Briefly describe the gemstone, his color and fake color. The principle of Opal's color formation. Can I change the color from the color gem, why?

Come, copy Baidu Encyclopedia:
1. Opal
Ou Bo is the transliteration of English OPAL. Some people translate it into Australian treasure. It is a precious protein stone, which is mainly produced in Australia. In order to facilitate the keyword inquiry on the Internet, we still translate it into the "European" used in Chinese in the past. Opal originated from Opalus in Latin, which means "gemstone is beautiful". Opal is also known as: protein stones, glittering clouds, etc.
2. Original Opal
is a Chinese translation of Solid Opal in English, which means that the entire natural Opal after cutting and polishing contains parts of color and background lining.
3. The embryo body color
refers to the overall background color of the original Opal, English is called Body Tone.
4. Colorment game
Op surface color has changed various changes with the conversion of light and visual perspective, just like various colors to play hidden games together. English is called Play-OF-COLOUR. It is a phrase that is specially created to describe the changing colors of Opal.
2. Pleshus Opal
is a transliteration of English Precious Opal, which means precious or valuable Opal.
6. Deboho
is the transliteration of English DoubleTs Opal. It is the transliteration of English Triplet Opal. Chinese means three layers and one group of Opal.
8. Background lining stone
usually refers to the background part of the original Opal Opaline on the surface of the surface of the original Opali, Debola, and Cuibalo Opal. It is a natural ordinary Opal.
What is Opal
Ou Bo is one of the most beautiful and precious gems in the world. 95%of Opal in the world produced in Australia. Opal's chemical composition is SIO2 · NH2O (mixture of silicon molecule and water). According to the color of the Opal embryo body, it can be divided into colorless, white, light gray, dark gray to black. Unlike other gems, Opal's charming colors present various colors in the spectrum according to the random "color change game".
Mo is a gel -shaped or liquid silica left to the ground cracks and the cave is deposited and solidified into an unsplenged amorphous gem ore, which also contains animal and plant residues, such as trees, crustaceans and bones. The moisture content among high -level 5 Euro can reach 10%. Generally, the refractive index range of Opal is 1.38 to 1.60, and Mo's hardness range is 5.5-6.5.
During the formation of the Eubo, the silica solution is deposited like a gap and an empty mine in the inland strata like a magma. The sedimentary effect occurs at a depth of about forty meters from the surface, and the sediment of about 5 million years will increase the thickness of one centimeter. During this stage, the sedimentation of climate changes began to solidify with the sediments of climate change. Opal has not been bonded on other sediments, and it has passed for a long time.
We we usually divide natural Opal into two categories: "Pleshus Opal" and "ordinary Opal". Plaids Opal's colorful color and can show sufficient color change games, which is relatively rare and precious. The color is dim, and the color -changing game is called ordinary Opal. Ordinary Opal is found and produced in a small amount in all parts of the world.
95%of Opal's Oupang in the Opa Mining Area is ordinary Opal, usually only white, gray or black color. They are only suitable for the background lining of "Deboly Opan" and "Cuibalo Opan". The remaining 5%are some color level European, but 95%of them are just ordinary levels. In other words, only about 0.25%of the mining volume can be called a truly valuable Opal.
Plashis Opal is defined as silicon eggsstone that can be discolored. The term "color -changing game" is specifically used to describe precious Opal's beautiful and beautiful color. Obo produced in Australia is sometimes called "sedimentary gemstone" because it is mainly formed and produced in the sedimentary rocks in the Mesozoic Flora Basin. Plaospero usually contains 6-10%of water, and the small silicon particles it contains are discharged into regular patterns. Its Mo's hardness is generally between 5.5-6.5, and the proportion is mainly between 1.9-2.3.
During the silicon condensation process, the moisture gradually decreases, the gel forms a spherical shape, and the spherical body is naturally attached to the silicon of small grains. To. Although these balls are very small, they are full of Opal's interior and are very regular. Because they are round spheres, there are small gaps in structure (as if many marble balls are placed in the container after the gap between them), these gaps are arranged in three dimensions. The color of Opal is due to the decomposition of white light through optical diffraction of these rules. When the silicon particles are relatively large, the gap is relatively large, and red or orange diffraction light will appear. If the silicon particles are small, the same gap will be smaller, and the blue -purple spectrum will be decomposed through the diffraction effect. The color of the color is like a rainbow change. The strongest light diffraction effect is the largest gap size. Therefore, the surface of the red transformer Opal is often bright, and the blue color is relatively dim.
