What's the difference between jadeite and jadeite? Many people don't understand the concepts of "jade" and "jade" and mistake "jade" for "jade". For example, they want to buy a jade bracelet, but they say they want to buy it. Or mistakenly understand "jade" as a specific kind of jade, you will inexplicably ask: which is better, jade or jade?
First, what is "jade"
There is such a description in China's ancient book Shuo Wen Jie Zi: "Jade is the beauty of stone", that is to say, beautiful stones can generally be called jade. According to the understanding of jewelry discipline and oriental traditional literature, "jade" is broad, including Hetian jade, jadeite, jadeite, dushan jade, agate, turquoise, Yingshi, Shoushan stone and bloodstone.
In the folk or jade industry, "jade" can also be narrowly divided into nephrite and jadeite. Nephrite (hardness: 6.0~6.5) mainly refers to jade such as Hetian jade and Kunlun jade, while jadeite (hardness: 6.5~7) refers to jadeite or jadeite rock.
In a certain jade industry, merchants will also refer to a specific jade as "jade", for example, jade is referred to as "jade" in the jade industry, or Hetian jade will also be referred to as "jade" in the Hetian jade industry.
Second, what is "jade"
Jadeite is a specific variety among many jadeites, and it is a mineral aggregate mainly composed of jadeite.

There are some differences in understanding the so-called jadeite from the perspective of petrology and commerce. From the perspective of petrology, jadeite is a kind of rock, because it is composed of various minerals mentioned above, which can be understood as a kind of jadeite rock. When the content of omphacite is high, it can also be understood as a pyroxene.
In business, jadeite refers to jadeite and pyroxene with craft value and commercial value, reaching the gem level. The name of jade comes from the animal jade bird, and red or yellow means "flying"; Green is "green", and emerald with good water and rich green is "high green".
Third, the concept difference between jadeite and jade
It can be said that jade is indeed jade, but jade is not necessarily jade. What needs special attention is that in the jade industry chain, operators often refer to "jade" as "jade", such as buying and selling jade, doing jade business, Burmese jade, jade bracelets and so on. Jade merchants got the message. In their minds, "jade" equals "jade".
Jade is the king of jade and the gem-grade jade with the highest international recognition. It has many incomparable characteristics and advantages compared with other jade varieties. Specifically, jadeite has six remarkable characteristics: rich color, stable physical properties, strong luster, high refractive index, heavy specific gravity and high hardness. In addition, gem-grade jadeite is only produced in a specific vein in Myanmar, and the uniqueness of the place of origin also determines its noble quality-"rare things are precious."
Fourth, the price difference between jade and jade.
On the whole, the price of jadeite is the highest among all jadeites. Sometimes a glass bracelet filled with green jade can reach nearly 10 million yuan, and sometimes the jade necklace even reaches 100 million yuan.

The second highest overall price is Hetian jade. In addition to the general quality of hetian jade, the price of high-quality hetian jade can also be comparable to that of upper-middle grade jade. Hetian jade is suitable for making jade bracelets because of its small size, so the price of a real suet jade and Hetian jade bracelet is close to one million yuan.
Of course, not all jadeites are the most expensive. Some jadeites with poor quality are also very cheap, and some are only tens of yuan, which is lower than the average grade agate. Among all kinds of jade, it is possible that the price of a low-grade jade will be higher than that of other high-grade jade, so the real price needs to be compared with the concrete object in order to obtain an accurate comparison.
5. Is jade better or jade better?
Unless "jade" is understood as a specific jade, the so-called "jade" refers to all kinds of jade. If "jade" refers to all kinds of jade, then jade is not as good as "jade" at this time, which shows that this is a wrong view formed on the premise of misunderstanding "jade"
When judging the quality of jade, it is generally based on quality and personal preference.
The quality of jade must be related to the physical and chemical properties of specific jade. The quality of jade is reflected in its value or price in the market. From the market point of view, it must be a specific type and a specific jade ornament with high price or value.

