What is the difference between jade and stone in composition?

Traditional Chinese Culture.

In China, jade has been endowed with high cultural value, especially the ancient literati attached great importance to jade, and there was "a humble gentleman, gentle as jade."

It is often said that jade gives people character. As for jade, in fact, the ancients first had the saying that "beautiful stone is jade", that is to say, from the perspective of culture, good-looking stones can be counted as jade. However, in modern times, jade has evolved from cultural connotation to specific chemical and physical definitions.

Therefore, jade defined by modern people through chemical analysis is directly distinguished from the content of its components.

The reason why jade is crystal clear and white is flawless has a lot to do with the mineral composition and crystalline form contained in it. Jade is broadly divided into jadeite and nephrite, jadeite is represented by jadeite, and nephrite is represented by Hetian jade. Here is a brief explanation of the difference between the composition of these two types of jade compared to ordinary stones.

Nephrite: One of the characteristics of nephrite is that it contains tremolite content, generally reaching more than 95%. Tremolite is a type of dolomite.

and quartz mixed with post-sedimentary metamorphic rocks.

The mineral crystals are arranged in a radial or columnar pattern.

The main ingredient is calcium silicate.

Magnesium iron, and according to the content of other minerals, there are different luster properties. Among them, the famous Hetian jade has the highest tremolite content.

Jadeite: Silicate composed of sodium and aluminum.

It is composed of a variety of pyroxene group elements as the main component, among which silica.

accounted for about 58% of sodium oxide.

It accounts for about 13%, and the emphasis is that its form is mostly short columnar crystals. In fact, the reasons for the formation of jade are complex, and no two pieces of jade are exactly the same. In particular, even if the composition is the same, the crystal arrangement is different, and the overall reflectivity, gloss, and transparency are different.

Suppose there is a stone whose chemical composition meets the standards of jade, but these components do not form good crystals, so it cannot be said to be a piece of jade. Therefore, the ancients said that "beautiful stone is jade" also has a certain truth, regardless of its composition, whether it is enough to meet the standard of "beauty", whether it is translucent enough, whether there is enough luster, these are the criteria for judging whether it is stone or jade. It's not just about its chemical composition.

Jade is a beautiful stone, the composition is sio2 but there is a qualitative difference, jade is usually transparent and tough, can be carved, elastic while the stone can not be carved, it has no toughness, it is easy to break when shaking and the appearance is rough.

It is said that jade is jade, jade is also a kind of stone, and the main component of jade and ordinary stones is silica, but they are different in trace elements.

1. Beautiful, the color is required to be bright and pure, transparent and flawless, shiny and brilliant, or to show special optical effects such as color change, color change, starlight or cat's eye. 2. Durable. Gemstones not only need to be beautiful, but more importantly, they must have the durability to maintain their brilliance and sparkle, they must be hard (precious stones should be above 7 on the Mohs scale), wear-resistant and have good chemical stability.

3. Rare. Gemstones are scarce, and even the most showy gemstones can suffer their commercial value if their resources are widely distributed. For example, centuries ago, when amethyst was first discovered in Europe, it was considered a precious gemstone because of its beauty and novelty, but when a large number of high-quality amethyst ores were discovered in Brazil and other places, amethyst no longer enjoyed the name of treasure.

Another example is the high-quality emerald gemstone, which costs $20,000 per carat, which is much more expensive than diamonds, which does not mean that emeralds perform better than diamonds, but because emeralds are produced less than diamonds.

Jade is also a stone, with different colors, no good or bad, depending on their aesthetics.

The nature of jade is relatively stable, while many jade-like stones will become dry and dull after a long time.

Human nanotechnology, chemical technology, can make diamonds, **, it is estimated that it will not be a problem to manufacture golden silk nanmu, ebony, and jade in the future.

Jade has translucent and translucent stones.

The rich are called jade, and the poor are called stones.

The main chemical components of jade are: silicon dioxide, aluminum oxide, sodium oxide.

Jade is rich in a variety of trace elements, such as zinc, iron, copper, manganese, magnesium, cobalt, selenium, chromium, titanium, lithium, calcium, potassium, sodium, etc. The moisture of jade can eliminate the impetuous heart, the color of jade can delight the bored heart, and the purity of jade can purify the dirty heart.

Therefore, the gentleman loves jade and hopes to find the natural aura in the jade. Jade is the beauty of stone, and the color is positive and the moisturizing quality is pure and high-grade. The same goes for gemstones.

Its value does not depend entirely on the ingredients, and the most of the jadeite white jade is worthless. Just like people, every nation produces heroes.

