Hetian Nephrite is divided into two categories: 'Mountain Nephrite' and 'Seed Nephrite,' with the Seed Nephrite being more desirable. Varieties of Seed Nephrite are: black jade, blue-white jade, green jade, mutton-fat Jade, tang jade, white jade, and yellow jade. Mutton-Fat Jade is considered to finest with a 'greasy' delicate texture and bright color. Chinese Hetian nephrite is nearing depletion due to over-mining, and as such it has become very valuble.When we talk about Hetian jade, no matter if it's from the royal family, folk collections, or the jade on display in the Forbuyden City, and no matter if we are talking about cultural heritage protection or how it comes into being, one can always feel a connection with the precious material. I think maybe it's because Hetian jade is so closely related to Xinjiang.Hetian in Xinjiang is famous for its high-quality nephrite jade, which is made up of tremolite. In terms of quality, the more tremolite there is the better quality the jade. Tremolite is transparent, so when it forms into ores, most of them are creamy white. However, Hetian jade comes in about seven different colors: creamy white, green white, green, blue green, dark green, red and yellow. Such diversity is caused by the volcanic eruptions. There's no tremolite on Earth's crust. Streams of lava which contain tremolite will mix with minerals when they flow from the volcano. Then the creamy white pure tremolite will turn into dark green with increasing mineral content."HeTian" JadeHetian jade originates from rocks residing at an altitude between 3500 and 5000 metres of mountains. After years of evolving and erosion, they are brought down into the river by rain, water, or movement of ice. In the fall, when the water level is low in the river, some of the jade pieces may be emerging from the water. The earliest record of the discovery for Hetain jade can be traced back to “Shanliao” period, when some Hetian jade pieces were unearthed in the grave of YinXuFuHao. The article entitled "Great jade Mountain of the Great yu Harnessing the Flood", Of Qian Long period of Qing Dynasty, really highlighted the highest perfection of jade art. The value of Hetian jade is depended on its purity of color and texture. It can be categorized mainly as following:(1)White Jade: it contains more than 95% tremolite. Its color is white, The texture is pure, exquisite, lustrous, and watery. It is the high-end category of Hetian jade. During the Han, Song and Qing Dynasties, it is the peak of the making of jade ornaments. During this period, white jade is a preferred choice of materials, and the high quality white was sometimes exquisitely called as "Zhongqi".(2)Mutton-fat white jade: it is the high-end class of whitejade with exquisite texture and high purity. It contains 99% tremolite. Its color is white, and has a lustrous appearance. Its value is much higher than white jade with the same weight. During the Han, Song and Qian Long of Qing Dynasty, the mutton-fat white jade was greatly cherished.(3) Light green jade: It does not have obvious distinction from white jade except that it has hues of light green in white. It is the third class jade material of Hetian Jade. The value of light green jade is a little inferior to the white jade. (4) Green jade: If the color shows light green, green and gray are all called green jade. It contains 89% of tremolite and 6% of actinolite. Its color is typically uniform and clear, the texture is exquisite, and it shows abundant luster. It makes the majority of Hetian Jade. (5) Yellow jade: Its texture is similar to white jade. Because it contains iron oxide, it has yellow hues in white. (6) Sugar jade: because of different content of iron oxide in tremolite, it forms red hues at various depth from the surface. (7)Ink jade: it has black color. (8)Jasper: It is produced in Zhunge'er jade mine. It is also called "Tianshan Jasper".Attention: for buyer from Russian Federation: The receiver name on your eCRATER address should be your full name .If not ,the post office in your country will return the item to china ,then you will lost it.The full name ,for example :Иван Иванович Иванов or the full name in English. so If the namePaymentWe only accept PayPal.PayPal is the only online payment method we accept.
