag: There will be no fakes if there are inner bags, so the crystal of hair crystals, ghosts and other connotation can be absolutely assured, because the cost of fake such things is very expensive and laborious. It's easy to be seen through.
14k gold jewelry supplies wholesale (1) Seeing:
This is the most important point when buying crystals, because sometimes because of conditions, we can only see it. Many buyers do not know how to choose crystals when they buy crystals. During the formation of natural crystals, the environment is often affected by the total impurities. When observing the sun, you can see a faint uniform and small horizontal or catkins. The fake crystals mostly adopt residual crystal residue and glass residue melting, which is made of polishing and imitation of color. There is no uniform stripes and catkins.
Melect the selection of ingredients: Sophisticated crystal products, you must not see the gaseous liquid bag of the star -like, cloud -like and flocculent distribution. The texture is pure, light, and crystal.
It look at the workmanship: the processing process of crystal products is divided into two types, namely grinding and carving. Such as crystal necklaces, bracelets, earrings, etc. belong to grinding products; Guanyin statues, inner painting smoke pots, etc. belong to sculptures. A well -working crystal product should be sophisticated, not only to fully show the external beauty (shape, style, symmetry, etc.) of crystal products, but also to maximize the excavation of its inner beauty (crystal, ingenuity).
It look at polishing again: The polishing is directly affecting the value of crystal products. The crystal must be pondered by King Kong Sands during the processing process. Rough production will make the crystal surface of friction. Good crystal products are naturally transparent and gloss.
It look at the hole eye: For crystal products (such as necklaces, bracelets, and Buddha beads), depends on whether the hole eyes are straight, the thickness of the hole is well -proportioned, and there are small cracks. The wall of the hole must be clear and transparent without "white marks".
In the color: Even in the same type of crystal, the texture and color of its different parts have each one. If it belongs to monochrome, the color is uniform; if there is a depth on the same crystal, it is required to be beautiful and generous.
The last look at the coordination: When buying crystal jewelry, you should wear it to see its size, tightness, length. If it is inlaid, see if it is firm, Zhou Zhenghe coordinated unity. You should also pay attention to whether the style of crystal jewelry and color are coordinated with your body, complexion, face -shaped Japanese JAPAN and clothing.
(2) Tongue licking: Even in the hot summer, licking the surface of the natural crystal with the tongue, it also feels cold and cool. There is no cool feeling of false crystals.
(3) Light: Natural crystal is placed in the sun, no matter from which angle, it can release beautiful glory. Fake crystals cannot.
(4) Hardness: Natural crystal hardness is high. Generally, crystals are used to gently draw on the glass (of course, you have to force), and you will leave shallow scratches; Maybe it is a fake crystal.
(5) Checking with polarizing mirror: Rotating 360 degrees under polarizing mirror has a four -day dark and four dark changes (dark dots appear every 90 degrees) are natural crystals. It is glass (artificial ones also changes light and dark, but the artificial ones are more colorful).
(6) Use two -color inspection: Natural amethyst has strong two -color, and false crystals have no two -color.
(7) Use a magnifying glass to check: Use a magnifying glass of more than ten times to check in the transmission light, and the obvious bubbles can basically be fixed as fake crystals.
(Checking with the hair: Put the crystal on a hair wire, and the human eye can see the dual shadow of the hair through the crystal. Double refraction (the results of the spherical crystal are obvious).
(9) Use the heat guide instrument to detect: adjust the heat guide instrument to the green 4 grid test gemstone, the natural crystal can rise to the yellow 2 grid , While the false crystal does not rise, when the area is large, it rises to yellow.
