The chemical formula is silicon dioxide. Pure colorless and transparent crystal is a variety of seasonable. The chemical composition contains 46.7% silicon and 53.3% oxygen. Because it contains different mixtures or mechanical mixtures, it has many colors. Purple and green are caused by iron (Fe2+) ions, purple can also be caused by titanium (Ti4+), and other colors are caused by color centers. The crystals contain sandy and fragmented goethite, hematite, rutile, magnetite, garnet and chlorite. Hair crystals are formed by inclusions containing hairy needle-like minerals visible to the naked eye. Containing manganese and iron is called amethyst; Iron (golden or lemon) is called topaz; Rose color containing manganese and titanium is called rose season; Smoke color is called smoke crystal; Brown is called tea crystal; Black and transparent are called ink crystals; The light green one is called stone pulp.
Question 2: What is rock crystal like? Ordinary people usually put a hair under the crystal to distinguish the authenticity of the crystal. If it is a crystal stone, you can see that the hair is split in two (the crystal ball is more than 40mm), but the well-made artificial crystal will also have this phenomenon! So, like the identification of other gems, there is no other way to identify true and false except knowing more, but it is certain that glass is the kind without birefringence ~ but at present, the possibility that the following crystal is false is relatively small! 1. Ghosts ... pillars ... caves ... clusters: At present, crystals cannot be synthesized artificially.
2. Defective R: It is difficult to synthesize crystals with defective R artificially (or clouds are also stone crystals).
3. There are ice cracks: not necessarily, but there will be no cracks when artificially synthesized, but it may fall out when it comes out.
4. Pure and transparent crystal: 99.99% is fake, and the bigger the crystal, the less likely it is to be true. Really, pure and transparent crystal at least 10 thousand pieces!
5. There are bubbles: with a magnifying glass of ten times, there are water-drop-shaped and quite regular bubbles, which are probably all artificial.
6. Transparent white crystal, pure purple and topaz are often artificial objects.
Ps: Generally, powder crystals will not be faked, because powder crystals are already very cheap. Man-made upside down, what if there is no salary? PS2: White crystal, amethyst, topaz, clouds, ice cracks, ribbons and so on are all natural! It's not fake ... In addition, natural amethyst and topaz are soaked in water in a white magnetic bowl ~ you will find that their colors and ribbons are obvious! In addition, the crystal will look very "water soluble"! Watch this slowly and carefully ~ put it in water ... the color will be lighter. Usually you don't need to use instruments to distinguish crystals ~ you can usually do it with the naked eye! In addition to AA amethyst, topaz and white crystal without ice cracks and defects, the instrument also includes polarizer, refractometer and hardness tester. However, crystals also have birefringence, and only glass does not, as mentioned above. The hardness tester is used to test whether the hardness is enough! Of course ~ try not to buy purple, white and topaz from all over the United States! There are thin crystal pendants, such as constellations, idols, big satellites, earrings and so on. These all appear in the United States, so there is a great chance to grow crystals ~ you must pay attention to their internal lines to judge! new
At present, it is found that fraud is
Thick hair and hollow hair crystals in the middle are neat (fake) new 2.
Some crystal columns are dyed and have strange colors. A hair crystal color actually has two colors (fake) new 3.
Have you ever heard that fake American ice seed powder crystal is valuable? ! Xin 4
The price of the crystal cave is too low, and it has been broken for a long time. This is to repair too many crystal holes.
Generally, almost all crystal holes have been repaired, but the crystal holes on the market are rarely repaired! Don't worry!
If the manufacturer promises not to repair it, the price of the crystal cave must be amazing.
Question 3: What kind of crystal is a real crystal with better thermal conductivity than amorphous glass, so the following text is a double shadow passing through the crystal, which looks a bit vague. During the long-term growth of rock crystals, some impurities will be wrapped in them (we call them "cotton"). If the feeling on the hand is not obvious, the crystal that is cool for a long time will be covered by heat, while the glass feels warm because the crystal (including synthetic crystal) has birefringence. Because crystal and synthetic crystal are both crystals, they feel very cold to the touch. Put a big crystal ball or crystal ornaments on a newspaper or book, the color is even, most products are pure (occasionally you can see some small bubbles), and the color of the crystal is soft and natural. What needs to be reminded here is that you can't hold it back. And synthetic crystal or glass products. Glass products can be seen clearly, and can be put on cheeks or other sensitive parts for experiments. Because of artificial control in the laboratory, it is unnatural.
The third trick is to feel cold and hot.
The second trick is to pay attention to the film "Look and Touch" so as not to be "slaughtered"
The first trick is to look at inclusion.
Question 4: What is the best crystal? The discrimination of crystal:
Specific gravity: too light must be false, so that imitations such as glass, plastic and pressed particles can be excluded. However, there are many crystals on the market now, the weight of which is similar to that of rock crystal, so it is not easy to find the authenticity by hand.
Refractive index: most people like to look at the crystal under the lamp, so they can't judge whether the crystal is true or not, but only the grade of the crystal, because the refractive index of the crystal is very high. We can put the crystal in a dark place. The color of the rock crystal will be very bright, and the color of the crystal will be dim, lacking the sense of "spirit" and only slightly bright. You can use natural white crystal and glass to compare and feel it.