In short, the color changes of Pleuzupon comes from the diffraction of the gap between the silicon particles arranged and the gap between the rules. The diameter of the silicon particles determines the distribution of the color of the Opal. Small silicon particles will cause the usual blue -purple color, otherwise it will produce precious red. Each Opal has different values ​​according to its own quality. The main decisive factors are: embryo color tone, discolored game, color, brightness; patterns, size and shape.
The classification of Opal
2. Natural Opal
The natural Opal is directly mined and without manually handling pure natural gemstone. What we call the original Opal is the entire natural Opal that can be appreciated after cutting, polishing, and polishing on the basis of natural Opal. The following types of original Opal:
1. Black Oud
shows bright colors in the dark embryo color tone. We call it Black Opal. Lyburo, which is produced in Lydoning Rich, New South Wales, Australia, is the most famous and expensive Eubo variety. Black Opal does not mean that it is completely black, but it is deeper than Opal, which is lighter than the germ tone.
3. White Oupe
also called it "Milk Opal". White Opal presented light -colored embryo color tone, which is mainly produced in Kobpedi, southern Australia, Australia. Because of its shallow colors of the embryo, Bai Obo is relatively common. White Opal cannot show strong contrasting color like Black Opal. However, the colorful and high -quality white Opal also discovered from time to time.
4. Shuishi Oupe
To Shishi Opal is attached to an iron ore that can be separated from Opal, which can be produced, and is mainly produced in Queensland, Australia. This kind of Opal can only be cut with iron ore. The thin color Opal is wrapped on the surface of the iron ore. Because the dark iron ore lining makes the color of Opal's color look very beautiful. Shuishi Europe has different shapes and sizes. The small ones are like peas. Sometimes the whole piece of Shuishi Opal has a natural crack at the combination that can be divided into two halves, and there are two surfaces that seem to have polished. The thin surface layer of Opal is often destroyed during ore cutting.
5. Crystal Obo
Crystal Obo can be any of the above, but its embryo body color is transparent or translucent. You can even see other items behind Crystal Obo. Crystal Opal can have dark and light embryo color tones, so we call them "crystal black Opal" or "crystal white Opal" according to the depth of the embryo body tone.
The whole block of the mesh Opal filled in the gap between the fish tooth -tooth -like seams between the iron or iron ore. They usually have good -looking fire. Ada Mochaka cornerstone Opal can be soaked in sugar water, and then boiled in acid water to produce carbon accumulation, so that it has a dark background and even the entire cornerstone Opal to present a more beautiful color.
. Processing or synthesis
1. Synthesis
The silicon eggs with the same structure in the laboratory and natural European beacon are called synthetic European. The more well -known synthetic Opan brand is Gilson Opal. The following points are the difference between natural and synthesis:
*Synthetic Obo usually shows unusually bright colors, and color blocks are often greater than natural Opal.
*Synthetic color blocks of Eubo show a regular snake -like pattern.
*The production method of synthetic Opal cannot reproduce the complex color changes of natural Opal, so the transition of the pattern is unnatural.
. The counterfeit Opal
is placed in a clear hard plastic layer or epoxy resin. It is a pseudo -infla and imitation product that is easy to recognize.
3. Get Bolle Opal and Cui Bollero
This is a special hand -made gem. Debopo is a thin Opal and
black Background lining stones (usually dark ordinary European or light -colored ordinary Opal spray black
paint) with adhesives. Due to the thinner Opali Opal, Cuibai Opan is used to cover a layer of arc -shaped and transparent quartz material or glass on the surface of Duble Opal to enlarge the pattern and protect the surface of the Opal. Everyone usually uses them to imitate the valuable Black Obo, which is very beautiful but affordable. Here are some icons:
*The original Opal-is formed by the natural and thick Opal.
*Debola Opan is a thin Oupai double -layer handmade Opan with a black background lining as a base.
*Cuibalo Opan is a quartz or glass on the basis of Debopur to increase the color of Opal in the middle. Debopo and Cui Bolly Opal are relatively cheap alternatives in Black Opal. The disadvantage is that they are bonded with glue.
