What is the performance of jadeite seed age, and how to look at the jadeite seed old and tender

How to distinguish between old and young jadeite, we can look at it from the following four aspects:

1.From the point of view of physics, the difference between the old and the young is the difference in hardness.

The hardness of old jadeite is higher than that of young jadeite. In life, we will find a phenomenon that the sound of hard things hitting is crisper than that of soft things, so we can distinguish between old and tender by tapping jadeite with hard objects.

2.From a visual point of view, the old jadeite polishing has a mirror effect and is very bright, and the tender jadeite polishing is not bright enough. Jadeite above the glutinous ice species can fluoresce.

This is also the difference caused by different hardness, the higher the hardness, the brighter the polish; Jadeite with low hardness is not polished bright enough, and the gloss is poor and stuffy under natural light.

If the species is very old, it can reach above the glutinous ice, and the jadeite will fluoresce after polishing.

The fluorescence phenomenon of jadeite is because the crystal arrangement of the particles is abnormally neat and orderly, resulting in the overall refractive index of the light after entering, and the jadeite below the glutinous ice species is not as neat as the crystal arrangement of the jadeite, which causes the light to enter and form particle scattering and cannot become a bright and "rigid" strong light.

Therefore, the old jadeite does not necessarily fluoresce, but the fluorescent jadeite must be very old.

3.The jade species with fine meat and good water is old.

What kind of jadeite can be called a good kind of jadeite?

The jadeite industry is recognized as the glutinous species above the good planting, so the jadeite above the waxy species has high hardness, the reason is that the crystals are closely arranged, that is, the flesh is delicate, and the water head should be sufficient at the same time (except for the ink cui and blue water, the water head of the ink cui and blue water is short, but the species is very old, and the meat is also delicate, which is due to the fact that the generation of color blocks the light source).

If the average particle size (diameter) of jadeite particles is less than one millimeter, showing a microcrystalline structure, the jadeite species are relatively old, such as ice species and glass species; If the jadeite grains are coarse like beans and show a coarse-grained structure, the jadeite species are relatively tender, and usually the jadeite species are called "bean seeds" or grades below the bean seeds.

4.Some of the jadeite species with thick flesh but good water and transparent water are also old.

As mentioned earlier, the jadeite with good meat and water is old, but there is also a special phenomenon, that is, there is a kind of bean bottom jadeite (the reason why the bottom of the bean is emphasized is because this kind of jadeite is only the base is thick, and not like the ordinary bean species), although the meat is thick, the naked eye can clearly identify the crystal, but the species is very old.

The reason for this phenomenon is that the jadeite water head is good, although the crystals are thick, but they are arranged in an orderly manner, and the crystals inside are full of water head and very transparent.

Many friends are confined to the traditional jadeite point of view, thinking that the thick jadeite will not be old, but as I said before, the old jadeite sound is crisp, if you have the opportunity to encounter this kind of thick but very transparent jadeite in the market, you may wish to try it, anyway, it has been verified, the sound is very crisp; Besides, it is said that a particularly old jadeite will fluoresce, and there are a lot of jadeite with a particularly good coarse water head and a particularly transparent jadeite, which also fluoresces after polishing, which can be seen that the hardness and rigidity of this jadeite are absolutely enough to be called old.

The performance of the old jadeite species is to glue and harden! The meat is delicate! I'll put some pictures for you to see!

<> "How to look at the old and tender jadeite.

Emerald trivia.

Vision. In addition to sending the jadeite to be tested, we can also find some differences through our own observations, such as the old jadeite after the completion of polishing the luster is stronger, there is a mirror effect, and the tender jadeite will be very smooth after polishing, but the luster is always not so strong, the older jadeite will even appear luminescent, the old jadeite is not necessarily fluorescent, but the fluorescent jadeite must be a kind of non-closed liquid ever-old, if you see the jadeite luminous, everyone hurry up, don't miss it.

The visual effect is relatively intuitive, and the luster of jadeite is not strong even if consumers without any experience can see it, so if you don't have much professional knowledge, you must carefully observe the surface of jadeite.

Texture. Generally speaking, the jadeite species with good meat and water are relatively old, in the industry, everyone generally recognizes the sedan liquid as the glutinous jadeite species, even if it is better, in general, the jadeite species with higher water will be older than the buried. The jadeite crystals with high water are arranged tightly and the flesh is more delicate than the jadeite, and the water head is also relatively sufficient, such as ice jadeite and glass jadeite, the color of ink and blue water jadeite is more special, and its texture can only be seen clearly by lighting.

Leather shells. Does it mean that the ice jadeite and glass jadeite must be very old? The species of waxy jadeite and bean jadeite must be more tender?

In fact, it is not necessarily, this is just a matter of probability, most of the jadeite with high water is older, but there are also tender. If we want to buy a piece of jadeite rough with a leather shell, how can we tell if it is old or young? First observe the fog layer of the skin shell The fog layer is relatively thin, about a finger wide or narrower, this piece of jadeite rough is likely to be older, and the fog layer is thicker, and the species is generally more tender.

