The formation of jade is very complex, be in early when Qin Shi emperor unites China, because He Tianyu originates in Kunlun hill to be called " Kunshan's jade " , later because be located in " Yu Tian country " churchyard and be called " Yu Tian jade " . Till clear Guang Xujiu year (1883) establish and when city of Tian Zhi be subordinate to, just be named formally to be " He Tianyu " . He Tianyu's history is consequently of long standing and well established.
One He Tianyu's breed is very much, it is in order to produce the seed material of border of make a fresh start and field zone among them best. The embellish of hill makings raw material that the characteristic of Xinjiang is much is spent very pretty good, bad is on whiteness at Qinghai makings and Russia expect. But the resolution that hill expects is general the person differentiates hard, and the standard that truly good seed expects ability is Xinjiang and Tian Yu.
2 Qinghai do not have seed makings, although Russian makings has but better also from leather color and quality of a material resolution, want to choose real estate of a Xinjiang " He Tianyu " of be the first to be affected is seed makings. With Tian Yu seed makings also is divided, 2, third class, qualitative finer whiteness jumps over the flesh tall child makings price also is higher, it is a lot of cheaper that sapphirine wants.
Fat profit of 3 seed makings, have leather quality, have pore, appearance resembles everybody's common cobble. 1 makings seeing seed should be watched above all whether to have pore, and pore is exquisite, pore the more exquisite basically the flesh is qualitative more exquisite also, if do not have pore to want to make a question mark above all, still a kind of seed that is the skin that grind sand expects. 2, pore and brightness all differ somewhat, and the tactility of begin also is met differ somewhat. 3, the pore that seed expects is mixed namely differentiate Pi Cao about the same, the natural pore of dermal grass is inherent, very difficult the day after tomorrow treatment comes out, but it is better that the pore of mimic has the law relatively differentiate. 4, play seed makings to answer as far as possible first the seed makings of color of skin of little contact belt. Of such your choices is Xinjiang real estate at least " He Tianyu " . is not a general designation " He Tianyu " .
4 from the point of leather color seed expects: 1, observe its true and false, seeing it is the skin of which kinds of material for making clothes. Observe its colour and lustre whether very gorgeous, onefold, also or it is to compare depressing, color to float in the surface, also feel without administrative levels, this can be a few features of leatheroid. 2, observation has cracked place, the material for making clothes of artificial chromatically, the colour and lustre that splits a share is met deeper. Have some of colored material for making clothes, its faded for some time, color looks so won't false, but it is more difficult to have cracked place fades. Because this painty meeting deposit is in a place, the colour and lustre of nature and other place is different, the brim color that and have cracks place is deep, go to li of color will be lighter. Natural seed expects an as it happens is contrary.
5 hill expect piece degree big, hill running water expects: Interpose expects at seed and the He Tianyu among hill makings, boil from hill fall in water to not was over completely degrade the He Tianyu of cobble appearance; Russian makings works to be not had in vain oily; Qinghai expects water is appeared; Han expects the structure is clear, waxiness feels strong; Guangxi expects material for making clothes is unripe, jade is changed not complete; The river wears jade green color onefold.
Anyhow, good He Tianyu seed expects, color of appearance, whiteness, skin, embellish is spent is nice gift say to go up high-quality goods. Seed makings is formed after the burnish with the ceaseless chiliad in riverbed erodes, an appearance is admirable and the seed material with less flaw, it is very god-given really, the price in the market very tall also.
