How to evaluate the quality of agate

There are many types of agate, and there is a saying of "a thousand kinds of agate." Agate is a cryptocrystalline jadeite of silica. Our common agate is red onyx, blue agate, green agate, sardonyx, black flower agate, violet agate, algae, agate, white agate, agate and so on.

When evaluating agate raw materials and their products, the key lies in whether the colors are positive and whether the use of QiaoColor makes sense. In the color, red, silk red, red, orange red for the top grade, dark red, purple for the next color, some material in the block is dark red, but make the product is bright red, we must seriously identify. The green onion core green and brilliant green are the top grades, and the dark green is the second. The sapphire blue and violet blue in the blue agate are the top grades and the blue is the top grade.

In the evaluation of raw materials, there are more than two kinds of colors in the agate as fine materials, and some agate has more than five kinds of colors or several different colors, which are good material for doing beautiful color design.

At present, the largest agate in China is agate produced in Brazil, ranging from 15 yuan to 30 yuan per kilogram. Domestic agate is mainly used in Liaoning, Yunnan, and other places. The value is slightly higher than that of Brazil, because the artificial processing of agate is perfect, the market Most of the agate products that we saw were heat-treated and colored, and most of the natural colors were not ideal.

Qiao color works should be clearly separated, mixed with color avoid. The color distribution on the agate is ever-changing, there is a contrast between color and color, and the use of color must pay attention to the contrast, and the wonderful Qiao color works not only distinguish colors, but also contrast strongly, and more importantly, based on the material forming basis. On top of that, color shaping, making the works depend on each other's form, and it's wonderful to be in tune with the natural form.

There are many agate's wonderful Qiao works, such as agate chicks, agate shrimp plate, agate crab basket, agate dragon plate, agate five goose, etc., are the best in agate color.

When assessing agate works, the first thing to distinguish is the general works. It is a better artwork, a masterpiece and a treasure. Although there is no strict boundary between the two, the value difference is very large. For example, we can use 500 yuan to buy a pretty color agate shrimp plate, and some 5,000 yuan will not be sold, the real good color Agate Shrimp plate 50,000 yuan will not sell.

In the evaluation of agate works, in addition to the use of color, color, technology, design also occupies a large proportion. Good works are well-designed, crafted, and polished.

Because agate's raw materials are not expensive, the price difference between materials and materials is also very small, the most critical is the design concept and production process.
