There are records of agate deeds in both the Old Testament and Buddhist classics. In the east, it is one of the seven treasures.
Agate can be divided into chalcedony and agate. The original stone with uncomplicated color is called chalcedony, and the original stone with straight and parallel stripes is called striped agate (cut agate).
According to the color of the original stone, it is also called twisted agate and crimson agate. Recently, dyed black agate is generally called agate.
Agate legend it is said that Aphrodite, the goddess of love and beauty, is sleeping in the shade of a tree. Her son eros secretly cut off her shining nails and flew into the sky with them in his hand.

In Japanese mythology, there is a crescent-shaped green agate, which is one of the three great artifacts in Japan and is dedicated to the gods. Upload time of agate identification knowledge: February 2005-18 hits: 252 agate The chemical composition of agate is SiO 2；; It can contain Fe Al Ti Mn V and other elements, showing various colors, concentric circles and regular strips, and can also be divided into silk-wrapped agate, striped agate, moss agate, carnelian, onyx and so on.
Among them, red agate is the top grade of all colors of agate, so there is a saying in Gegu Yaolun that "agate is poor and has no red life". Agate can be classified according to the following conditions: (1) 1. Red agate Red agate is the ancient red jade.
Among the red agates, there are East Red Agate and West Red Agate. The former refers to the red agate formed by natural iron-containing agate after heating treatment, also known as "burning red agate", including bright red and orange red.
An East Red Agate, named after it came from Japan in its early years. The latter refers to natural red agate, including dark red agate and bright red agate. Agate unearthed in ancient China belongs to West Red Agate, which comes from the West, hence the name.
2. Blue agate refers to blue or blue-and-white agate. This is a kind of agate with very beautiful color, and the large size is a good material for jade carving.
People of high quality are dark blue. The second color is light.
Blue and white flowers are also beautiful. When they have pinstripe structure, they belong to the variety of silk-wrapped agate. At present, most of the blue agate products produced in China market are artificially dyed, with uniform color and easy to distinguish from natural ones.
3. Purple agate. Most of them are single purple, and the quality is as bright as amethyst.
The second kind of person is not bright enough, commonly known as "boring". Purple agate is rare in nature, and it is also dyed.
4. Green agate Green agate is not found in nature. At present, almost all the green agates in the Chinese jewelry market are artificially colored. Its color is dark green, and some colors are like jade, but experienced people can easily distinguish it from jade. Green agate is "thin" in color and green and crisp in texture; Emerald color "vigorous", texture emerald, tough.
5. Black agate Black agate. Black agate is rare in nature. At present, the black agate in China's jewelry market is artificially colored, and the color is thick black, which is easy to mix with other jet stones.
Its hardness is greater than obsidian. 6. White agate is mainly white or five-color agate.
Among them, there is a so-called white horse, which is produced in Liaoning Province in the northeast, accompanied by astringent and precious juice gambling. In fact, some of it belongs to white chalcedony, which is mostly used to make beads, and then artificially colored, which can be dyed blue, green and black. This kind of white agate is also a large piece of raw material for jade, and it is dyed well in the local area for use.
However, nature also produces some white agates, which are generally unpopular because of their incorrect colors, especially those that are gray-white, but they can also be used to make some cheap and low-grade tourism products or souvenirs. 7. Other colors of agate Other colors of agate can be named according to different colors.

You can see concentric circles, ripples, layers or parallel stripes composed of many different colors, such as gray, white, red, green, light brown and light blue. There is a saying called "a thousand agates and thousands of jade pieces".
In the gem circle, the aphanitic block with concentric layered, irregular ribbon and winding structure is called agate. The chemical composition of agate is mainly silicon dioxide, which often contains trace elements such as iron, manganese and nickel.
The crystal morphology belongs to aphanitic, with granular and fibrous structure, and the * * * body is often stalactite, kidney-shaped, nodular and dense. Agate has fat or waxy luster, translucent, conchoidal fracture.
The hardness is 7-7.5, and the texture is hard and wearable. There are many kinds of agates, such as striped agate, moss agate, water bile agate, cut agate and so on. Agate is one of the jades with wide distribution, tough texture, bright color and beautiful decoration in nature.
Agate is widely used. It can be used as medicine, gem, jade, jewelry, handicraft materials, abrasive tools, instrument bearings and so on.
Agate is a kind of gem,
Agate is hard, and polishing is labor-consuming. The color is flawless and can be used as various decorations.
According to historical records, wearing agate crafts is not only for decoration, but also can make people clear-headed, energetic and improve work efficiency.

Traditional Chinese medicine believes that agate is pungent, cold and non-toxic, and can be used by people who have difficulty in ophthalmology. Grinding with agate is very effective. Medicinal agate chips are left when carving precious stones.
Agate is one of the earliest familiar gem materials and has long been regarded as a rare treasure in the world. It is said that it can bring happiness and confidence to the wearer, be endowed with the mercy of God, and ensure their victory and strength.
The earliest inhabitants of Mesopotamia, the Samoan, seem to be the first person to use agate as souvenirs, rings, beads, stamps and other precious stones. Their axe crafts made of agate are now stored in the National Museum of American History in new york. The most unusual agate product is a wine glass with two handles, with a capacity of more than one pint.
The appearance of the cup is exquisitely carved with the design of sprinkling god Bacchus. According to historical records, this cup was made for the Roman emperor Nero, and was later owned and preserved by many people, and finally became the cup used at the coronation reception of the French king.

