There is a famous saying in the jade industry, that is, "If you don't know the market, you don't play with rough stones." The main reason why raw stones are so elusive is that there are many markets. The jadeite produced in each producing area has its own characteristics in appearance, quality and color. Therefore, when purchasing raw jadeite, you must understand the origin and characteristics of the jade material.

1. Pagan Changkou

Pagan jade has long been famous for its good planting, good background and good color. It is mainly divided into mountain stone and water stone. Half-mountain and half-water stone are rare. Black black sand is the best mountain stone, followed by yellow salt sand and white salt sand. The sofa is uniform, with fine particles and strong hand feel; water stone has a thin skin, and most of them are transparent. feel.

However, regardless of the mountain rocks or water stones, there are pine flowers on the Pagan leather shell. The bottom water is mostly good, and the dry bottom wood bottom is less. There are yellow mist and white mist layers. Once there is color, the color grade is all the same. relatively high.

Pakant emerald is in the middle and upper green. Old Pakant stone is mostly black sand-skin, as black as lacquer. Its main features are white moss, transparent bottom, and pure green color. Once there are pine flowers, color bands, and white mist, it must be a good background.

2. Mosixisha Changkou

Moxisha Jadeite Changkou is famous for producing the best glass jade, but now the bottom layer has been dug, and most of them have black skin. It is a stone, but the glass jadeite produced from the underlying black stone is also of the highest quality.

Since most of the jadeite exported from the Mosisha Jadeite Market has a glass bottom, there are generally very few colored jadeite, but once it is colored, it is very rare and high-quality.

3. Mowanji Field Entrance

Mowanji is located on both sides of the Mowan River tributary northeast of Pagan Field Entrance. All the emerald sand deposits mined are highland gravel layers. , the highland gravel layer is cut by the river, about 100 meters deep. So the cut gravel layer profile is visible on both sides. The gravel layer is divided into two layers from top to bottom, the upper layer is red layer and yellow layer, and the lower layer is gray to black layer, semi-cemented, containing green schist and mica schist.

Emerald gravels often have wax shells. The gravels are semi-rounded to sub-angular. They are mostly black sand and have thick skins. The shells are as black as black paint and there is fog under the skin (the black ones in many markets are The leather stone has no fog and is a Xinchang stone). There are pythons with white fog and pine flowers. Generally, they are well planted and have high green. Small ones will be full of green.

4. Damakan’s rough stones are mostly famous for their half-mountain and half-water stones, followed by water stones. The skin is generally thicker and often has a honeycomb shape. The colors are brown, yellow, gray, and wax shell is rare. Almost all have a fog layer, the color level is generally higher, and the color is bluish. The main characteristics are color string skin, fog string skin, fog wrapped color, fog eating color, and the skin and flesh are difficult to distinguish.

This kind of stone with half mountain and half water has yellow shell, yellow mist and thin skin, and is highly gambleable. If the skin is thick and the fog is black, it should not be gambled. The bottom will be gray and the water will be short, the green color will tend to be bluish, and it will have no rebound power. Although the color of the water stone part can be seen, it does not enter the inside. The Damakan rough stone part has loose flowers inside, and the colors are generally not connected.

5. Huika Field

Huika rough stone field is famous for its wax skin. The yield rate of old Huika jade rough stones is quite high. If they are colored, they are usually To achieve the color of the ring surface, most good ring surfaces will have more jams. The raw stone produced has variegated skin colors, mainly gray-green and gray-black. The transparency varies, and the water bottom is unevenly distributed. However, where there is green, the water is usually better.

There are many rough stones that are stuck and desanded. There is a light red wax shell on the skin, and the inner sand is mostly water-turned skin or chicken skin sand. On the bottom seal with short water, there is often high color green or full color green.

Nowadays, the number of jadeite rough stones produced in the market is also decreasing day by day. Most of them are white background. Due to their good completeness, they are also sought after by many jadeite lovers.

6. Mu Na Changkou

Most of the Mu Na have white skin, and some will have a little red skin. If there is white haze, the jade flesh will appear after cutting. It's definitely good. Munachang is famous for its white salt sand and arrowroot skin.

Most of the jadeite rough stones at Kinabagoguchi are clear water, blue water with a background color, and white background with floating flowers, and the cotton is rarely found. If it is excellent, It can be considered the best.

Because the raw jadeite from Mu Na Changkou is easy to dissolve, it is sought after by many stone gamblers. However, some people have difficulty in distinguishing the authenticity of its shell.

7. Houjiang Changkou

The old material at the Houjiang jade raw stone field comes from the bottom of the alluvial layer in the field area, also known as Kandi jade. The bottom of Houjiang field is generally relatively thick. It is good and has high transparency. It is common to see the green Yang Cui with good bottom water, and the green with poor bottom water is bluish.

The wax shell in the middle and upper layers is relatively complete, but the quality of the stone is not good, and the color will fade after being polished; the wax shell in the middle and lower layers is incomplete, but the quality of the stone is better, and it has "nine out of ten stones." "Water", generally the color can be increased by more than one point after grinding. This is the obvious difference between old and young seeds.

The main characteristics of Houjiang farm are that it has a thin skin with waxy shell and no fog; generally the bottom water is good, and there is more green color. It often produces full green and high emerald green, less fog and less cracks, and the color of the finished product is better. It has good processing performance and is an ideal material for making ring noodles.

8. Martha Changkou

The Martha Jade Raw Stone Changkou is located on the west slope of Longken Mountain. It is a secondary deposit developed on the residual slope.

Masha Changkou, also known as Masha Changkou, was mined after 1980. It is a new factory jade with no skin or less skin, fine flesh, spring, bean color, etc. The disadvantage is that there are many cracks. , the green is relatively light, and the water and bottom are good and bad. It is mainly used as low-end bracelet material or large-scale white goods.

9. Nanqi Changkou

Mohan Jade Factory is usually called Nanqi Chang, and the jade produced is also called Nanqi Stone. Due to the small size of the farm, the jade pieces are small, and the quantity of jade produced is also relatively small, so it is called a small farm. However, the quality of the jade is relatively good, especially the color of Nanqi jade, which is often reversible, and is the best among all the sites.

If it is the same color, the stuck stone can turn over one color, the Houjiang stone can turn over two colors, and the color of Nanqi stone can turn over three colors. This is why Nanqishi is generally favored by experts.

Nanqi jade has skin and fog. There are various colors of sand-skin shells, and they are generally relatively thin, while the fog is mostly white fog. Among them, water-turned sand jade with thin skin and thin white mist is the best. It is old and has delicate meat.

10. Geyingjiao Field

Geyingjiao materials have fewer variations, but discoloration is more common. Depending on the mineral layer, the probability of high water content is greater. Generally, between the Nuo species and Nuo Bing, more coloring materials are produced.

And for materials with lattice patterns, color gradients are more common. The outer layer has a better color, and towards the middle, color changes appear on both sides. Therefore, the bet box should be glued, the shell structure, and the sand turning effect are very important.
