Jade with lines refers to jade with lines and textures, which are generally presented in the form of lines and strips. This grain belongs to one of the characteristics of natural jadeite. This grain is formed when jadeite is squeezed by geological action, cracks are filled with foreign minerals and gradually heal.

Jade grain indicates that there are stone grains in jade, and jade grain indicates that there are knife-edge cracks in jade.

The texture of jadeite original stone is defined as the structure of rock academically, which simply refers to the direction in which jadeite crystals are arranged in long columns. Jadeite original stone was formed under high crustal pressure. In the process of formation, most pillars of jade mine grow in the direction of low pressure, just like grass in the rock extending out of the rock.

How to look at the crystal structure of jadeite and how to look at the crystals in jadeite.

1. Look at the crystal structure of jadeite, you can use a strong flashlight. Generally, after light inspection, natural jadeite will have impurities, defects, color roots and dispersion, while fake jadeite will not have defects and color roots.

2. Columnar metamorphic structure: The pyroxene minerals that make up jadeite have a high degree of automorphism, and the mineral monomer is generally rhombohedral, and the crystal cylinder, cleavage plane, double crystal plane and crystal edge are easy to identify with naked eyes or under a microscope. Large-size mineral crystals are often formed in the high-temperature environment in the early stage of mineralization.

3. Take the jade to a sunny place, but don't look at the crystal structure of the jade in direct light. The structure of jadeite is a crystal fiber interwoven structure. Under a certain light angle, there will be reflected dots, commonly known as jadeite, which is a typical identification feature of jadeite.

The jade bracelet can't see the internal crystal. What's the matter? Is it because the foundation is very thin?

1, buy a jade bracelet that is not particularly good in quality. The internal crystal structure is not so tight and loose. Therefore, if such jade is worn for a long time, its luster will deteriorate and its color will turn yellow, making the jade bracelet look blurred.

2. Cotton is a flaw in jade. Crystal sense means that the naked eye can see the crystal, which proves that the germplasm is very thick and there is no crystal sense, indicating that the whole crystal is still relatively delicate, only inside the bracelet, there are many defects like cotton.

3. No, you can see the crystal structure of Furong jade bracelet, which shows that the crystal structure of jade is thick and tender, and most of the internal ore bodies of jade bracelet are jadeite minerals.

Generally speaking, there are crystal particles on the jade bracelet, commonly known as flying wings, which refer to the jade surface. Under the illumination, the cleavage surface of jadeite minerals presents a bright white reflection surface, similar to the wings of flies. If it rotates under the light, the wings of flies in different parts will appear flaky flashes of different sizes, one after another.

Hetian jade looks like rice paste, because the crystal is fine and the color is even. Jade looks like the wings of a fly, some like a little ofloxacin, and some like broken glass. Because the jadeite crystal is not delicate enough, there are many colors on the same jadeite. 3; It's an appraisal of destruction. Set it on fire.

Explain what an emerald crystal is.

1, the crystal of jade is the composition and material of jade! Emerald has a different structure from other jades, that is, "emerald"! Structure (commonly known as "species" in business) refers to the particle size, shape and relationship of minerals, and the sum of structures constitutes the texture of a jade.

2. The crystal of jadeite refers to the cleavage of jadeite. Emerald has two sets of perfect cleavage of parallel cylinders, so it is called emerald because the cleavage plane reflects light. Jadeite is influenced by the crystal morphology and particle size of jadeite minerals. Columnar crystals are more obvious than granular crystals, and coarse particles are more obvious than fine particles.

3. The transparent lens in the jade bracelet is the granular crystal structure of jade, commonly known as "species". Reasons for the formation of jadeite: jadeite is a dense and massive aggregate formed by countless fine fibrous mineral crystallites, mainly jadeite.

4. Microcrystalline structure: The grain size of this type of jadeite stone is less than 0. 1mm, and the grain boundary is not felt by naked eyes, and the whole jadeite stone is uniform and detailed, with high transparency. The crystal morphology and arrangement can be identified under the microscope. This kind of structure is mainly composed of old pit glass species and ice species with good toughness.

5. The glittering crystal in the jade bracelet is commonly called flying wing. This crystal reaction is the green color of jadeite, and it is also one of the important signs to judge jadeite. "Flying wing" means that the surface of jadeite is bright white and reflective under the irradiation of light, like flying wing. To put it bluntly, it is a particle reflection.

6. The crystal of the jade bracelet after hand soaking is the crystal of jade, also called emerald. The main performance is that under the illumination, the crystal plane and cleavage plane will be needle-shaped and flaky, much like the wings of flies, so it is called fly wings.

Very smooth jade surface, but uneven under oblique light.

1, the "flying wing" of jadeite refers to the feature that the cleavage plane of jadeite minerals on the surface of jadeite presents bright white reflective facets like flying wings under illumination. "Flying wing" often appears in long strips or irregular sheets, which basically reflects the shape and size of jadeite minerals in jadeite and is an intuitive expression of jadeite.

2. It is not normal for jadeite to be unevenly polished. Jade bracelet, with the current production level, is purely machined, and there is almost no uneven polishing. The reason for uneven polishing is not production, but often jade.

3, jade polishing is uneven, in fact, you can choose to re-polish for processing. Generally speaking, jade ornaments will go through a process called polishing in the production process. Rough jadeite looks rough, the color is dim, and it is not moist at all. The polished jadeite has stronger stereoscopic impression, brighter color and more sufficient water head.

4. The surface of the jade bracelet is rough and not smooth, so it can be polished in a professional jewelry store. Generally, the grinding and polishing steps of jadeite bracelets include drum rough polishing, thread trimming, smooth surface trimming and shaping. Put the carved jade into the drum with a grindstone.

5. There are small pits on the plane of jadeite, which may be because jadeite itself is tender and has trachoma, so the polishing is uneven. It may also be because jadeite is mixed with minerals such as crystal, hornblende and albite. Because other minerals are not as hard as jadeite, they will sag and form pits after polishing.

6. Because rough grinding only removes large scratches on the jade surface, it is necessary to carry out fine grinding on the jade surface. If it is finely ground, it should be polished with fine sandpaper first, and then polished with cotton thallium made of sponge to make the jade surface smooth.