Terble Obo and Cui Bo Le Po
You should be familiar with what we call artificial gemstones usually refer to Debopo and Cui Boller Opal. It is to use natural silica glue to imitate the "original Opal" on the black background lining, so that Opal, which is attached to the black background lining, presents a more bright color. Of course, its price is much cheaper than the original Opal, because it actually has only a small piece of Opal.
1. Debola Opan: (double -layer Opal)
background lining stones can generally use black Opal stone without color, other light -colored ordinary Opal spray paint, opaque black glass or hard hard Plastic materials
Mo -thin Opal (usually crystal Ou Po or Bai Opan). Although it can be a variety of thickness, it is often thicker than the Opal in Cui Bolle Opal. The side is round, and the entire Deble Opal will have an arc -shaped surface. You can see its surroundings to identify Duble Opal. If the two pieces mentioned above are bonded with glue, you should be able to see a very straight sewing thread in color Opal and background lining stones. between.
2. Cui Boller Opan: (Sleeping Opal)
The black background lining stone is as exactly as used in Debopo.
The thin Opal is inlaid in it.
The very clear and transparent glass, quartz or plastic grinding into an arc and covered on the surface. Among them, European Po is usually very thin, and the transparent arc covering it on it makes the color more beautiful, some extent, to some extent It is also a protection for Opal.
Because Cuibalo Opan has an arc cover without any Opal, it is easy to identify. In addition, the surface of Cuibalo Opal and stone is more natural and softer than the light reflex on the surface of the stone. You can also see the sewing line next to Cui Bolle Opal to identify. In addition, if the material of the background lining is black plastic, it looks different from the stone. However, most of them still use black ordinary Opal and brown iron ore as a background lining.
. The preservation of Duble Opal and Cuibalo Opal n Because they are bonded with glue, soaking in the water for a long time will cause water seepage (this does not mean that it does not mean Your Opal will scrap it because of your rain). If it is infiltrated by the water, the fog phenomenon or gray will appear on the surface of Deblabo and Cui Bolly Opal, so you should often pay attention to its changes to avoid your Deblabo or Cui Boller Opal Say was penetrated.
Please note that many instructions about Opal will confuse your concept. Most of the general treatment for Opal is targeted at the original Opal, not the Dopero Opal and Cuibo and Cuibo Leo Bo. Only Duble Opali and Cui Bolle Opal need to avoid the penetration of the water and the original Opal does not need it. Debopo and Cui Boller Opan can often wipe with soft cloth and neutral detergent, but do not immerse them into the water. In addition, any Opal should avoid bleaching, chemicals and ultrasonic cleaning.
In short, although Duble Opal and Cui Bolle Opal are relatively cheap, they are also very beautiful accessories. Maybe the same beautiful original Opal needs more than ten times the price! Because the original Opal is relatively rare, many people use this processing method to allow everyone to have both the beauty of Black Opal and bear her price. Nevertheless, you should know what kind of products you are spending when you buy, and you should also know how to avoid your Deble Opal and Cui Bolly Opal. It is also necessary to seek the necessary identification certificate to obtain whether your Opal is a messenger information to avoid buying the mezzanine at high prices.
4. The usual misunderstanding and the correct concept
The correct concept of the wrong concept
Oupang should often be immersed in the water to prevent rupture of the original Opal. The structure of the bolt is non -perforated and sealed, which means that it is soaked in water, oil, or other liquids. Moving its surface fog and damage
black Opal is black (like black agate) Black Opal is a dark -colored Opal, does not mean that the whole gem is black.
The strong light will make Opal's leg color Opal rely on diffracted white light to present color. It will not fade because of strong light.
In oil rubbing Opal will cause it to damage and lose color. It is meaningless. It is meaningless.
This with glycerin, toothpaste rubbing or soaking in water will make Opal's reappearance of Opal. Because the slightly scratch surface in use needs to be re -polished to reappear (usually after many years)
Make in the liquid of rose red in the liquid of rose red The color presentation of the color of the color from the interior of Opal is due to the natural light diffraction effect
This warming Opal will enhance its high temperature and drought with extreme brightness and droughts will cause Opal to crack.
A valuable Black Opal can be more valuable than diamond
I Table in Opa
Because we love Opal, we are happy to tell our customers how to protect Opal, so that everyone can always be intoxicated For these beautiful personalized gems. Please read the following guidelines in a little time, which may be very useful for you.