In addition, personal preference is also an important basis to measure whether jade is good or jade is good. For example, some people like the masculinity and rigidity of jade, while others like the tenderness and delicacy of Hetian jade.
Sixth, the difference between ordinary jade and jadeite.
Note: All the following methods to distinguish jadeite from jadeite are for reference only and cannot be completely distinguished. It is necessary to determine which kind of jade can be tested by a formal jewelry appraisal agency.
1, the difference between jadeite and nephrite
Emerald is also called "jadeite", but the explanations of "nephrite" and "jadeite" in many other places are not accurate enough. In fact, "nephrite" and "emerald" were used by predecessors. This is just a habitual name. It is not that nephrite is easily broken, and jadeite is firm and not fragile.
Because the hardness of nephrite is 6.0~6.5, and the hardness of jadeite (jadeite) is 6.5~7, both of them have the same structure, which is the densest and most stable structure. Nephrite can be divided into white jade, sapphire, jasper, jet, topaz and sugar jade by color.

(1) luster is one of the biggest differences between jadeite and nephrite. Anyone with a little experience can judge nephrite and jadeite by reflected light. The surface of nephrite presents a greasy luster, which is inconsistent in strength and soft and moist, so people understand it as moist jade. The reflective luster of jadeite presents a hard glass luster, revealing a cold chill, so it is called cold water jade.
(2) Physical properties: the hardness (6.5), specific gravity (2.90) and refractive index (1.62) of nephrite are lower than those of jadeite (7/3.33/ 1.66).
2. The difference between jade and Ma Laiyu.
In fact, the so-called Ma Laiyu is not natural untreated jade, but artificially dyed quartzite. Initially, those mercenary businessmen gave this dyed quartzite a name that had deceived China people for many years: "Ma Laiyu".
The method of identifying Ma Laiyu is simple:
(1) color. The color of Ma Laiyu is mostly green, and its biggest feature is that under the light observation, the green inside is like a fishing net, and the green is regularly arranged into small particles like small fish eggs. Under normal naked eye observation, the color of Malaysian jade is brighter than that of high-quality green jade, and the green distribution is very uniform. As shown in the following figure: (The color of jadeite will not have such a shape distribution).

(2) concave arc surface. Ma Laiyu's torus bottom is easy to show a concave arc surface, but jadeite will not have the same phenomenon.
(3) specific gravity. The specific gravity and refractive index of Malaysian jade are lower than those of jadeite, so a slightly experienced person can tell jadeite from Ma Laiyu by weighing it with his hands or looking at the reflection.
3. The difference between jadeite and Australian jade (chrysotile)
Australian jade is chalcedony produced in Australia, also known as Nanyang jade. Its color is somewhat similar to jade, but its color characteristics and color distribution are essentially different from jade:
chrysoprase
(1) minerals. Australian jade is mainly composed of aphanitic silica, which is mineralogically called chalcedony. The main component of jadeite is columnar or fibrous jadeite, and the unique "emerald" can be seen under the magnifying glass.
(2) color. Australian jadeite is either uniform in color or has obvious parallel ribbons, mostly apple green and looks like plastic. The color and hue of jadeite will change deeply. Except for some jadeite with uniform color, most of them can see the "color root" of jadeite.
(3) The hardness of jadeite is lower than that of Australian jade, but its specific gravity and refractive index are higher than that of Australian jade.
4. The difference between water foam (albite jade) and jadeite.
Water foam is a mineral combination mainly composed of albite. Some water foams are similar to jadeite, such as transparent or translucent water foams are similar to some jadeite, but they are quite different in essence.
(1) component. The main mineral of water foam is albite, and its mineral crystals are granular. The fracture structure is similar to that of ordinary quartzite, and it will not show the unique "emerald".
(2) luster. Due to the density difference and its own crystal structure, the reflective luster of water foam is weak, and the glass luster has some colloidal luster flavor. And jadeite is glass luster.
(3) color. Blisters also have various colors, but the hue of the color is relatively light, which can't reach the best color of jadeite.
(4) hardness. The hardness of water foam is lower than that of jadeite, so it is often scratched by other objects.
5. The difference between jade and jade.
Xiuyan jade is a kind of local jade, named after it is produced in Xiuyan Manchu Autonomous County, Anshan City, Liaoning Province, and is one of the four famous jade in China.

(1) hardness test. The hardness of jadeite is obviously lower than jadeite. Carving the jade surface with sharp objects can produce scratches, but the jade will not be damaged.
(2) Look at the gloss. Jade has obvious grease luster or wax film luster, while jade has glass luster.
(3) specific gravity. Jade is the same size as jade, and jade is slightly lighter than jade.
