How much can this jade be worth?

This handmade material looks like Xiuyu jade, and its value is around 200 yuan. . .

Xiuyan jade is not a single jade species because of its complex material composition, different physical properties and arts and crafts characteristics. According to the different mineral compositions, xiuyan jade can be divided into three types: serpentine jade, tremolite jade, serpentine jade and tremolite jade mixture, of which serpentine jade is the main one.

The colors of xiuyan jade are dark green, green, light green, yellowish green, grayish green, tan, brown, dark red, sallow, white, yellowish white, greenish white and grayish black. The existence of such rich colors often makes xiuyan jade have extremely beautiful "clever colors". The depth of color is related to the iron content. When there is iron, the color is generally dark, and vice versa. Jade also has a strong waxy luster, glass luster, and some show oily luster; Slightly transparent to translucent, a few display. Its transparency is related to mineral composition and chemical composition. When xiuyan jade is composed entirely of serpentine, the transparency is high. If the impurity content reaches 5%~ 10%, the transparency is poor. When the iron and magnesium content in xiuyan jade is high, the transparency is often poor; On the contrary, transparency will increase.

The imitations of Yixiuyu mainly include glass, chalcedony, marble and dushan jade. ?

4. dushan jade: It is produced in Dushan in the northeast of Nanyang City, Henan Province, hence its name. Because of its different mineral composition and content, it can form white, green, yellow, purple, mottled and other colors, which is richer than Xiuyu. The color of dushan jade is often dark green to black, distributed in blocks, and its hardness is greater than that of Xiuyu. Generally, it will be carved into plates, bowls, animals, figures and other ornaments.