The maintenance of Opal is actually easy, as long as you have a little common sense. Before you want to know how to maintain Opal, you should go to our "type of Opal" to understand what categories of Opal.
1. The maintenance of the original Opal
The original Opal is a more delicate gem, and the hardness is equivalent to glass, so it is very important to treat your original Opal to avoid damage. If you are preparing to deal with it Things may damage your Obo, you should first take off the worn jewelry (such as you are going to work in the garden, move furniture, etc.). Many people mistakenly believe that the original Opal could not be placed in the water, in fact, it was only for Debelo Opan and Cui Bolly Opal. There is no problem in the original Opal put in the water. In fact, most Opal itself contains a certain percentage of water.
If encounters extreme climate drought or temperature changes rapidly, Opa occasionally breaks down. So try to avoid extreme high temperature (boiling water) and extreme drought (desert) and the sharp changes in temperature.
3. Debopo and Cui Bollero
are different from the original Opal. The most important thing for Deblaeo and Cui Boller Opal is not to put it in the water. We also repeatedly mentioned this in other chapters, which will cause your Opal surface to fog.
3. Clean Opal
The original Ouki can be washed with warm water and cleaner and soft brush or soft cloth. Do not use bleach. Debopo and Cui Bolly Opan can be wiped with wet cloth and pollutant, but don't be soaked in water.
Men people to clean your Opal with ultrasonic, because strong microwave caused by vibration may break the original Opal. And ultrasonic cleaning also needs to put Opal in the water, which will make your Debelo Opal and Cui Bolly Opal penetrate the water.
4. Storage of Oubo
If you need to place Opal for a short period of time and put it directly in a soft cloth bag. If you need to store it for a long time, you should use cotton or wool products to drip a little water and wrap the original Opal and put them in a plastic bag. This is mainly to prevent the adverse effects of the climate from drying the climate.
In the 1980s, many Japanese businessmen made major mistakes on the issue of preserving Opal. They put the precious Black Opal in Liancheng in a specially dry box for a long time. In the end, they were surprised to find that Black Opal was cracked due to lack of water for a long time.
we hope that this description of this explanation is useful to you. If you have further questions and need to ask, please contact us immediately.
If of Opa
The power and disease of the sin and disease of the medieval superstition and legends comes from colorful stones. In the eleventh century, the Pope of Renne described Opal's: "It is the patron saint of the thief, and the keen vision of the stealing person in the night of Wuyun densely blocked the eyes of others." This The saying is to complain about the sinful spirituality of Opal's sinfulness to use it to become a talisman of thieves, spies, and robbers harmed the society.
The legend at the time China Eubo contacted unfortunately. A golden craftsman who made jewelry for royal jewelry suffered a disaster due to Opal. He accidentally damaged the expensive Opal when making Opal jewelry. Louis VI felt that his behavior was unforgivable, so he ordered it to cut it. Golden craftsman used to work. Since then, he and the same artisans who are the same as him have thought it was the disaster of Opal.
In the best -selling novel "St. Anne of Gilistan" (1829) at Walter Scott's best -selling novel "Gilstan's St. Anne" (1829). Together, the consequences caused at the time were unimaginable. In fact, most people do not read the third chapter of the novel carefully, but most people know the last plot of the novel -the heroine was given magic. When she touched the holy water, she lost the color on her chest. She died.
The famous gem scholars and businessmen Xiefraze carefully checked the above article in the "Journal of Gem Merchants". The discoloration of Opal is to remind the owner who has its owner to prevent poisoning. Even if many scholars are Opa Zhaoxue, the value of Opal during that period has plummeted in just half a year, and the gem market in Europe has been depressed for ten years. George F. Kenz said in "The Wonderful Knowledge of Beautiful Gem": "If you read Walter Scott's novels are not very careful, it will have a doubt about whether Opal brings bad luck. This wonderful novel, it In fact, there is no intention to associate Opal and Ido. "
It diamond merchants directly felt the threat of the diamond business they lived in the early 20th century in the early 20th century. Oud, with its bright colors, has always threatened the divertal consumption group to the diamond trade. Many diamond merchants protect their business by spreading rumors of "Opal and Own".