Price: Crystal cultivation is similar to natural gem-grade crystal, that is, the crystal is extremely transparent, with almost no stone particles, but the price is very different. Usually, crystal training bracelets will be cut into sections. Crystal is transparent, but the price is generally not too high. However, if it is really a natural gem, the price must be above 100 yuan, depending on the size of the crystal.
Color difference: Crystal has color difference, so every part of a crystal can't have a uniform color, such as topaz, which is rare in the market. Natural topaz can be identified by putting it in water. Natural topaz is uneven in color in water. Usually one color radiates to the whole crystal, which is yellow, so the crystal color is absolutely uniform.
Others: it feels very cold, and the crystals with stone lines are basically not fake.
Inclusions: If there are inclusions, there will be no fakes, so you can buy crystals with inclusions such as hair crystals and ghosts with absolute confidence, because the cost of forging such things is very expensive and laborious, and the effect is easy to see through.
There are generally the following kinds of fake crystals on the market: 1. Glass products. Melted crystal 3. Lead glass. Synthetic crystals. Regenerate crystals (crystal culture).
Question 5: What is Class A crystal 3A A? It is the size, color, clarity and some special inclusions of grade crystal defined by insiders that directly determine its value, so A stands for good, and 3A is better. The state has no regulations. These regulations are all artificially added.
The price of crystal can only be comprehensively evaluated from many aspects. Of course, titanium crystal at present. Jin Fajing. Green ghost is more expensive.
Tourmaline's good interfaces are sold by carat, and there are dozens or hundreds of them per carat. Beads are sold by the gram. Blue tourmaline is more expensive!
Question 6: What kinds of gold crystals are there: ivory crystal, white ghost, white tourmaline, white agate, etc.
Wood crystal: green crystal, green ghost, green hair crystal, green tourmaline, green agate, amethyst, etc.
Water-based crystals: black crystal, tea crystal, nigger, obsidian, black tourmaline, blue crystal, aquamarine, black agate, etc.
Fire crystal: red crystal, red ghost, red hair crystal, red tourmaline, red agate, garnet, amethyst, etc.
Earth crystals: topaz, yellow ghost, topaz, agate, yellow tiger eye stone, topaz, etc.
Question 7: What are crystals made of? Crystal is a colorless and transparent timely crystal mineral. Its main chemical composition is silicon dioxide (SiO2), which is a substance "born out of the womb" with ordinary sand. When the silicon dioxide crystal is perfect, it is a crystal; Silica becomes agate after gelatinization and dehydration; Water-containing silica gel becomes opal after solidification; When the particle size of silica is less than several microns, chalcedony, flint and secondary quartzite are formed. Crystals have many colors because they contain different mixtures. Purple and green are caused by iron (Fe2+) ions, purple can also be caused by titanium (Ti4+), and other colors are caused by color centers. The crystals contain sandy and fragmented goethite, hematite, rutile, magnetite, garnet and chlorite. Hair crystals are formed by inclusions containing hairy needle-like minerals visible to the naked eye. Containing manganese and iron is called amethyst; Iron (golden or lemon) is called topaz; Rose color containing manganese and titanium is called rose season; Smoke color is called smoke crystal; Brown is called tea crystal; Black and transparent are called ink crystals; The light green one is called stone pulp.
Pure crystals are colorless and transparent crystals, which can hardly be found in rock crystals without impurities. Most rock crystals contain bubbles, impurities and crystals are mixed.
Artificial crystal is made of quartz sand through a series of processes, and then through fine cutting technology and flawless polishing. The crystal is pure and transparent, which makes up for the deficiency of rock crystal. Artificial crystal can enhance the refraction of light by adding metal elements such as lead, making the crystal more noble. However, due to the complex technology of artificial crystals, some of them are even more expensive than those in rock crystals.

Question 9: What is a crystal? The mineral name of crystal is Yingshi, which belongs to Yingshi family in mineralogy. Yingshi is one of the most common rock-forming minerals in the earth's crust, and it is also a kind of gem with a large number and wide application range in the jewelry industry. Seasonal gemstones can have a variety of crystal forms, such as obvious crystals and aphanitic, among which single crystals are collectively called crystals in jewelry industry.
The chemical composition of the crystal is silicon dioxide (SiO2 _ 2), which forms a colorless and transparent crystal when it is pure. When trace elements such as Can and Fe are contained, different types of color centers are formed by irradiation, resulting in different colors, such as smoke, purple and yellow.
Of course, on the other hand, there are specific commercial differences among starting crystals, titanium crystals and ghosts according to the types or arrangement of inclusions in crystals.
Question 10: What is a crystal? Crystal is a colorless and transparent large-scale timely crystal mineral. Its main chemical composition is silicon dioxide, which is a substance "like ordinary sand". When the silicon dioxide crystal is perfect, it is a crystal; Silica becomes agate after gelatinization and dehydration; Water-containing silica gel becomes opal after solidification; When the particle size of silica is less than several microns, chalcedony, flint and secondary quartzite are formed.
The chemical formula is silicon dioxide. Pure colorless and transparent crystal is a variety of seasonable. The chemical composition contains 46.7% silicon and 53.3% oxygen.
