Glittering jewelry, not only embodies the nature of nature, nature also contain the designers of rigid not 2 of originality, so has always been a good heart. But with the development of science and technology, oil painting synthetic technology constantly updated, make jewelry products and evil people mixed up a bit.
Jewelry appraisal division, into the market through the fog. And all the year round in all sorts of diamond jewelry division of luster, what is the real life?
Knowledge is a jewelry appraisal "stone"
Behind the seemingly simple jewelry appraisal industry, there are ordinary people can't do it hard, identification techniques mainly comes from the study of rock parameters. A jewelry appraisal division need to master the knowledge of rock mass, perhaps it can be described as a contemporary version of the "stone".
Huang Yidao is a young jewelry appraisal division, this big boy in August after the 90 got the GIA GG certificate. GIA (i.e., the American college of gem) has been 80 years of history, was the creator of the diamond appraisal certificate of international promotion, diamond 4 c standard are set by the agency. The GIA certificate is recognized in the international scope.
Huang Yidao in went to the United States chose the geology at the university of Alabama read undergraduate course. Then enter painting the GIA learning. He said he is a real "chi" : "in the United States to study minerals and rocks, I often go to the lab for a few days to study all kinds of stone. Each saw a new stone, will be exceptionally excited, just like many car fans to see the new roadster reaction."
Because each stone has a variety of indicators, the accumulation of knowledge is very boring. "There are thousands of kinds of minerals, and we must be at least remember hundreds of different parameters of the stone. At the time of training is very hard at the time, from 9 am until 5 PM."
Certificate of inspection requirement is extremely severe. "The last request we identified 20 stone, must for every star, custom oil painting as long as the wrong one, if not through the final examination." Huang Yidao recalled: "do you want to do really loved stone to the industry, because of its great utility. Each stone, have at least a dozen indicators, all need to remember."
Sometimes, appraisal results to "art" express
Jewelry appraiser should not only have solid knowledge reserve, also has a strong compression ability and enough confidence. Huang Yidao recently opened jewelry studio in cixi, now have helped dozens of people identified jewelry.
A what is the status of the jewelry appraiser everyday? He explain to the reporter: "first of all, I'll prepare many in early identification of the instrument, equipment such as microscope, infrared spectrometer, refractometer. Customers can take their stone to the studio, I will take more than 10 steps of appraisal, takes about 20 minutes, finally write the appraisal report."
He told the reporters to share an interesting experience, once a customer in a store bought a silver bracelet, at that time they promise is 925 silver. But after identifying found plating on the surface of the bracelet is 925 silver, it is alloy. But the customer will take the expert to store theory, finally return to success.
"Sometimes you also can only express art appraisal results. This is especially embodied in acquaintances to find my appraisal", Huang Yidao smiled and said, "once a familiar customer brought a bunch of so-called crystal bracelet, through the refractometer to test after I found the refractive index is 1.49, the category of a glass. Then I gently told her that only measured not crystal bracelet, but this work can also." , he says, despite a heart after know the material about valuations, but don't usually tell customers.
Such examples abound. "Jewelry appraiser who make jewelry industry more standardized, and reassure customers can buy the real jewelry, this is the meaning of this industry." He carefully elaborated his views of the industry.
Relative to other profession, jewelry appraisal division working time very unstable. "Most customers will often in rest time with stones to identification." He says, he often got a call from the guest requirements identified 10 o 'clock at night, some guests come from far away places.
Nevertheless, Huang Yidao says the professional let he reaped another fun. "In the process of work contact new things every day, and the design of these things is not only a unique feeling, have the considerable value." Huang Yidao said.
Sales, design jewelry appraisal can fusion.

Oil painting color painting was painted with effect of strong colors. Will the more color at the same time with the brush or palette knife painted
Oil painting color painting was painted with effect of strong colors. Will the more color at the same time with the brush or palette knife painted, with a palette knife scrape color quickly, leaving only a thin colour effect. Then, use the relative complementary color and gray on this kind of intense color. The first colour too vulgar, can cover a variety of contrasting colors (mixed) do not force to become elegant, in this way, you get the effect of harmony. Make the beginner's surprise, the most warm tonal how quickly and easily turn to cool color to move, the most intense colour can to weaken again. If work change weak omen, it has to be intense color start again from the beginning, be sure to use the most decisive strong contrast color, that is the most warm or cold tonal, then, to make its relationship harmony, not weaken its original colour effect, this is compared with larger chrominance changes connected or interval to achieve certain effects. Using the contrast color painting, painter can get special ability and painting skills quickly.
Although the impressionist shape and form characteristic of color are subject to object the overall moment of feeling, but today's artists use contrast color, from a single strong colors began to paint. A painter, for example, attracted by a bright blue material, comparison and then look for it, and according to the detailed estimate of contrasting colors to draw his pictures; Careful contrast experiment was carried out at the same time also pay attention to not make the colour quality damage due to the altered too much in the picture. For painters put some colored pieces of paper or other material temporarily in some parts of the painting, to ponder what he considered a colour effect. In this way, the painter could use green instead of red, etc., to verify its effect, and does not damage the picture. In contrast color painting techniques, "Valeurs" gorgeous matchless color changes, plays an important role. By the monotonous and vulgar contrasting colors for the overall harmony of painting development, its effect is quite subtle. For each color position can be one by one according to its shade and the overall need to carefully consider, in this way, the picture becomes a continuum. Through the contrast of color changes in temperature changes can obtain the best effect, like the warmer in color red cheeks and bright contrast of cold red lips.
It goes without saying that any oil painting reproductions artist is sensitive to colour know how to arrange all the colors, so that they can blend into the mass-tone attune.
Today, many painters want to pursue a kind of flat like murals painted bright light effect, they deliberately painting in this way. To seek a kind of extensive flat with overall color effects, and to avoid some of the bright and dark locally. Chalk on a base of light color, such as cotton base, commonly used ochre color, to contrast color illustration provides conditions. With little change of color painting in general terms, such as possible within a day or two to finish still damp.
Liquidity great toning fluid, such as containing a small amount of poppy seed oil of turpentine, and refined petroleum products, pure p-xylene, decalin, and other essential oils are used by artists, so the painter using paint almost like watercolours. Obviously, adopts the contrast color painting when using color mixing liquid must be very moderate, these color mixing liquid will have strong dilution effect on the pigment. Many people still use such a skill, with the palette knife scrape off thick coating of paint, so as to draw on this flat and thin color new rich hues.
Undesirable tonal also can use a palette knife oil painting to remove, but do not use turpentine erase, because it can make the color clear of injury, the thin layer will produce crack.
In addition, there is a kind of practice, is not desirable tone with a palette knife scrape, thin layer of the tu yi on without color mixing liquid of vera's white paint. Eggs temple vera's white paint or casein white paint used for this is the best, it can prevent the color of the cover by background "upset" or being "overwhelmed", and to prevent losing its clear and bright effect. In pella pigment can then paint in oils, but had better not turpentine, use only pure oil paints. Can also be used in a similar way the Weimar (Weimar) "milk" a FIG tree.
Clearly presented here is only a general concept, and every artist has his own unique way. This will depend on what the artist hopes to achieve.
