How to identify true and false jadeite
At present, the jadeite on the market is indeed difficult to distinguish between fish and dragons. Many friends who love emerald often have such psychology, that is, sometimes I want to buy it and dare not buy it.The true and false jadeite is very important. Let ’s take a look at the true and false identification of jadeite with the editor.
The emeralds gloss is glass luster, and the reflective surface is as bright and sharp as glass.High transparency, glass -lustering jadeite is a popular emerald variety that is popular with people.B, C goods jadeite is not strong, and the luster like oil is not as bright as A goods.
The hardness of the jadeite jadeite is relatively high, and the glass can be easily cut, and the toughness is very high, and it will not break easily.The hardness of the jadeite after manual treatment will decrease, which is not as high as A cash emerald hardness.
The emeralds of jadeite are also known as "flies wings" and are one of the methods of appraisal of jadeite. When the particles that make up the jadeite are large, it is particularly obvious.If the particles of emeralds are very small, they are rare "green".After artificial treatment, emeralds have no "flies wings".
Emerald white cotton and white cotton refers to the internal plaques, strip -shaped, silk, and ripple -shaped semi -transparent, slightly translucent white substances.Although the existence of white cotton has more or less affected the beauty of jadeite, it is also one of the methods of jadeite, and the white cotton of jadeite also reflects the natural nature to some extent.If you see the pure jadeite without any impurities, if the price is relatively low, it must be manually dealt with, and you must be cautious.
The roots of jadeite are a sign of judging the authenticity of jade green green in the appraisal of jadeite. On a all -green emerald jewelry, see a little or a slightly darker green, and the slightly darker green gradient transition to relative transition to relatives.When the words are light green, it is called color root.However, high -end special jadeite, green is very uniform, there is no depth, there is no color root, and the root cause also affects its quality and price. Of course, the price of special jadeite is generally very expensive.Natural jadeite colors are colored, with tangible colors, uneven distribution, dyed emerald color divergent, invisible, floating, and is distributed on the surface layer.
A Hiring Standards of A Goods ① Special -grade: Green Green (Emerald Green), Apple Green, glass ground (translucent, delicate texture), uniform and bright, no impurities, no cracks.
② Commodity grade: green, oily land, slightly transparent, and transparent emeralds green pulse and spots.
③ ordinary grade: ravioli ground, bean green, light green, white delicate, slightly transparent.Occupible emerald, generally only jade jewelry.
A quality identification of jadeite ① texture.The natural jadeite texture is transparent or translucent, and the surface is oily and shiny. Observations are carefully observed. It can be seen that the nearly circular slightly transparent "salt particles" and fibrous substances around them.
② hardness.Natural jadeite is a rough jade, and Mos hardness is 7 degrees. It is engraved with sharp knife and will not leave traces; the fake jade has low hardness, and the knife can be engraved with traces.
③ Cui nature.Natural jadeite observes strong light. It can be seen that there are emerald flashes of other mineral particles, which are called emerald or green; the fakes made of glass, plastic, and porcelain have no such "emerald" features.
④ relative density (proportion).The natural jadeite structure is hard and tight, no bubbles, a large density, and the sound is crispy when knocking; the pseudo -structure is loose or has bubbles, the density is small, and the sound of knocking sound is hoarse and crisp.
⑤ color.The genuine green color is strong and pure.And some fakes are used with white jade, snake pattern, Australian jade, Korean jade, cloud stone, and even miscellaneous stone."In the strong light, the green lines can be seen, messy and small; although some do not show the texture, they are turbid.
Emerald A cargo identification skills 1. Eye feeling
1) Look at the colors of the color (natural and dye) of the color of the color (natural and dyeing) the color of the natural emerald color, the color is tangible, and the distribution is uneven;
2) Look at the transparency of transparency (planting water) natural emerald transparency, which is uneven, and the boundary line of transparency and opaque parts is clear;
3) Look at the surface luster, smoothness, and smoothness. The natural emerald luster is bright, the surface is smooth and round, the surface of B goods and covering jadeite is rough, and the luster is not strong.
4) Look at the degree of cleaning inside, a small amount of impurities in the goods, especially the dirty dirt and yellow -brown rusty color (secondary color). The B+B+C goods are clean inside, and generally there is no rusty color.
5) Look at the performance of emeralds, emerald green -the intuitive manifestation of the size and mutual combination of ligament in emerald.A, flies wings (emerald and counterfeit), emerald reflection is observed under the light, the rough surface of the rough surface can be seen below the reflection, which is "flies wings".On the smooth plane, through the lighting flashlight, you can also see "Flying Wing" B and "Orange Skin Effect". Natural jadeite is on the polished plane. Through reflective observation, it will show different protrusions and depression in different directions.——Pramma effect.The boundary line of the raised and depression of the A goods is gradually smooth.——Stility, through the lighting of side or bottom light, the internal structure of the emerald shows cotton flocculent substances, also known as "cotton".A cargo emerald "flocculent" is a long strip -shaped intertwine structure. It is relatively delicate.
6) Look at the craftsmanship.A cargo is thinner, good polished, B. B+C cargo is poorly worked, and the polishing is poor
Second, feel (hand oscillated and hand)
Hand: Large proper gravity, with a lot of hands, Saitama, Dushan jade, dyeing quartz rock, and water foam.
Hand rubbing: The surface of the A cargo is relatively smooth, the surface of the B cargo is relatively rough, and the jadeite and the coating emerald and have a sense of stickiness; the jadeite hand is obvious, and the glass is warm
Three, ears
The sound of the emerald of the A goods is crisp, like metal sounds, the bracelet has a sound, the bang B, other jade knocking sounds dull, and the bracelet has no echo.The most accurate method is to use the instrument for scientific identification.
