Is full green jadeite definitely valuable? Don’t buy this kind of “full green jadeite”!

In the jade market where green is the most important color, full green jade has been sought after by countless players. It seems that when full green jade is mentioned, people think of its high price and believe that full green jade is high-quality jade. But not all full green jadeite is priceless , because the value of jadeite is related not only to its color, but also to its water quality. No matter how green the color is, if the water quality is low, the value will not be too high. Therefore, when buying jadeite, you must not just look at the color!

Full green but worthless jade

Iron Dragon

Tielongsheng, produced in the Longken mining area in Myanmar, is a new variety of jade that was discovered in the 1990s. It means "full green stone" in Burmese. Because the mines where it is produced are distributed in strips and surround like a dragon, it is also called "Tianlongsheng". Tielongsheng is favored because of its bright green color and can be made into full-green ornaments, but it is limited by its overall poor transparency and coarse texture .

Because the value of iron dragon is generally not high, some merchants use it to impersonate high-end jadeite full of green to make huge profits, so be extra careful!

Dry green

Ganqing, as the name suggests, refers to a kind of jade that can be seen on the market, which looks very dry, has very little water, but is almost full green.

The green color of dry green jadeite is often black, and granular or columnar grains can be observed with the naked eye. The color is often uneven. Therefore, Ganqing is called a "poor quality" product, which means that although Ganqing jade has a deep green color, its quality is poor.

Do you dare to buy the full green jadeite that will break at the slightest touch?

Thin water material

Thin water material, also known as Guangpian, refers to thin flake jade, which was once popular in southern my country, especially in Guangdong. Guangpian is actually a production process , that is, when processing jadeite with poor transparency and dark green color, the relationship between thickness, color and transparency is cleverly applied to process the jadeite into thin slices of only 1.5mm-3mm (in most cases). Because of its thinness, Guangpian jade is also relatively fragile.

Guangpian jade often uses Ganqing and Tielongsheng as raw materials for processing. This is because Ganqing and Tielongsheng jade are usually full green, but their biggest flaw is "short water" (poor transparency). After processing them into Guangpian, not only does the jade look more transparent, but the saturation of green is also improved. Merchants usually use a backing setting to protect the main stone and make the jade appear more moist.

Guangpian jade has no collection value and its price will not be very high. Be wary of unscrupulous merchants who try to deceive you by exaggerating it as top-grade jade!

Core material

Boshui jade is thin enough, but there is a kind of jade inlay that is even thinner than it, and that is - the core material! The core material is also called bottom-dug material or punch-head material, while Cantonese people like to call it "eggshell".

The jade used for core-cutting is mostly worse than the thin water material! It has a coarse grain and no head , so it needs to be sanded thinner. Thin water materials are usually polished to a uniform thickness, but core materials are "thicker at the edges and extremely thin in the middle" . The thickness in the middle of some jade is even less than 1mm.

In fact, this kind of bottom-dig goods are made by processing and inlaying jadeite, and then fraudulently selling them by taking advantage of the visual effect of the finished product. Be careful!

Yongchu Material

Yongchu material is not jade in the strict sense. Most of this material is produced in Guatemala, on the edge of jade. It is mostly blue-green in color, with insufficient density and black spots .

In order to show the water and color, some unscrupulous merchants can only dig it into a thin skin, which will also make its black spots more obvious. Moreover, Yongchu material has an obvious defect - it is easy to change color!

Where did the counterfeit come from?

Australian Jade

Australian jade is also called South Sea jade. Although the word "jade" is in its name, it has nothing to do with jade. It is actually a green variety of chalcedony , colored by nickel. Its famous production area is Australia, where it is often produced in irregular plates and blocks. Its color is uniform and bright, and it is often used to impersonate full green jadeite. It is also quite deceptive, especially jadeite ring faces and Australian jade ring faces, which are very difficult to distinguish.

Distinguishing features

① Color: The green color of green jadeite is bright and translucent, with changes in color veins and color roots, and you can see "fly wings", while green chalcedony does not have these characteristics, and the green color is uniform, and the tone looks plastic.

②Luster: Although both have glass luster, the luster of jadeite is fresher and more transparent than chalcedony.

③Weigh the weight and listen to the sound: The density of jadeite is greater than that of chalcedony. When you weigh jadeite in your hand, you will feel a pressure. If you gently collide two chalcedony pieces against each other, they will make a dull sound, while if you gently collide two jadeite pieces against each other, they will make a clear and long sound.

Malay Jade

Malay jade, also known as Malaysian jade, is a man-made imitation jade product . Its main mineral is quartz. It is made of pure quartz or quartz crystal melted with colorant added. Although Malay jade is called jade, it looks very similar to full green jadeite, with bright colors and very attractive, but it is not natural jade.

Distinguishing features

① Zoom in and observe: There are obvious "fly wings" on the surface of jadeite, but Malayan jade does not. Moreover, the color of natural jade is usually formed by points or lines (also known as "color roots") that gradually diffuse outward. The color roots are irregular in shape and are naturally formed and cannot be imitated. However, when Malaysian jade is viewed against the light, it appears as a grid of regular green lines.

② Weigh the weight: Put the Malay jade and jadeite together and weigh them with your hand. You will find that the jadeite is heavier than the Malay jade and feels a certain amount of pressure.

Green Glass

The glass used to impersonate green jadeite is different from the common glass we see. It is an artificial glass similar to colored glaze. Green organic dye is added to the molten silica and then cooled to allow the silica to crystallize into tiny quartz crystals and slightly larger phenocrysts that are oriented and distributed in a fibrous and floc-like manner. From the appearance and internal structure, it is enough to impersonate jadeite.

Distinguishing features

① Magnify and observe: The interior of glass products has no structure. If you observe with a magnifying glass, you will see tiny bubbles and the color is not as natural as jadeite.

② Weigh the weight: The biggest difference between glass imitations and jade is that the density of glass is relatively small, so for jade of the same volume, glass imitations are much lighter than natural jade.

In addition, many merchants will artificially dye colorless or light-colored jade into green to imitate better quality full green jade. However, in larger cracks of dyed jadeite, precipitation or aggregation of dye can be seen, which may even be harmful to health. Therefore, you must be cautious when purchasing jadeite!

Although full green jade is precious, you should never just look at the color without considering the quality of the jade. You should also learn to distinguish it to avoid being deceived by counterfeit products.