Formation of jade:

The conditions for the formation of jade are extremely special and complex. Most of them come from high-temperature melted magma tens of kilometers underground, which pours from the ground along the cracks to the earth's surface, where it cools down and becomes hard stone.

In this process, only certain elements slowly crystallize into hard jade or gemstones, and they are formed very far away from us.

Hello, jade is rich in a variety of trace elements, such as zinc, iron, copper, manganese, magnesium, cobalt, selenium, chromium, titanium, lithium, calcium, potassium, sodium, etc. From the perspective of Western gem culture, there are two kinds of jade: soft and hard, and the jade usually refers to nephrite.

It contains silicon dioxide (SiO2), aluminum oxide (Al2O3), sodium oxide (Na2O). The theoretical content value is as follows, silicon dioxide (SiO2); Aluminium oxide (Al2O3); Sodium oxide (Na2O). In addition, there are a small amount of amphibole minerals and albite, iron chromium and other minerals.

Hardness, specific gravity, refractive index.

The differences between stone and jade are as follows:

The difference between stone and jade is mainly reflected in the following aspects:1The composition is different.

The stone is composed of calcium carbonate and silicon dioxide. It is lumpy or oval-shaped, with rough appearance, smooth appearance, firm and hard texture. The jade is fine, hard, shiny, and slightly bright.

2.Refers to different ones. Stone refers to a small rock mass that falls off from a large rock mass when it encounters an external force.

Jade is a beautiful mineral and a type of stone. 3.The effect is not the same.

The most important use of stone is concrete. As a kind of ornament and collectible, jade is a special culture in China. Full color dual-purpose text ring + pendant stone:

Consists of calcium carbonate and silicon dioxide. It is lumpy or oval, with a rough or smooth appearance, and a firm, brittle texture.

Jade is mainly divided into jadeite and nephrite.

The three main components of jadeite are silicon dioxide (SiO2), aluminum oxide (Al2O3), and sodium oxide (Na2O), and their theoretical content values are: silicon oxide (SiO2), aluminum oxide (Al2O3), and sodium oxide (Na2O). In addition, there are a small amount of amphibole minerals and albite, iron chromium and other minerals. Hardness, specific gravity, refractive index.

The main component of nephrite is calcium magnesium iron silicateHardness: Specific gravity: refractive index:

Birefringence: Nephrite is identified as a different type of jade, occurring as fibrous amphibole crystal aggregates. Tougher than the interlocking structure of steel, it is regarded as a superior carving material, and was first used as a **, and later as an ornament.

Its color varies from iron-rich dark green nephrite to a magnesium-rich, creamy variant that may be homogeneous, spotted, or streaked.

There are a lot of jade stones on the Plaything Dezhi platform, and you can watch them.

The difference between jade and stone is different in concept, different appearance, different touch, different sound, different texture, and different identification.

1. The concept is different

Stones are large and small stones scattered on the surface of the riverbed in the rivers and mountains in nature, with various colors and different shapes; Jade is jade with certain mineral properties, which contains ore mineral rough stones, and the minerals inside determine the color of the outside of the jade. But it is worth mentioning that good strange stones have good ornamental, scientific research and collection value.

2. The appearance is different

The transparency of the stone is poor, and the whole body is dull, and the jade is different, mostly transparent or translucent, and the texture is natural.

3. The touch is different

The stone is rough and cold, the jade is warm and delicate, and the collection of domestic first-line auction houses is limited to fine products, which feels good and can slowly rise with the temperature of the human body.

4. The sound is different

The stones collide with each other to make a dull, hoarse sound; Promise not to send in will not charge any fees, no appraisal fee The whole process is open and transparent, please consult the author of this article for details. However, the sound of the jade colliding and striking is relatively crisp and pleasant, and there is a slight aftermath lingering.

5. The texture is different

Generally speaking, the texture of jade is relatively hard, because jade contains minerals and has high density, on the contrary, the stone is easy to break without this mineral, but the texture of a few good strange stones is still very good.

6. Distinguish differently

Relying on the different textures to identify, it was mentioned above that jade contains minerals and has a high density, so the hardness is much better than that of stone, and the basic standard is that the knife is carved without traces.

The differences between jade and stone are as follows:

1. First of all, the biggest difference between jade and stone is the economic value, a good jade can buy more than one million, but a few hundred stones have a big car.

2. It is different for the human body, the composition of the stone is not beneficial to the human body, but the jade is different, in the process of long-term wear, the mineral elements in it penetrate the pores and can transport substances beneficial to the human body into it, which is very helpful for beauty and detoxification.

