Green Jade
Since time immemorial, jade has been closely associated with Chinese culture.
For the Chinese people, which has the power to protect body and spirit of the living and the dead, but also treat it as talisman. In the West, jade is sought after for its elegance, the mystique and romance.
href = "http://www.chowsangsang.com"> Jade can be classified into two types, jade and jadeite. These two minerals totally different. Colors include white nephrite opaque, yellow, green, black and color is always evenly distributed. Jadeite colors are white, purple, yellow, Green and others, uniformity of color varies with different textures.
Most are produced in China jade jade. Among the most prized pieces of jade are some describe as "mutton fat". As the description indicates, these are pieces of creamy white color and transparent. Most thin carved jade objects are made of jade.
Jadeite occurs mainly in Burma.Since jade is more prominent in different aspects, such as texture, color and price, is used almost exclusively in the establishment of jewelry, which also lead to increased market demand, so we limit our discussion to jadeite.
Jadeite is also known as Fei Tsui. The criteria used for recognition are: color transparency, clarity, cut and defects.
COLOR
The color is of paramount importance. Examine the color of Fei Tsui according the following criteria:
1.Purity
Clarity refers to the proportion flower and secondary colors. Fei Tsui green Take as an example, the most desirable is pure green, in descending order of desirability are green tinged with yellow, blue and gray.
2.Intensity
The more saturated the better the jade green. However, an exaggerated intensity is only the quality is average.
3.Vividness
The color should be dynamic and alive. The presence of gray and black makes the dark green, without altering its hue.
4.Evenness
The further color, jade and more desirable the higher the value.
TRANSPARENCY
Fei Tsui Transparency affects the refraction of light and beauty. When light enters a transparent process with Fei Tsui fine texture, shine, and if the light enters an opaque Fei Tsui coarse textured, soft light that refracts the which reduces the appeal hearing.
CLARITY
Clarity refers to inclusions that cohesive with jade during the training process, mainly black and white. In general, white inclusions are less dramatic than those of black and of course, the least visible of the inclusion of the best.
CORTE
Fei Tsui is usually worked into two categories: plain polished shapes such as cabochon and carved designs. Plain polished shapes require higher grade material without defects, and with good proportions, symmetry and the appropriate thickness. For example, a well-cut cabochon should be neither too thick nor too thin in relation with higher surface area. His "package" should be centered, important but not overdone.
Printed designs are often used to remove or minimize the effect of faults and cracks. Are assessed by their aesthetic and finishing details.
VICES
An error value are the lines of detractor Fei Tsui tsui.Fei can be raped and even break when it crashed. We can use a torch to examine the cracks and defects and that consumers should pay particular attention to making the purchase.
High quality jade can be sold at an affordable price, however, has a limited supply. To maximize profits, some employers continue artificial jade treatment before being put on the market. Jade is then classified as "jade A", "B" jade and "C" jade.
Jade Treaties
"C" Jade
"C" jade is dyed jade. During the treatment process, the dyes Jade colorless injected into high temperature and high pressure environment. The jade is wholly or partly be dyed green or purple, however, and the color of the "C" jade becomes pale and fade.
"B" Jade
The treatment process of the "B" jade consists of removing the inclusions and impurities near the surface by discoloration or by chemical means, leaving all the green and white material. Polymer resin, a chemical that solidifies into an almost colorless, transparent, and then injected into the stone to fill the extra space and increase transparency. Since the structural integrity of jade damaged during the process, failures will occur very easily. If dye is injected into the treatment process can be categorized as "B + C" jade.
Natural Jade
"A" Jade
Jade "A" jade is natural and untreated. Chow Sang Sang processes do not condone treatment, so that only carry "A" jade.