On the other hand, Opal is more delicate than diamonds. Perhaps because Opal needs to be treated more carefully, it is more powerful in the eyes of some people.
In fact, in the ancient Roman era, gems were amulets that brought good luck. Opal symbolizes the rainbow, bringing a beautiful future for the owner. Because its clear surface is metaphoric with pure love, it is also known as "Cupid Stone". Earlier races used Opal's tradition and quality of magical power. Opal allowed its owners to see the possibility of infinite future. Repressive.
The earlier Greeks believed that Obo gave the power that can be far -sighted and predicted in the future. The Arabs believe that they come from the heavens. In Arab legends, Opal is considered to feel lightning in the sky through it. The Romans believe that Opal will bring hope and purity.
In the 7th century, everyone believes that Opal has magical magic. At the end of the century, Shakespeare described Opal: "That is the queen in the magic gem". When the Orientals talked about Opal, they said that it was "the anchor of hope", and Opal was also respected as the birthstone of October.
, although some people in ancient times thought that Opal would bring bad luck, and we thought that if you did not have an Opal, it was a very unfortunate thing. A person who agreed with our view was Derry Harm Mo Mo Mo Mo Mo Mo Mo Mo He opened a famous Opal Store in the corner of a small town in Victoria. Dai Rui won a lot of lottery tickets in the 1960s and 1970s. He attributed the 200,000 Australian dollar bonus to Opal who brought him good luck.
How to buy
If you are not familiar with Opal, you will feel more blind and timid when buying Opal, and we understand your feelings very well. The reason why we provide you with as much as possible to provide you with information and information is to help you make the right choice during the purchase process.
Before buying, it is determined that what you see is Duble Opal, Cui Bolly Opan or Yuan Opal. Debopo and Cui Boller Ophan combine the very thin real Opal glue on the black background lining stones, making Opal's darker colors and brighter colors (imitating very expensive Black Opal). The advantage of buying Duble Opal and Cui Bolly Opan is a cheap price. But after all, the quality of the original Opal is completely different, and the purchase of the original Opal can also be called a long -term investment. After determining the original Opal, you should carefully observe which type of belonging to:
7, Black Opal
The royal family in Opal, because of their form and scarcity, the price is usually stable. Black Opal is also the highest quality Opal in the world.
8. Shuishi Oupe
is little known as the sister gem of Black Opal, but they have the same beautiful colors. Because the silica is thinly wrapped on the iron ore, the entire Opa contains the weight of many iron ore, so the price of Eubo per carat is cheaper than Black Opal. Smart merchants sell Shushi Opal use carats as units, and try to leave a lot of iron ore on the back of Opal when cutting. Because it is based on iron ore, Shushi Opal is harder than other Opal.
9. White Opal
The embryo color tone like milk, which is more ordinary. Such embryos are usually not obvious, but I have also seen the color of the color. White Opal.
10. Crystal Opal
The various Oupacon or above in Crystal Opal has a translucent or transparent embryo color. European.
Choose a Opal! They are unique, just like different people. The gorgeous red is the most valuable color tone on the black embryo body, but maybe you like blue, so why not choose a beautiful blue Opal? Red is the most expensive, then orange, yellow, green, orchid. Eubo is the best, don't pay too much attention to the color and embryo color tone it presents.
Y You should ask Opal to sign your seller to sign the authenticity guarantee (or identification certificate). This is not only to prove the value of the value or the need for the insurance company, but you should have such a purchase Habits make the responsibilities of both sides clear.
The read our "value of Opal" carefully, and learn more about how to determine the value of Opal and the usual principles relative to other gems. Although everyone is trying to try it, so far, there is no fixed formula for Opal's price in the world, and experience is always irreplaceable. You should always learn and practice more. In addition, it is a good way to buy from merchants with a good reputation.
If you check a Opal, first determine it is dry, and then look at the surface of the Oupang on the surface of the lights. Do not confuse the difference between the natural lines of the cracks and the surface of the Opal. There is almost no value. If Opan itself has any cracks, the sale to your seller should have a responsibility to let you know.
We must admit that you can buy Opal through the Internet. Some problems are really not easy to solve:
1. How do you know that you buy Opal in the photo?
2. Are you really willing to directly tell the personal credit card information directly to the seller who did not meet?
I think everyone knows.
