cape verde jewelry “Cross Manipulation” for Evaluating Emerald Green

Đăng trên qua Kingjy

Because the name of emerald green is too complicated and numerous, the jewellery trade circles often use the 10 words “dense, yang, pretty, righteous, harmonious, light, yin, old, evil, flower” to evaluate it, which can be called “cross formula” .

“Dense” refers to the color dark green without black. On the contrary, nó là “light”, which means light green and weak.

“Yang” refers to bright and bright colors. The opposite is “yin”, which means the green is dim and stagnant. Even if the sun green is lighter, it is fresh and lovely. Even if the shade is deep, it is not welcome.

“Qiao” means that green looks beautiful and crystal clear. On the contrary, nó là “old”, đó là, the green appears dull and dull.

“Positive” refers to the bright and pure green. On the contrary, the yellow, cyan, màu xanh da trời, gray, black and other colors in green are all “evil colors”, and the value of evil colors is significantly reduced. Pay special attention to the differences between the subtle colors.

“Harmony” refers to the meaning of green uniformity and no floweriness. Ví dụ, the green color is in the form of strands or scattered points, scattered pieces are “Hoa”, which will affect the value of jade materials or jade articles to varying degrees.

Evaluating the value of jadeite should start from the following 8 aspects: the deviation and righteousness of the emerald green; ② the uniformity of the green shade; ③ the green shape; ④ the green head; ⑤ the impurity and cleanliness in the green; ⑦New and old species of emerald; ⑧How much is green.

Where are the best jadeites in the world? Hiện nay, 90% of the world’s jadeite is produced in Myanmar. The most famous jadeite producing areas in Myanmar are Dumao and Burmao in the Wulong River Basin in the Menggong area of ​​Myitkyina in the north. The production area has a radius of about 13km and is only 150km away from the border of Yunnan, Trung Quốc.

What is the “greenness” của Jadeite?

Các “emerald nature” of jadeite is the flake-like flash of the crystal and cleavage surfaces of the minerals that make up the jadeite. Emerald is a unique feature of jadeite, which is called “fly wing” hoặc “sand star” in gem circles. Other green rocks do not have emerald, so it is an important symbol to identify jade. Tuy nhiên, “Ngọc lục bảo” is not visible in all jadeites, because some high-quality jadeites (such as old pit glass or ice Species) crystal grains are so fine that the crystal faces and cleavage faces of it are invisible to the naked eye. On the contrary, it is easy to see the phenomenon of “fly wings” in some jadeite jade with coarser and translucent crystal grains.
