Can any of the seniors tell me some ordinary ways to distinguish between real and fake jade?

There is a simple and easy way to use it, which is to take a strand of hair, wrap it tightly around the jade, and burn it with fire, if the hair strand is intact, it is true. If the hair is broken, it is fake.

It's true, I tried!

The easy way to do this is:

One is to look at the color. Color is the most important factor in evaluating the quality of jade. The jade with a uniform, yang, dense and positive color is the top grade.

"Uniform" means uniform; "Yang" refers to the bright color, giving people a cheerful and non-depressed feeling; "Thick" means that the color is darker; "Positive" means that there are no other variegated colors mixed together.

The second is to look at the texture. Jade is a polycrystalline mineral formed by silicates at high temperatures and pressures, and the size of the constituent crystals will directly affect the smoothness, transparency and hue after grinding. Therefore, the finer the polycrystalline structure, the better the texture of the jade.

The third is to look at transparency. Transparency is a physical phenomenon that complements texture. The finer the texture, the higher the transparency. If jade is as transparent as glass, the fineness of the crystals inside it allows the light to penetrate without being blocked.

The fourth is to look at the acquired processing. When jade is mined, it is just like ore, and the colored parts of the stone must be carefully cut into different ornament shapes by experienced professional craftsmen, then processed, polished, carved, polished and waxed before it can reach the market**. Those that have not been bleached, faded, or dyed at all during processing are rated "A" and have the highest value; The bleached and faded ones are rated "B", followed by the value; The dyed "C" grade is of lower value.

Excellent acquired processing can make jade icing on the cake and multiply its value.

Five look at the cracks. Cracks on jade can be caused during mining or processing. Once you have a crack, no matter how good its color, texture and transparency, it will affect its value.

Sometimes the crack is not noticeable on its surface, but it can be seen when you look closely in the sun. Especially for jade that has been bleached, faded or dyed, cracks are common.

While identifying the quality of jade, it is also necessary to prevent artificial imitation jade from being fake and real. Artificial imitation jade is made of dyeing glass, plastic and other materials. Most of the glass imitation jade contains bubbles, the color is bright, the green has a strong brightness, and the color is different from the real jade.

Plastic imitation jade is lighter than real jade, with very poor transparency and dull tone, which is far from real jade.

The following is an introduction to the advantages and disadvantages of jade, and the method of distinguishing between true and false

Water identification method A drop of water is dropped on the jade, such as a dewdrop, the real jade that does not disperse for a long time; The droplets disappear quickly are counterfeit goods.

Hand touch method If the real jade is touched by hand, there is a feeling of cold lubrication.

Inspection method Orient the jade to the light, such as sunlight and light, if the color is clear and the green color is evenly distributed, it is the real jade.

Tongue licking method The tip of the tongue licks the real jade, which has an astringent feeling; Fake jade, on the other hand, has no astringent feeling.

Magnifying glass** Put the purchased jade under the magnifying glass**, mainly whether there are cracks, those without cracks are high-quality jade, and those with cracks are secondary. Even if it is a real jade, the value of the cracks is greatly reduced, and the more cracks and the more obvious the value, the lower the value. Good luck, good fortune, good luck!

In fact, the jade on the market is real, there is no difference between true and false, or even more than a dozen yuan a piece, but jade is graded, the simplest is to look at its transmittance, good jade has relatively high transparency, and there are few impurities.

Jadeite jade is also known as Burmese jade. It was popular in China at the end of the Qing Dynasty and the beginning of the Republic of China. Because of the high hardness, good texture, strong toughness, clean and bright ground of Burmese jadeite jade, and good jadeite color is bright and peaceful, it has high value preservation and collection value, so it is called "the king of jade".

It is loved by many people who love jade and wear jade. How to choose the best Burmese jadeite jade, there is a lot of knowledge.

In terms of mineral reserves and mining volume in Myanmar, good jadeite is limited. At present, the types of Burmese jade that are popular in the market are divided according to the grade of authenticity and falsehood. There are four main categories.

A goods, goods are both natural textures and natural colors. Among them, the varieties of seedling green, cabbage green, fei color or violet flowers are more common, and the texture is delicate, the color is soft, and the stone pattern is obvious when observed by the naked eye under the light; Slight impact, crisp and pleasant sound; There is a feeling of heaviness in the hand, which is clearly different from the rest of the stone.

B goods, is to soak the jadeite with black spots, corrode, remove impurities to increase transparency, and then use high pressure to inject epoxy resin or alternative fillers into the micro-cracks caused by corrosion with strong acid. B goods at first glance the color is good, carefully observed, the color is in a daze, under the lamp observation, the color transparency is weakened. Within two years, it will lose its luster, be full of cracks, and become ugly.

Slight impact, muffled sound, no crisp sound of a cargo.

