What does the cat s eye jade mean?

Jade is a bright pearl in the history of Chinese national civilization, followed by the feminine jade, the moon is also feminine, according to ancient legends, only the feminine woman can go to the water to pick jade in the moonlit night, when the jade in the sparkling water is particularly dazzling under the moonlight. Of course, the most important point is that jade is not only an expression of external beauty, but also a manifestation of people's spiritual world and self-cultivation. The tenacity, gentleness, delicacy and humanity of jade have a great consistency, Confucius said

The gentleman is more virtuous than the jade". In his view, jade has eleven qualities and symbols such as benevolence, wisdom, righteousness, courtesy, music, loyalty, faith, heaven, earth, virtue, and Tao, but good materials are only the basis for making jade, and its value can only be finally reflected after being carved by artificial design. There is a saying called:

If the jade is not cut, it will not be made. "Because the level of jade handiwork is an important symbol that determines the quality of jade, it is important to say here that although there are many people who are obsessed with jade, there are very few people who really know how to collect jade. Why?

Because laymen generally look at its external beauty, often ignore its true value. For example, the ancients liked jade, not only because it was crystal clear, but it is said that jade is spiritual, it will be considerate, when you are young, it will absorb your aura for many years, and when you are old, it will be released and returned to you. In this regard, it is precisely because what we have done is still lacking, because the process of loving jade is actually the process of cultivating ourselves!

Generally speaking, opal is one of the chrysoberyls, with a cat's eye effect, that is, it shows the same light phenomenon as the cat's eye, flexible and bright, will change with the intensity of the light, and is also known as the oriental cat's eye, is a rare and precious gemstone, valuable and has a high collection value. The brighter the eye of the opal, the denser its internal fiber structure, the higher the value, so when purchasing, it is necessary to pay attention to identify whether its eyes are bright, if it needs to be irradiated with strong light to be obvious, then its internal fiber structure is not dense enough, and the value will be reduced a lot.

Cat's eye, along with diamonds, rubies, sapphires, and emeralds, is known as the world's five major gemstones, and is a precious gemstone. The luster of opal is like a cat's eye, flexible and bright, and full of variety.

Cat's eye belongs to the chrysoberyl group of minerals, which is transparent to translucent, with a hardness of 5 and obvious dichroism. Its colors are rich and diverse, the common ones are honey yellow, brown yellow, wine yellow, brown yellow, yellow-green, yellow-brown and gray-green, among which the most precious is honey yellow. The well-known sources of opal are in Sri Lanka, such as Tranabra and Gower in southwestern Sri Lanka, and opal is also found in countries such as Brazil and Russia, but the production is relatively scarce.

When choosing opal, mainly look at its color, eyeliner, weight, etc., the best color is extremely strong pale yellow-green, brownish yellow and honey yellow, followed by green, and then slightly darker brown. The worst ones are variegated and gray, but the yellow is whiter, and the ** is lower. Then look at the eyeliner, the eyeliner is straight and even, uninterrupted, not cloudy, not gray, bright and clear for the top grade.

The heavier the weight, the more valuable it is, and it is already rare to see one with a diameter greater than five centimeters.

Strictly speaking, "cat's eye" is not the name of a gemstone, but rather an optical phenomenon that appears on some gemstones. That is, when the hemispherical gemstone is illuminated with strong light, there will be a narrow and bright reflection on the surface, which is called "cat's eye flash" or "cat's eye living light", and then named according to what the gemstone is, if the gemstone is quartz, it is called "quartz cat's eye", if it is chrysoberyl, it is called "golden green cat's eye". There are many kinds of gemstones that may have cat's eye glitter, according to statistics, there may be as many as 30 kinds, in addition to quartz cat's eye and golden green cat's eye, the most common ones on the market are "pyroxene cat's eye", "aquamarine cat's eye" and so on.

There are many kinds of cat's eyes, among which Hetian jasper has a bracelet similar to a cat's eye, and agate also has an opal.

Opal is a type of chrysoberyl in mineralogy, which belongs to the spinel group of minerals. Chrysoberyl is a beryllium-containing aluminum oxide with the chemical formula BeAl2O4. The reason for its color is that the chrysoberyl mineral contains fluoride ions.

Primary mineral crystals are often plate-like, short-columnar crystals, and belong to the orthorhombic crystal system. The crystal morphology is often short columnar or plate-like. Cat's opal has a variety of colors, such as honey yellow, brown yellow, wine yellow, brown yellow, yellow-green, yellow-brown, gray-green, etc., among which honey yellow is the most precious.

Transparent to translucent. Glass to grease luster. Refractive index, birefringence index.

Dichroism is pronounced, dispersive, heterogeneous. hardness, density grams of cubic centimeters. Shell-shaped fractures.

Peephole. The reason for the production of cat's eye is that there are a large number of small, dense and parallel filamentous rutile mineral inclusions inside the chrysoberyl mineral, and the refractive index of rutile is due to the large difference between chrysoberyl and rutile in the refractive index, so that the incident light is reflected through the rutile inclusion, concentrated into a ray and formed a cat's eye, as shown in the figure "The same cat's eye is under different light sources", when the chrysoberyl is more opaque, the more dense the rutile filamentous inclusion, the more obvious the cat's eye effect. When a cat's eye gemstone is illuminated with a spotlight flashlight, at an angle, the cat's eye appears yellow to the light half and the other half is milky white.

If two concentrating flashlights are used to illuminate the cat's eye from two directions, and at the same time rotate the gemstone back and forth in the direction of the filamentous inclusion, it can be seen that the cat's eye line opens for a while and closes for a while.

The formation of cat's eye jade is due to the directional arrangement of the fiber structure in the jade, and the arrangement direction of the fiber body is extremely consistent, this special effect is very rare, so the collection of cat's eye jade is very valuable.

In addition, the key to the cat's eye is to see the color, the saturation of the color should be high, and the requirements of the general jade are different, the jasper cat's eye requires water head and feet, to put it in layman's terms, that is, the material must have a certain transparency, so that if the saturation of the color is very high, it looks like a pool of green water, and it looks like a drop of water.
