wholesale piercing jewelry china The preliminary judgment is like "quartz rock jade"
ership is a dense block composed of granular quartz collection, with a quartz content of more than 90%. In addition to the quartz, it also often contains minerals such as chromium cloud mother, silk cloud mother, lithium cloud mother, red iron ore, and blue glitter. When the quality is pure, the quartz rock is white, the hardness is 7, the hardness is the same as the jadeite, the density is about 2.65, the refractive index is about 1.54, and the glass luster. Because of its dense and delicate texture, beautiful colors, high hard changes, high height, luster, good polishing performance, and a certain degree of transparency. Material. It is white from Xinjiang and is called Xinjiang Baiyu. The color produced in Myanmar is similar to jadeite, called Xincui.
The quality of quartz rock stones is mainly evaluated from the aspects of texture, color, transparency, impurities, cracks, etc., usually the jade is delicate and dense and uniform. There are less sandy eyes or the naked eye is not easy to find. Those with less impurities and cracks are better. Among them, the best green varieties are the best. In addition, the purple quartz jade and pure white Yingyan jade with fine colors and delicate texture are also top.
. Different origin, the texture and color of quartz rock quality jade often have different characteristics. According to the place of origin, it is divided into the following varieties:
1, Beijing white jade
is a kind of pure white and delicate texture, which is named after being found in the Xishan area of Beijing in the 1960s. Later, similar white quartz rocks were also found in Hunan and other places. In order to unify the name, some experts suggested the use of the name "Crystal White Jade" to show the characteristics of quartz, which includes white quartz rock jade from various real estate.
Ding white jade is a relatively pure quartz rock. The content of the quartz (SIO2) is more than 95%, and the color is uniform. Gray tone, no impurities. Quartz particles are small, and the particle size is generally less than 0.2 mm. The texture is delicate and slightly transparent. For those who are good, they are as white as sheep fat after polishing, but they are not as good as sheep fat jade, and they are crispy without the toughness of sheep fat jade.
2. "太 太". It is understood that "Sai Tai Cui" was formed from 1.8-24 million years ago. It was a rough jade variety among Chinese jade species, which was similar to emerald. The narrow sense of Taicui mainly refers to the jade mine produced from the town of Daxian Town, Urate, with emerald green, white, and cyan basic colors. This jade is produced in the Grand Pacific area of Urateqian Banner, Cuban, Inner Mongolia. The jade mine has been proven 41,900 cubic meters. With the continuous excavation and mining of new ores outside Da Shengtai Town, the general sense of Tai Cui already included similar quartz rock jade in the surrounding mountains.
3, dense jade
is named after being produced in Mi County, Henan Province, and is also known as "Mi County Yu", "Henan Yu" "Henan Cui" and so on. Miyama jade is very small, so that the naked eye is difficult to identify, so it is as delicate as nephrite. It is often slightly transparent to translucent. The colors of dense jade are mainly green and orange -red, but the master is green. Its green is usually apple green, which is more dark green than jasper, worse than jadeite green, and often changes in color shades, that is, how much the green scales -shaped silk cloud mother is distributed, and the green depth of green shades is displayed. When it contains or less, the jade is white. Usually the green of dense jade is lighter than the dark green Dongling.
4, Guicui
produced in Yonglong County, Guizhou Province. It is a fine grain quartz jade containing kaolin quartz. It is mainly a light green with blue and gray tone, and it is also green. Therefore, Guicui is also known as "Guizhou Jade". There are also gray -yellow and red varieties. Guicui's green is caused by the green kaolidic stone, so the color is not as bright as the mausoleum and dense jade, and there is no scales -shaped flash. The distribution of kaolin stones is uneven, so the color of Guicui also has uneven phenomena. Contains soft minerals such as fluorite, square lipstick, cloud paste, etc., jade is uniform.
5, Xincui
is produced in the mountainous areas of dozens of kilometers in Michiki, Myanmar. The pit is located in a mountainside area of more than 2,000 meters above sea level. It is often green or white-green. There are also red and yellow varieties. The proportion is between 2.0-2.3 and Mobi is about 7. The jade material itself is relatively transparent. Because it is produced in Myanmar and is close to the origin of emeralds, it has been mixed with emerald ice species for sale at high prices. Purple, light green, yellow, dark blue, etc. At the jade processing base, it is commonly known as "Xinkeng Emerald" (Xincui). It is mostly processed as a small jade jewelry such as bracelets and pendants. The cost is relatively high. The color of the jade material is relatively uniform, and the jade particles structure is relatively obvious. Compared with the old pit emerald, the jade particles are large and the structure is relatively loose. The internal quartz is dotted. Therefore, it is very distinguished from the genuine ice or ice -glutinous emerald. It was unable to issue a jade certificate due to large differences in the texture of the texture, and later that many authoritative institutions were jointly determined that it should belong to the quartz and rock jade.