3. Even if the stone is worn for a long time, its structure will not change, but jade is different, whether it is transparency or color and many other aspects will get better and better.

How to tell the difference between jade and stone

1. Jade is a stone that has reached a certain standard in terms of hardness, luster, and feel, and is a kind of stone. When judging whether it is jade or stone, you can use the drip method, a drop of water is dropped on the surface, the water droplets are condensed but not dispersed, like the dew on the lotus leaf is jade, the water droplets disappear quickly, and it is the stone that disappears in a blink of an eye.

2. Judge whether it is jade or stone, and you can also touch the feel. The touch is delicate, the tentacles are lubricated, and the jade is very smooth when touching, the touch is rough, the tentacles are sluggish, and the stone is obviously resisted when touching.

3. Judge whether it is jade or stone, and observe the luster. Observing in the light, the surface has a glass luster or grease luster, which looks brighter is jade, and the surface has no obvious luster, and it looks duller than stone.

4. Determine whether it is jade or stone, and test the hardness at the same time. The hardness of jade is generally relatively large, and it can not leave traces when carved with a knife, and the hardness of stone is generally lower, and it can leave traces when carved with a knife.

Different elements: jade is rich in a variety of trace elements, while stone is generally composed of calcium carbonate and silica. There are different types of content:

There are more than 10 kinds of jadeite jadeite, including Xiuyan jade, Jiuquan jade, etc., and jadeite is jadeite. There are also types of stones, such as malachite and hibiscus stone. Values are different:

The value of jade is much higher than that of ordinary stones, and the value of rarer stones is also very high. But ordinary stones are far from jade. <

1. Different elements: jade is rich in a variety of trace elements, such as zinc, iron, copper, manganese, magnesium, cobalt, selenium, chromium, titanium, lithium, calcium, potassium, sodium, etc., while stone is generally composed of calcium carbonate and silicon dioxide.

2. The types contained are different: jade is divided into nephrite jadeite, among which nephrite includes Xiuyan jade, Nanyang jade, Jiuquan jade and other more than ten kinds of nephrite, jadeite is jadeite, the color is white, purple, green. It can be called ice or green.

There are also many types of stones, such as fluorite, malachite, hibiscus stone, etc.

3. The value is different: the value of jade is much higher than the value of ordinary stones, but if it is a thinner stone, such as a stone collected by celebrities, a special stone such as meteorites, dinosaur egg fossils, etc., the value is also very high, but according to the value gap between ordinary stones and jade, there is a big difference.

The difference between stone and jade: different compositions, different types, and different values.

1. The ingredients are different

The composition of jade and stone is different, and jade is rich in a variety of trace elements and minerals, such as zinc, iron, copper, manganese, magnesium, etc. Stones are usually composed of calcium carbonate and silica, and the composition is relatively monotonous.

2. Different types

The types of jade and stone are different, jade is divided into soft and hard, nephrite jade has Hetian jade, Xiuyan jade, Nanyang jade and other types, jadeite generally refers to jadeite. Stones are mainly classified according to color and composition, such as fluorite, malachite, hibiscus stone, etc.

3. The value is different

The value of jade and stone is different, jade is formed by absorbing the essence of heaven and earth, the texture is warm and delicate, and has extremely high value. In contrast, the value of the stone is more average, and there are very few priceless stones.

Jade Identification Criteria

1. The texture of jade: refers to the fineness and warmth of jade. The division of jade quality here should be graded and evaluated according to the specific jade species, but no matter which kind of jade is inseparable from the four basic entry points of "water, permeability, oil, and moistness".

2. Hardness of jade: Hardness refers to the ability of jade to resist external forces (such as pressing, carving, and grinding). The higher the hardness, the more difficult it is to process, and the better the quality of the jade sock skin stone.

3. Toughness of jade: refers to compressive hardness, or press-in hardness, that is, absolute hardness, which refers to the ability to resist external impact force, which is also called toughness in the jade industry. The highest compressive hardness in nature is Black King Kong, which is marked at 10 degrees, followed by Hetian jade, which has a compressive hardness of 9 degrees.

4. The specific gravity of jade: refers to the density of jade, different jade has different densities, and the same kind of jade in the same volume comparison, the larger its specific gravity value, the higher the quality.

5. The color of jade: the color of the mu difference is the most intuitive visual experience of jade, and to a large extent, it is often determined by the color of a piece of jade. Green is the best jade, and the value of red and purple jade is only 1 5 of green jade.
