Anonymous users2024-02-07Ground color: also known as "base" color, which means background color, refers to other colors other than green, such as different shades of white, oil color, lotus root powder, gray, etc.;
Other characteristic parameters of jadeite are as follows:
1.Chemical composition: sodium aluminum silicate-Naai Si2
O6, often containing trace elements such as Ca, Cr, Ni, Mn, Mg, Fe, etc.
cas：1344-00-9
2.Mineral composition: jadeite is the main one, followed by omphacite, sodium chromium pyroxene, neite, hornblende, albite, etc.
3.Crystalline characteristics: monoclinic crystal system, often columnar, fibrous, felt-like dense synthesis, raw materials are lumpy, secondary material is gravel-like.
4.Hardness: 5Cleavage: no cleavage of fine-grained aggregates; Coarse particles can be seen on the section with shiny "fly wings".
6.Luster: grease luster to glass luster, high-end products are glass luster.
7.Transparency: Translucent to opaque.
8.Relative density: , generally grams per cubic centimeter.
9.Refractive index: spot measurement), with a vague shadow boundary near the refractometer.

Anonymous users2024-02-061. Green. Green is the common color of jadeite, and the "jade" refers to green jadeite; The green of jadeite is divided into light green, green, emerald green, dark green and dark green from light to dark, among which emerald green is the best; Most green jadeite contains more or less variegated colors, such as yellow-green, gray-green, blue-green, etc.
If the yellow tone in the yellow-green is very light and becomes yellow-yang green, it still does not lose the showiness of the jadeite, while the gray-green and blue-green will affect the quality of the jadeite color.
2. Purple. Purple jadeite, also known as violet, can be light purple, pink purple, purple, blue-violet, and even almost blue according to its shade.
3. White. The composition of white jadeite is single, but the structure is loose, there is a certain gap between the crystal mineral particles, and residual air or other substances reduce the transparency, making the jadeite opaque and white.
4. Black. There are two kinds of black jadeite: (1) it is black under ordinary light sources, and it is dark dark green when irradiated by strong light sources; (2) Jadeite with dark gray to grayish black, this black color is caused by the presence of dark minerals such as hornblende, which looks very dirty and is a relatively low-grade jadeite.
5. Colorless. Colorless means colorless and transparent; This kind of jadeite has a single composition, and the mineral particles are delicate, the structure is compact, the optical properties of the mineral particles tend to be consistent, and the transparency is good, such as the colorless old glass jadeite.
6. Combination of colors. In the jewelry world, some specific names have been given to some color combinations of jadeite, such as spring ribbon colored jadeite, Fu Lu Shou jadeite, etc. Spring Ribbon Color:
Purple and green, with the meaning of spring flowers blooming. Blessing, Lu and longevity: Green, red and purple exist on a jade at the same time, symbolizing auspiciousness and happiness.

Anonymous users2024-02-051. This color is closely related to the chemical elements and mineral composition of jadeite minerals, that is, the color formed during the crystallization of jadeite crystals. It is a relatively fixed color and cannot be dissolved with acid.
2. For example, the base color of brown tones and yellow-brown tones is often caused by oxides such as limonite filled in the gaps of jadeite particles. Light purple, light green and other hues are related to the chromogenic elements contained in the jadeite curved jade, and the blue-green hue is often related to the presence of a certain amount of iron or omphacite in jadeite.
3. The word Fei represents two colors, namely red and yellow, and the red and yellow colors are due to the fact that the jadeite enters the body of the jadeite in the process of formation, and the iron enters the body of the jadeite, resulting in red and yellow.
4. So how do you get so many colors? In fact, the color of jadeite is mainly caused by the substitution of trace amounts of CR, TI, FE, MN and other elemental homogeneous substances, the higher the content, the darker the color, and the less the content, the lighter the color.
Jadeite crystal pattern refers to the stone pattern on the crystal of jadeite. Stone grain refers to the small voids formed by the insufficient bond between the jadeite crystals, and such small voids are arranged in a linear or knife-like structure. If such tiny voids are arranged together in a clump or cloud, they become so-called "white cotton". >>>More
Glutinous is a term in the jewelry industry, waxy refers to the delicacy of jadeite jade, species refers to the texture of jadeite jade materials, jadeite texture is fine that is, the species is older or older, and the jadeite texture crystal is coarse and loose, which is called tender. Because jadeite jade is a combination of polycrystals, it is vividly divided into glass species, ice species, egg white species, glutinous species, bean species, etc. - Encyclopedia >>>More
This is the original version: according to legend, Zhu Yuanzhang, the founding emperor of the Ming Dynasty, once defeated Huizhou, Anhui Province, fled to the Xiuning area, starved in his belly, and ordered his followers to look for food everywhere, and an entourage found some leftovers, cabbage and tofu hidden in the grass by the fleeing people. Because there was nothing else, the entourage had to boil the leftovers, cabbage and tofu in water and serve them to Zhu Yuanzhang to eat. >>>More
The first method: tapping. Hanging the jadeite with a thin line, striking it with a confirmed natural jadeite, agate rod or other harder utensils, the sound of natural jadeite is clearer and more melodious, the echo is far away, the more delicate the germplasm, the clearer the sound, and the artificially treated jadeite has a dull sound, abruptly stopped, and there is no echo. >>>More
The identification of jadeite jade needs to be specialized in this industry, experienced people to identify, and there are many fake jadeite jade on the market.