In addition to chalcedony, sometimes a small amount of opal or aphanitic granular time is found in the fine minerals that make up agate. Strictly speaking, without the characteristics of grain and pattern, it can't be called agate, but chalcedony.
Now some chalcedony without grain and pattern on the market is also called "agate", which is inconsistent with the meaning of ancient agate. Pure agate is white. Because it contains other metal elements (such as iron and nickel), it is gray, brown, red, blue, green, emerald, pink green and black, and sometimes several colors are mixed or appear alternately.
Agate blocks are transparent, translucent and opaque, with glassy to waxy luster. The hardness is 6.5~7 and the specific gravity is 2.65.
There are many kinds of agates according to the thickness and shape of stripes. Those with onyx stripes are called onyx, and those with red stripes are the most precious, called red onyx.
In addition, there are varieties such as banded agate, city agate, Tanagate, moss agate, red agate, zygote agate, sauce agate, cypress agate, arc agate, water bile agate, etc. ("chalcedony" in Li See Shizhen's Compendium of Materia Medica has no grain and no pattern, and there are also many jade raw materials.

Agate (agate)
The chemical composition of agate is SiO 2；; It can contain Fe Al Ti Mn V and other elements, showing various colors, concentric circles and regular strips, and can also be divided into silk-wrapped agate, striped agate, moss agate, carnelian, onyx and so on. Among them, red agate is the top grade of all colors of agate, so there is a saying in Gegu Yaolun that "agate is poor and has no red life".
What is agate?
Agate has a very long history. About 1 100 million years ago, due to crustal changes, underground magma erupted in large quantities. When lava cools, steam and other gases form bubbles.
When the rock freezes, the bubbles are sealed and many holes are formed. After a long time, the pores were immersed in a solution containing silica and condensed into silica gel.
Fusible components of iron-bearing rocks enter silica gel, and finally silica crystallizes into agate. Mineralogy belongs to chalcedony, which is a kind of chalcedony with different colors and annular distribution.
Generally, colloidal silica is gradually filled to the center along the peripheral walls of caves or voids in rocks, forming concentric layered or parallel layered blocks. Generally translucent to opaque, the hardness is 6.5 to 7 degrees, the specific gravity is 2.55 to 2.9 1, and the refractive index is 1.535 to 1.539.
Agate can be formed in all strata of geological history, whether igneous or sedimentary. So there are many agates, and the color difference is also great.
According to the different patterns and colors, there are names such as agate, moss agate and jasper agate. Agate is regarded as a gem or handicraft because of its rich color and aesthetic feeling. It can also be used to make bearings of precision instruments, agate bodies, agate mortar and other industrial supplies.
What is agate?
Agate is also a member of the crystal family. It is a hidden crystal family, and its hexagonal crystal shape is very small, which can only be seen clearly through a microscope. Agate can be divided into striped agate, wrapped agate, moss agate, breccia agate, leopard agate, water agate, moss agate, red agate, onyx and so on. Agate is a colorful gem with powerful energy and great therapeutic function. Ancient people used agate as a talisman to resist epilepsy and insanity.

People who live in nature worship it as a god. It has special curative effect on weak body, nervous system disorder and heart disease. Onyx is black or black and white, which is very powerful. The Greeks and Romans cherished it and often wore it as an amulet. Strengthening and protecting eyesight and promoting the recovery of physical vitality are closely related to heaven and earth. But onyx should not be worn with other precious stones. Black-brown and white striped silk-covered agate has been highly respected since ancient times, and it is a good companion for treating mental trauma and fighting depression. It can give people strength, courage and self-confidence, make people speak freely, bring good luck and attract honest and frank people.

What material is agate made of?
The main component of agate is silica, because it alternates with hydrated silica (silicic acid), so it is often layered repeatedly. Because it is mixed with oxidized metal, the color can range from extremely light to dark. Use salts such as iron, cobalt and nickel. Let them naturally penetrate into silicic acid gel, or they can be made into "agate" artificially. Natural agate may also be produced under similar conditions.
Agate has a very long history. About 1 100 million years ago, due to crustal changes, underground magma erupted in large quantities. When lava cools, steam and other gases form bubbles. When the rock freezes, the bubbles are sealed and many holes are formed. After a long time, the pores were immersed in a solution containing silica and condensed into silica gel. Fusible components of iron-bearing rocks enter silica gel, and finally silica crystallizes into agate.
Extended data:
1, maintenance method
First of all, be careful not to collide with or fall off hard objects. When not in use, it should be stored in a soft jewelry box. Try to avoid contact with perfume, chemical solution, soap or human sweat to avoid erosion and affect the brilliance of agate.
Secondly, we should pay attention to avoid heat sources, such as sunlight and stoves. Because agate will expand when heated, the molecular gap will increase, which will affect the quality of jade, and continuous contact with high temperature will also lead to agate explosion. Agate is generally placed as far as possible to avoid sunlight, and often wiped to keep it clean. If possible, you can occasionally add pure water to keep it moist, which will be more beautiful.
When not wearing small ornaments, it is best to put them in a dark and humid place, and the storage environment close to the original ecology of agate is the best. In particular, water bile agate has natural water during its formation. If the surrounding environment is very dry now, it will cause the evaporation of natural water, thus losing artistic and economic value.
2. Economic value
People generally judge the quality and economic value of agate by naked eye identification. Although modern technology is developed and there are many jade identification instruments, it is very inconvenient to use these instruments in the transaction process. Secondly, it can't solve the problem. The reason is very simple, and it will be limited by the environment. If we judge the quality and economic value of agate, the instrument will be useless.
It is impossible to carry out complex instrument operation at the trading site, so naked eye identification is always an extremely important method. There are many kinds of agates, known as "1000 kinds of agates and 10000 kinds of jade", so there are many identification methods. Usually, the grading standards are stripes, colors, transparency, cracks, impurities, sand cores and block weight. Except water bile agate, which is the most precious, it is generally best to match harmonious and pretty raw materials.