6, Dongling stone
originally refers to a green quartz rocky jade produced in India, so it is also called "Indian jade". Because the jade contains the silk -like green chromium cloud mother scales, the Dongling Stone has a shining feeling, and the color is bright, it is green or blue with blue or blue, which is very beautiful.
In fact, "Dongling Stone" today does not only refer to Indian green chromium cloud mother quartz rock. The quartz rocks that contain colorful minerals and are beautiful and unknown are called Dongling Stone. As a result, there are green East Tombs, blue east tombs, red Dongling stone, and purple Dongling stone. The narrow "Dongling Stone" refers to the green chromium cloud mother quartz rock jade.
7, Tianshan White Jade
is produced in the Tianshan Mountains. It belongs to the quartz rock and is called Tianshan Baiyu. The hardness is 7, the hardness is the same as the jadeite, the jade is beautiful, the acid and alkali are resistant to acid and alkali. Fear sweat, white and clear, suitable for the sculpture of Buddha statues and pendant bracelets. Because Xinjiang is also called Xinjiang Baiyu.
80 was found in the Tianshan area of Xinjiang in the 1980s. Because the area in this area is located in the Tianshan Mountains, the quartz rock jade produced in this area is also called Tianshan Bingyu or Tianshan Baiyu.
In the test of the Jewelry Quality Inspection Center of Guangdong Province, the temperature of Tianshan Ice Jade is almost close to Hetian jade, and the transparency is close to Myanmar ice species and even glass species. The high -quality ice jade can see fluorescence under the sun, the refractive index is about 1.54. The hardness also reaches about 7.0, and the hardness is equivalent to the jadeite. Both flaws and cracks are rare.
A many players when they first met Bingyu, they would think it was the symbiosis of Burmese jade-Shuimo Jade, but it was not. It is not soft enough. Although it is also transparent in texture, it is always impossible to keep up with the good Tianshan ice jade. It can be distinguished by rough or finished products.
Due to the gradual depletion of Myanmar's jadeite veins, the production of white jade in the Hetian area declined, and the hype of Huanglongyu gradually calmed down; with the deep mining of the market and the continuous emergence of the outstanding works of Bingyu sculpture masters, Tianshan Mountains, Tianshan Mountains, Tianshan Mountains Bingyu has gradually become a new star in the Chinese jade market.
8, Qianjiang Daqianyu
, also known as Daqianyu, Yonghongyu, Minjiang Yu, Daqian Ziyu, Minjiang Shuiyu, Minjiang Caiyu, Yangtze Sister Jade, it is Sichuan Province The collective name of various seed jade produced in the Minjiang River Basin. Because the Minjiang River originated in Jiuding Mountain in Maoxian County, Sichuan, there are many tributaries and changes; there are many kinds of jade materials produced, and the color is thousands of color; coupled with the mainstream of the Minjiang River through the East Zhou Dynasty, Currently, the Ziyang area of Sichuan and the Neijiang area of Sichuan) and the famous Chinese painting master Zhang Daqian's hometown, Sichuan Province, Sichuan Province, so the jade materials produced by Jade are also respected by jade players as Lao Hongyu and Daqianyu. There are many types of jade materials in Minjiang, mainly because the source of the Minjiang River is complicated and there are many tributaries. It is not as clear as other rivers. Outside of the Minjiang River, the various seed jade materials produced by other tributaries also rushed into the Minjiang River with geological changes. The jade material passed through the rivers for tens of thousands of years, leaving only one quality seed jade, some high -quality seed jade It is as moist and transparent as water, and has rich colors. Therefore, the Qianjiang Qianjiang jade is also called Minjiang water jade and Yaojiang color jade. Moreover, the total length of the Minjiang River is about 712 kilometers, which is the first -level tributary of the Yangtze River.
In the test standards of the National Jewelry and Jade Stone (GB/T16552) and jewelry and jade identification (GB/T16553), the jade materials produced by Minjiang River regardless of chemical ingredients, physical characteristics (physical characteristics The hardness, internal crystallization state, and optical color characteristics) are all in line with the national test standards of natural jade, and have passed the identification of many professional authoritative testing institutions, and have obtained a national appraisal certificate.
It, because the Qianjiang Daqianyu is a jade material essence that has been washed through the river, nourishing soil and soil nourishment, and removing the essence, the value is much higher than the mountain material jade ore 5 5 5 5 To 15 times, some seed jade raw skin is generally left to indicate the identity of its seed jade.
