What is the difference between chalcedony and jadeite

Chalcedony and jadeite are completely different things, and the differences are: first, the main chemical component of chalcedony is silica, and the main chemical component of jadeite is sodium aluminum silicate, and the completely different chemical composition determines its completely different chemical and physical properties, such as jadeite is denser, more pressing, and more heavy;The internal structure of jadeite can be seen when zoomed in, but the "emeraldness" of fly wings can be seen, while chalcedony cannot be seenJadeite has a typical vitreous luster, while chalcedony has a softer luster;And so on;

Second, chalcedony is formed in a low-temperature and low-pressure environment, and jadeite is formed in a high-pressure and low-pressure environment, so the origin of jadeite is unique, and the origin of chalcedony is all over the world, and the value of chalcedony is relatively low, and jadeite is much more precious

Third, chalcedony is expensive in rare colors such as red and blue, and materials with unique characteristics such as aquatic weed chalcedony, water bile chalcedony, geode chalcedony and other strange stones are expensive, while jadeite is expensive in colors such as yang green and violet, and the only material quality is judged by a kind of water color, and the concept of jadeite strange stone is not too emphasized.

In short, chalcedony and jadeite are two completely different jade products, chalcedony is more common, cheaper, and the collection value of special varieties is relatively high;Jadeite is rarer and more expensive, and most of the good quality materials are more valuable for collecting.

Chalcedony, also known as "chalcedony", chalcedony is actually a kind of quartz, the collective name of the cryptocrystalline body of SiO2, which is a variant of quartz (cryptocrystalline). It is produced in the form of milk or stalactite, often kidney-shaped, stalactite-like, grape-like, etc., with a waxy light. Chalcedony forms at low and low pressures and occurs in cavities, hydrothermal veins, thermal sediments, clastic sediments, and weathered crusts in ejectitive rocks.

Its physical properties are the same as those of quartz. Chalcedony is used as a gemstone and is mainly used as a material for jewelry and arts and crafts. Chalcedony is the same mineral as the well-known agate.

Aphictic quartz with a band-like structure is agate, and cryptocrystalline quartz without band-like structure and uniform color is chalcedony.

Chalcedony: cryptocrystalline quartz jade. It can contain fine particles of Fe, Al, Ca, Ti, Mn, V and other trace elements or other minerals.

Ultramicroscopic cryptocrystalline aggregates, mostly produced in lumps. 2. Jadeite: The king of jadeite.

The chemical composition of the main mineral jadeite is NZALS2O6, which can contain Cr, Fe, Ca, Mg, Mn, V, Ti, and S

1. Density:

The density of chalcedony and jadeite is different, chalcedony has a small density and light weight, and there is a feeling of lightness and fluttering in the hand. Jadeite is dense and heavy, and it will produce a noticeable sense of heaviness when held in the hand.

Second, the luster:

The luster of chalcedony and jadeite is different, the surface of chalcedony is waxy, and it looks a little dull and dull. The surface of jadeite is oily luster or vitreous luster, with a high refractive index, and it looks moist and translucent.

3. Ingredients:

The composition of chalcedony and jadeite is different, chalcedony is a kind of quartz, which is a variant of crystalline, often kidney-shaped, stalactite-like, grape-shaped, etc. Jadeite is mainly composed of jadeite, sodium chrome pyroxene, and omphacite, which also contains hornblende, feldspar and other components.

Fourth, value:

Compared with jadeite, the value of chalcedony is much lower, why, the output of chalcedony is described in two words is enough, and jadeite is just the opposite, high-quality jadeite has the characteristics of beauty and less, and the storage is limited, and the scarcity is expensive.

There is a jargon called "a two-color three-process, bracelet to see the species, pendant to see the color", it can be seen that the species, color, and process are the three most basic elements of choosing jadeite, followed by the size and weight, uniformity, clarity, willow crack and aesthetics.

1. Look at the planting water.

The image of "planting a good shade of three ugliness" illustrates the importance of jadeite species.

The water head, or transparency, refers to the ability of the jadeite to transmit visible light. There is a saying: "The bracelet looks at the seed, and the pendant looks at the color". It can be seen that the importance of the jade bracelet water head. A good bracelet with a good head can make a woman look more youthful and energetic.

The grade of the species from high to bottom is: Laokeng glass species, water species, ice species, ice glutinous species, glutinous species, and other species, and the other species mainly depend on the color.

2. Distinguish colors.

There are many colors of jadeite, but the best jadeite is generally yang green. However, green means very different things to women of different ages, figures, and temperaments. When purchasing, you should choose according to your own preferences.

It is best for young women to choose bracelets with bright colors and good water heads, which look young and energetic Older women should choose bracelets with a slightly darker color to look noble and solemn.

The color grades from high to low are: green (imperial green, positive green, apple green), red, yellow, purple.

3. Look at the process:

There is a saying that "half of the material and half of the work", that is, the value of a good work is half of the value of the material and the work; The quality of the craft and the symbolic meaning have an impact on the **.