C goods are completely hand-colored. The color is not correct, look closely under the lamp, the color is filled in the cracks of the mineral, and it is distributed in a network shape, and there are no color roots. Observed with a Charles color filter, green turns red or colorless. Wipe with a strong fader to remove or turn brown on the surface.

D goods Counterfeit jadeite jewelry is divided into jade, green glass, and green plastic. The jadeite masquerading as jade has low hardness, low density and weak luster. Most of the alternatives made of green glass and green plastic are unsightly in color and have a weak luster.

The relative density is very light, the hardness is low, and there is no cooling feeling.

Most of the jadeite B goods are pickled, so the internal structure is destroyed, therefore, it must be filled with epoxy resin, so the luster of the B goods jadeite is poor, showing a waxy luster, and the reflective surface will see many acid corrosion channels like sieve eyes, which can be distinguished from A goods, because the reflective surface of A goods is extremely smooth!

In addition, the green color of the B cargo has a yellow tinge, and the color roots are divergent.

C goods are better to identify, just remember"Color is born from cracks"The characteristics of this sentence C goods, C goods have nothing to hide!

As for the difference between jadeite and other types of jade, just remember that the common jadeite on the market has jadeite and feels heavy, and it's OK!

How to identify jade:

1 Water Identification Method.

A drop of water is dropped on the jade, and if it is in the shape of a dewdrop, it is a real jade that does not disperse for a long time.

2 Hand touch.

If it is real jade, it will feel cold and lubricated when touched by hand.

3 Observation.

If you look at the jade against the light, the color is clear and the green color is evenly distributed.

4 Tongue tip identification.

Licking real jade on the tip of the tongue has an astringent feeling, while fake jade does not.

5.Hardness method.

The Mohs hardness of a utility knife is 5. Whether it is nephrite or jadeite, the Mohs hardness is higher than 5, so the utility knife cannot be carved.

In addition, you can also use a magnifying glass to observe, mainly to see if there are cracks, and if there are cracks, their value is greatly reduced.

There are six criteria for identifying the quality of jade, namely "color, transparency, uniformity, shape, knocking, and illumination".

1 Color jade is best in green, and the value of red and purple jade is only 1 5 of green jade. If the jade contains red, purple, green, and white colors, it is called "Fulu Shouxi"; If it contains only red, green, and white, it is "Fu Lu Shou". The color is dull and yellowish.

If it is a monochrome jade, it is better to have a uniform color.

2. Transparent and crystal clear like glass, no dirty spots, no chaff, no astringency is the top grade. Translucent and opaque jade are called intermediate jade and ordinary jade respectively. In the Qing Dynasty and before the Qing Dynasty, jade with three colors of red, green, and white was called jadeite jade.

In modern times, jadeite jade generally refers to jade that is generally transparent. At present, jadeite jade is mostly transparent and green.

3 The color of uniform jade is uniform, although it contains white and green but the color is uneven, the value is very low.

The shape of 4-shaped jade can be processed into different styles according to different aesthetic requirements, and there are no special standards. Generally speaking, the bigger the jade, the better.

5 There are often fractures and cuts in the jade, which are generally not easy to observe, if you knock it with a metal rod or gently throw the jade on the plate, you can distinguish whether the crack exists or not from the turbidity of the sound. The crisper the sound, the better.

6 There are black spots and flaws in the jade that are not easy to find with the naked eye, as long as you take a photo with a 10x magnifying glass, you can see it at a glance.

The quality of jade can be divided into 10 grades, and each grade can be subdivided into 3 grades: upper, middle and lower. Among them, white jade has the lowest value, regardless of its color and transparency.

1. Some simple ways to identify jade:

1. Water identification method, a drop of water is dropped on the jade, if it becomes a dew drop, it is a real jade that does not disperse for a long time.

2. Hand touch method, real jade is touched by hand, and there is a feeling of cold lubrication.

3. Observation method, the jade is observed against the light, and the color is clear, and the green color is evenly distributed.

4. Tip identification method, the tip of the tongue licks the real jade and has an astringent feeling, while the fake jade does not.

2. There are six criteria for identifying the quality of jade:

1. Color, green is the best jade, and the value of red and purple jade is only one-fifth of that of green jade.

2. Transparent, transparent and crystal like glass, no dirty spots, no chaff, no astringent jade is the top grade.

3 The color of uniform jade is uniform, although it contains white and green but the color is uneven, the value is very low.

The shape of 4-shaped jade can be processed into different styles according to different aesthetic requirements, and there are no special standards.

5. Knock, there are often fractures, cuts and cracks in the jade, which is generally not easy to observe, if you knock with a metal rod, or gently throw the jade on the plate, you can distinguish the existence of cracks from the voicelessness of the sound, and the crisper the sound, the better.

6. Photo, there are black spots and flaws in the jade that are not easy to find with the naked eye, which can be looked at with a magnifying glass.