Then it is necessary to observe the overall shape of the jadeite rough, if the shape of the rough stone is clear, the germplasm is generally older, and this method is generally only used for assistance, and there is a certain reference. Although the value of old jadeite is generally higher, the value of jadeite is determined by many factors, such as color, water head and carving, etc., we can't just stare at its species and ignore other aspects.

1. Old: The structure of jadeite is dense, the structure is not obvious, and the bottom is clean. Tender: The structure of jadeite is not dense enough, the structure is more obvious, and the cotton and other materials on the bottom are slightly more coarse and slippery.

2. The jadeite is old, which contains two meanings: 1. High transparency, that is, the jade body is clear. 2. Good clarity and very few impurities.

3. The seed age of a certain piece of jadeite means that its grains are fine and tightly combined, that is, the seed is fine, the germplasm is fine, that is, the texture is good and the texture is very good. The old seed is a good seed, and the old seed is a good seed.

4. What does the age of jadeite mean: The age of jadeite refers to the dense structure of jadeite, the structure is not obvious, and the bottom is clean. The relatively old one is a kind of tenderness, which means that the structure of the jade stool is not dense enough, the structure is more obvious and there are slightly more substances such as cotton on the bottom.

5. The "species" of jadeite refers to whether the texture of jadeite is delicate and the structure is compact. Jadeite is a polycrystalline composed of a variety of minerals, and the tighter the crystals, the better the water head. In other words, the more delicate the texture and the tighter the structure, the older the species.

Old: The jadeite structure is dense, the structure is not obvious, and the bottom is clean. Seed tenderness: The structure of jadeite is not dense enough, the structure is more obvious, and there are slightly more substances such as cotton on the base.

The jadeite is old, which contains two meanings: 1. High transparency, that is, the jade body is clear. 2. Good clarity and very few impurities.

The seed age of a certain piece of jadeite means that its grains are fine and combined with the tight wheel Hu stove, that is, the seed is fine, the germplasm is fine, that is, the texture is good, and the texture is very good. The old seed is a good seed, and the old seed is a good seed.

The "species" of jadeite refers to whether the texture of jadeite is delicate and the structure is tight. Jadeite is a polycrystalline made up of a variety of minerals, and the tighter the crystals, the better the water head. In other words, the more delicate the texture and the tighter the structure, the older the species.

What does the old jadeite mean: The old jadeite refers to the dense structure of the jadeite, the structure is not obvious, and the bottom is clean. The relatively old one is tender, which means that the jadeite structure is not dense enough, the structure is more obvious and there are slightly more substances such as cotton on the bottom.

Old jadeite has a high collection value in the market, and its characteristics include uniform saturation of color, high transparency, delicate texture, and unique texture level.

First, the color is uniform and saturated

Older jadeites usually have a more saturated color and are usually more uniform in color. These colors include light green, medium green, dark green, light cyan, etc., and the shade of color is usually determined by trace elements such as chromium and iron in jadeite.

Second, high transparency

Older jadeite usually shows higher transparency, and there are fewer obvious cracks and blemishes on the surface, which are all signs of good jadeite quality.

Third, the texture is delicate

Aged jadeite has a delicate texture and a silky touch, usually showing high gloss and polish, which is also one of the characteristics of high-quality jadeite.

Fourth, the texture level is unique

The texture of old jadeite is usually more complex, and many layers of texture can be seen, which form unique patterns and colors, adding a lot of artistic touch to the jadeite.

Precautions for maintaining old jadeite:

1. Avoid long-term exposure to sunlight and avoid high and low temperature environments to prevent jadeite from cracking or breaking due to temperature changes.

2. Avoid contact with chemicals, such as acids, alkalis, oils, etc., so as not to corrode and damage jadeite.

3. Avoid long-term contact with water, especially hot water, so as not to damage the texture and luster of jadeite.

4. Avoid colliding or rubbing with other hard objects to avoid scratches and damage on the surface of jadeite.

5. Do not mix jadeite with other jewelry, it is best to store it separately in a soft box or bag.

6. Clean the jadeite regularly, gently wipe it with a soft brush or soft cloth, and avoid using a brush or abrasive engraved with high hardness.

7. If there are surface cracks or flaws in the jadeite, do not repair it by yourself, and it is best to hand it over to a professional appraisal agency or restoration craftsman for processing.

To judge whether the jadeite species is old, you can start from the following four aspects:

Observation shell method: observe the thickness of the jadeite shell, the jadeite with a coarser shell has larger internal crystalline particles and relatively coarse germplasm. On the contrary, the skin shell is delicate and smooth, the internal crystalline particles are smaller, and the germplasm is more delicate.

Water splashing auxiliary method: observe the water beads in the incision part of the jadeite, if the water beads are very uniform and the beads are not condensed, it indicates that the jadeite species is older.

Observe the trachoma of jadeite: Observe the frosted surface of jadeite, if the sand grains are in an upright state, unevenly distributed, and rough and piercing, it is an old jadeite.

Look at the polished surface: Observe the polished surface of jadeite, the polished surface of the old jadeite is often very smooth, and the gloss is strong. On the contrary, the polished surface of the new jadeite is rougher, and the gloss is not strong.
