What kind of jade is aventurine jade? How to distinguish aventurine jade from A jadeite?

There are a lot of jade stones on the market that are counterfeit jade, which often makes novice friends unable to guard against them. Today, we're going to talk about aventurine jade, which is often made into beads, fake bracelets, and beads. Dongling jade, also known as aventurine jade, also known as aventurine stone, also known as sea stone or aventurine stone, is geologically known as chromium-containing mica quartzite.

Dongling stone is distributed in Yunnan, Guangxi, Guizhou, Beijing, Xinjiang and other places. The largest production of ore is in India, so it is also known as "Indian jade". At present, there are two kinds of aventurine stone, blue and red, most of which are opaque, occasionally a little translucent, and the hardness is similar to that of crystal.

Green aventurine was once known as Indian green jade, and its chemical composition is also dominated by silica, which belongs to quartzite. Aventurine jade is a quartz-like ore produced in Aksu, Xinjiang. Like Arowana, its chemical composition is silicon oxide.

The colors are usually green, yellow, pink, red, white, blue, and other colors, with green being the most common.

The general density of aventurine jade is about and the density of jade is about, so the weight of jade will be clearly felt by the two. The refractive index of aventurine jade is about, and the refractive index of jadeite is about. Although the density and refractive index of aventurine jade are very different from jadeite, due to its delicate texture, aventurine jade is also very beautiful after polishing.

<> aventurine jade has a characteristic, that is, it has a placer gold effect, what is the placer gold effect? Since the minerals of aventurine jade contain rutile, hematite, chromium mica, etc., some flaky mineral components will glow when exposed to strong light, and this phenomenon is called "eye". Good quality aventurine jade has many "eyes" that shimmer evenly on an oily green background, which is known as the gold dust effect, which is not found in jade.

Aventurine jade also has a more obvious feature, that is, it has a strong sense of oil. If you hold it in your hand and observe it, you will have a feeling of oil, whereas jadeite does not have this feeling of oil. Jadeite is generally glassy.

The glass light of aventurine jade is not heavy, and it has a matte and foggy feeling, while the jadeite has a rigid glass luster, which is dazzling and bright. The difference between aventurine jade and jadeite is mainly in different luster, different structure, different color, etc.

Aventurine jade is a type of quartz jade that is essentially crystal. Its bright color, vitreous luster, low transparency, and delicate texture are loved by some people. It comes in colors such as green, red, purple, and blue, with green aventurine jade being the most common.

Judging from the luster, natural jadeite has a glassy luster, while the glass light of aventurine jade is not heavy, and it looks like it is matte and foggy.

The origin of aventurine jade is India, it is a good jade, the difference between it and a goods jadeite is that the light transmittance is better, take the light or you can see the difference.

Aventurine jade, scientific name aventurine or aventurine stone, is called chromium-bearing mica quartzite in geology. Aventurine jade is a kind of quartz ore produced in Aksu, Xinjiang, the same as Huanglongyu, the chemical composition is silicon oxide, no fixed shape, usually green, yellow, pink, red, and other colors, green is the most common, turquoise - emerald green is the top grade. Its inclusions usually include microcrystals, pyrite, etc.

China has discovered aventurine stone in Xinjiang, which is locally known as "Xinjiang aventurine stone". - quoted from the encyclopedia.

Aventurine jade is revered for its green color, and in addition to its commodity value, it is also endowed with mythological colors. It is generally believed that aventurine jade has the meaning of driving away evil spirits and avoiding evil, attracting fortune and naji, and prolonging life, as a type of jade, it has been a symbol of identity and status since ancient times. Aventurine stone is a good carving material, which is a medium product in jade, and the status of Huanglong jade is about the same, and the status is lower than that of jadeite.

Aventurine jade is mainly composed of quartz stone. Quartz itself has no other color but white, but aventurine jade has experienced tens of thousands of years of crustal movement for a long time, which is doped with a lot of other trace mineral elements, showing a variety of different colors according to the type and quantity of elements, forming a variety of colors such as red, blue, green, etc., but green aventurine jade is the most valuable species.

Aventurine jade will become more and more oily when worn for a long time, and the same is true for other jades. Any jade can not be left empty for a long time, jade can absorb the surface oil of the human body as a protective layer to lock in the internal moisture, the longer the wear time, the better the gloss, the long time not to wear the jade inside the water is easy to lack of water, it looks boring.

<>1. The ingredients are different.

One of the main differences between aventurine jade and jadeite is that aventurine jade should be called aventurine stone technically, and it is a quartzite with a huge yield. Jadeite, on the other hand, is a jade-grade polycrystalline aggregate of stones, composed of jadeite minerals.

2. The color is different.

In addition, the color of aventurine jade and jadeite is also different, the color of aventurine jade has two colors, green and red, while the color of jadeite is mainly green, in addition to purple, yellow, blue, cyan and other colors.

3. The structure is different.

There is also a difference between the internal crystal structure of aventurine jade and jadeite, the internal structure of aventurine jade is a granular structure of quartzite, while the internal structure of jadeite is a structure of interwoven fibers.

Aventurine jade we call aventurine stone professionally, it is quite different from jadeite, the main content is as follows:

1. There are different types of jade:

1) Aventurine stone: It belongs to the category of "common jade, quartz jade, crystalline quartz jade, aventurine stone".

2) Jadeite: It belongs to the category of "common jade jadeite".

2. The main constituent minerals are different:

1) Aventurine stone: It is composed of granular quartz particles. Its constituent minerals are mainly crystalline quartz, and there may be a small amount of mica minerals, chlorite, limonite, hematite, goethite, clay minerals, etc.

2) Jadeite: a mineral aggregate composed of a variety of fine minerals dominated by jadeite. The main constituent mineral is jadeite, and the secondary minerals are omphacite, albite, albite, amphibole, tremolite, diopside, neonite, neonite, zeolite, as well as chromite, magnetite, hematite and limonite, among which omphacite will become the main constituent mineral in some cases.

3. Different colors:

1) Aventurine stone: It has a different color due to the fact that it often contains other colors of minerals.

1. Those containing chromium mica are green, which is called green aventurine (green aventurine produced in Xinjiang, China, contains green fibrous actinolite);

2 Those containing blue thread stone are blue, and are called blue aventurine;

3 Those containing lepidolite are purple and are called purple aventurite.

2) Jadeite: There are many colors, and the common colors are "white, colorless, various different shades of green, red, yellow, purple, black, gray" and so on.

4. Special optical effects:

1) Aventurine: Its quartz grains are relatively coarse, and the flake minerals contained inside are relatively large, and the flake minerals can show a sparkling aventurine effect under the sun.

2) Emerald: None.

5. The refractive index is different

1) Aventurine stone: , the point measurement method is often or, and it can be measured individually.

2) Jadeite: , the point measurement method is often used.

6. Different densities:

1) Aventurine Stone:.

2) Emerald:.
