How to Tianhuang market

Factors that determine the price of the art market, there are many, one of which is a very important scarcity index, survive in the world less collections will naturally get a higher valuation, now almost depleted mining Tianhuang belong to this type. Reporters in Guangdong Geological Bureau Canton jewelry companies have found that the price per gram Tianhuang has grown from around 3,000 yuan in 2000, rose to currently more than 50,000 yuan per gram, or even higher, up more than ten years worth ten times . "Golden yellow" most expensive we often see some white, yellow stones, they are also called Tianhuang, but slightly lower price, the highest value in the end Tianhuang which color? Tianhuang not only yellow, and white, red and black. Which can be divided into yellow gold yellow, loquat yellow, yellow chanterelles, sweet-scented osmanthus yellow, orange peel yellow, cooked chestnut yellow, apricot yellow, yellow tung oil, wallets gold, of which the most positive loquat yellow, is Tianhuang Standard color; the "golden yellow" is the color quality tender spirit, golden light shines in bright light, very noble, but also the most expensive price. In addition, the white Tianhuang white field, gold package silver two kinds; red red orange peel red Tian Tian and simmer two, the former for the color, which is caused by external causes color; black have Kuroda, crow leather fields. Top Shoushan Ishida yellow is now the most expensive stones, fake more and more, is not necessarily to produce in Fujian Shoushan dickite, can be called tianhuang? Shoushan stone pit field can generally be divided into stone, puddles stone, stone Shankeng three categories. Tian stone pit which is that produced in the bottom of the river and the river on both sides of farmland Shoushan stone, field stone pit is Tianhuang main varieties. It should be said, it is a top Tianhuang Shoushan stone. The real Tianhuang must have such conditions: First, we must produced in Fujian Shoushan; second, components of dickite; third, limited color yellow, white, red, black four; fourth, delicate structure, dense, moist, this is the most important, is similar and nephrite seed material; fifth, Tian Huang stone is a natural oval, no obvious edges and corners; sixth, often with a carrot stripes, red muscle cells, stone skin three characteristics, but not absolute. "No skin is not a field" is misleading when many people buy Tianhuang are valued stone skin, it really is "no skin not field"? Due to the long buried in the fields, streams, in the long combination of factors of geology, physics, chemistry, Tianhuang original stone surface in direct contact with the soil, water and other external environment will inevitably change gradually, so as to form one or more layers of varying thickness stone skin. With the change of aesthetic ideas, especially with increasingly scarce and expensive Tianhuang retained stone skin, the use of stone skin color has become pretty mainstream. Reserved Tianhuang stone skin, using a thin carved Italian law, it is also possible to retain weight Tianhuang. It should be said, the vast majority of Tianhuang have stone skin, but also a small amount of Tianhuang no stone skin, "skinless not a field" argument is not valid.