Chalcedony, also known as chalcedony, is a substance formed by quartz in a low-temperature and low-pressure environment, and the main component is silica. The main chemical component of jadeite is sodium aluminum silicate. Chalcedony is formed in a low-temperature and low-pressure environment, and jadeite is formed in a high-pressure and low-temperature environment such as a wild environment.

Chalcedony is produced in the form of milk or stalactite, often kidney-shaped, stalactite-like, grape-like, etc., with a waxy luster.

Jadeite, also known as jadeite jade, jadeite, Burmese jade, is a type of jade, the correct definition of jadeite is a fibrous aggregate composed of pyroxene minerals dominated by jadeite minerals.

Jadeite is a jade-grade stone polycrystalline aggregate formed under geological action, mainly composed of jadeite or jadeite and sodium and alda-lime pyroxene, which can contain hornblende, feldspar, chromite, limonite and so on.

1. The luster is differentThe luster of jadeite is relatively fresh and translucent, the surface of chalcedony is smooth and smooth, there is no orange peel effect unique to jadeite, and there is no particle structure. In terms of internal structure, if the inside of jadeite is fibrous and it is intertwined, this is also different from chalcedony.

2. The output is differentChalcedony is produced more on earth, while jadeite and field jade are relatively scarce and higher in economic value than chalcedony. Chalcedony and Hetian jade were found and used earlier in China, probably dating back to the Neolithic Age, while jadeite was used by the ancestors later, in fact, chalcedony and chalcedony are very different.

3. The density is differentThe relative density of chrysoprase is about the same, much smaller than jadeite, but small products should not be distinguished by hand, and must be accurately determined by measuring methods. Chrysoprase has a refractive index of about the same and is smaller than jadeite. At the same time, chrysoprase lacks the characteristics of visible light absorption spectrum, and there is no absorption line of CR.

Chalcedony is similar to jadeite, jadeite is much better than chalcedony, the main differences are different specific gravity, different luster, and different structure. 1. Different specific gravity: in terms of density, the density of chalcedony is smaller than that of jadeite, so chalcedony of the same size is often lighter than jadeite.

Of course, there is a subtle difference between chalcedony and jadeite that is too small, try to use professional measuring tools to reduce errors. 2. The sound luster is different: chalcedony and jadeite have different sounds, hit chalcedony and jadeite with the same thing, the sound of chalcedony sounds muffled and the time is short, and the sound of jadeite sounds crisp and long.

The luster of jadeite is more fresh and transparent than chalcedony, with emerald and color roots, and chalcedony cannot see emerald and color roots. 3. The internal structure is different: the inside of jadeite is a fiber interwoven structure, while chalcedony is a granular structure, therefore, it is not easy to find similar features such as fly wings, and chalcedony is not emerald and has no crystal spots.

The main difference between jadeite and chalcedony is that the specific gravity is different, the luster is different, and the structure is different, jadeite is formed by sodium aluminum silicate, with high hardness and density, and has an obvious sense of heaviness in the hand, which looks transparent like ice, and has a strong sense of luster. The main ingredient of chalcedony is silica, which is not as permeable and color as jadeite.

1. The specific gravity is different.

Chalcedony. The main difference between chalcedony and jadeite is different from hardness, because the main component of chalcedony is silica, and jadeite is formed by sodium aluminum silicate, which is a kind of jadeite.

2. The luster is different.

Jadeite. Jadeite is a more precious jade, it is mainly glass luster or grease luster, some good quality jadeite looks transparent like ice, the texture is warm and delicate, the luster and saturation are very strong, in comparison, the luster of chalcedony is much worse, there is no jadeite oil, and the internal flaws will be more than jadeite.

3. The structure is different.

Chalcedony. At the same time, the internal structure of jadeite and chalcedony is also different, through the observation of light, you can see the fibrous intertwined structure inside the jadeite, evenly distributed, looks more transparent, there will be a soft flash, and the inside of chalcedony is a granular structure, and the visual beauty is much worse.

The difference between chalcedony and jadeite is mainly in three aspects: sound, luster, and stuffiness.

1. The difference between sounds.

The sound produced by chalcedony and jadeite is different, and when you hit chalcedony and jadeite with the same thing, the sound made by chalcedony sounds muffled, and the duration is shorter. The sound made by the jade sounds very crisp, and the time lasts for a relatively long time.

2. The difference between gloss.

Although chalcedony and jadeite are both vitreous luster, jadeite looks more translucent, while chalcedony does not have a translucent feeling, but gives people a dull feeling. Chalcedony does not have the orange peel effect of jadeite, and it also does not have the color root of jadeite, and the overall positive value of the fight cover is lower than that of jadeite.

3. The difference in structure.

When chalcedony and jadeite are placed under the light, you can see that the internal structure of chalcedony is granular, and jadeite is a structure of intertwined fibers, and compared with the two, jadeite is much better than chalcedony. The color of the chalcedony looks uniform, unlike jadeite, which has a difference in shades.
