With synthetic diamonds, why are diamonds still so expensive?

Just because a synthetic diamond is synthetic doesn't mean it's cheap. Synthesizing a crystal clear diamond is not an easy task, and it is not necessarily much easier than a natural one.

Adding up the various costs, it may be more expensive than naturally synthesized diamonds, but the diamonds synthesized by heaven and man are too scarce and forced to be artificially synthesized. Therefore, synthetic diamonds cannot change the quality of diamonds at all, and can only do their best to meet the needs of more people for diamonds. Not all synthetics can be produced on a large scale, and not all synthetics are low-cost and low-consumption.

So from a cost point of view, the ** of diamonds will not fluctuate much. <>

The emergence of synthetic diamonds has not had a huge impact on diamonds, and another reason is that people's lives are getting richer and richer, not only wanting to live a good life, but also pursuing some spiritual satisfaction. In the past, diamonds were a luxury for many people, something out of reach. But now it's different, although it's still very expensive, but it's something that many people can touch with a little effort.

From the perspective of demand, more and more people will buy diamonds, and the demand for diamonds is increasing, but the supply of diamonds cannot show a state of short supply. In order to adjust the balance of the market, the demand for diamonds can only be controlled by raising the ** of diamonds. <>

Although diamonds are not cheap nowadays, they are not sky-high. It is also meaningful to buy a diamond for a loved one, a symbol of pure love. For many people, there is a special meaning for the time being, which is a symbol of pure love.

It can't be cheap, and if one day diamonds are as cheap as cabbage, no one will think of love when they talk about diamonds.

Diamonds, the reason why they are expensive, is not because they are really rare and permanent, but because its publicity effect is so good that it has formed a rare and noble image in everyone's mind. The reason why it is expensive is no longer because of its ingredients, but because of its existential significance. So, even if there is a synthetic one, it is still expensive.

Synthetic is fake, and real diamonds are hard to get, so the ** of a diamond is always so expensive, and it can't be cheap.

Diamonds must be expensive, because they are full of pure natural, how can the real thing be compared to the artificial one? **Still you get what you pay for.

Here's how to distinguish man-made diamonds from natural diamonds:

1. Surface gas method.

When buying a diamond, take a breath on the surface of the diamond, if the mist dissipates quickly, it means that the diamond is a real diamond, if not, it means that the diamond is a man-made diamond.

2. Professional identification.

If you look at it alone, you will notice that the difference between man-made diamonds and natural diamonds is not very big, but if you look at it professionally, you will see that there is a big difference. Therefore, when we buy diamonds, we still have to ask an appraiser to help us take a look, and if you don't know much, you can also find some professional companies to help us.

3. Observe the color.

Secondly, it is to look at the color of the diamond. It is important to know that the color of natural diamonds is very natural and pure, while the color of man-made diamonds due to technical defects is very heavy, such as brown and yellow. Therefore, when identifying a diamond, you can also start with the color.

4. Drip test method.

Finally, if you want to better distinguish man-made diamonds, you can also put a drop of water on the surface of the diamond when buying a diamond, if the water droplets do not disperse, it means that the diamond is real. If the water droplets are scattered, the diamond is fake. This takes advantage of the oil-hydrophobic nature of diamonds.

Artificial diamond is a kind of diamond carefully cultivated by professional technicians, its production cost is relatively lower, and the production method will be simpler, so there are many merchants selling artificial diamonds in the market now.

The shape of a man-made diamond is the same as that of a real diamond, and there is not much difference> market for man-made diamonds** is very good, and there are now many customers who choose to buy man-made diamonds. Because artificial diamonds are relatively cheaper, you can spend the least amount of money to buy the most jewelry, which is the main reason why artificial diamonds are so popular now. And now the real diamond is very tight, it is difficult for the average customer to buy high-quality diamonds, and the high-quality diamonds are very high, not all customers can afford, so now to buy artificial diamonds, or the best choice for many people.

In addition, there are many varieties of artificial diamonds, and no matter what kind of artificial diamonds customers want, they can buy them. And when buying artificial diamonds, customers can also develop the corresponding diamond shape according to their own preferences, regardless of size, regardless of the material of the diamond, can make jewelry that satisfies customers, diamonds are a symbol of a girl's status, exquisite diamonds can make the whole person look more exquisite, and more horizontal and high, so now buying diamonds is a must-have thing for every girl.

The proportion of diamonds in our daily life is very important, whether it is a small party or an important banquet, it is inseparable from the use of diamonds. Especially at weddings, a beautiful and exquisite diamond is the lifelong dream of every bride, so the market for artificial diamonds is getting bigger and bigger, and it is precisely because customers have more and more demand for diamonds. A perfect artificial diamond can bring out the beauty of the bride, make the bride look more elegant and generous, and the exquisite diamond represents the groom's deep and strong love, so if you want to get married, you must prepare a beautiful artificial diamond ring.

In fact, this kind of diamond is artificially polished, there is a difference, the purity of the real diamond is relatively high, but this artificial diamond has a lot of impurities, and the cost performance is not very high.

Artificial diamonds are some stones that are processed, and there is a difference between real diamonds, artificial diamonds are particularly cheap, and the purity is not high, and the cost performance is not high.

Artificial diamonds are a kind of diamonds born after segmentation technology and heat treatment, which are different from real diamonds, and the cost performance is not high, and it is even possible to buy fakes.

Hello dear, synthetic diamonds are real diamonds, which have basically the same chemical composition and crystal structure as natural diamonds. However, the manufacturing process of synthetic diamonds is based on advanced technology to simulate the formation conditions of natural diamonds under the earth's crust, which is the main factor that distinguishes synthetic diamonds from natural diamonds, after all, synthetic diamonds are essentially the same chemical, optical and physical properties and crystal structure as natural diamonds. Synthetic diamonds and natural diamonds can be compared to the ice in ancient glaciers and the ice in refrigerators.

Despite the differences in the places and conditions of formation, the essence is the same. Read the paragraph.

Diamonds are gradually formed under the high temperature and high pressure of geology, because the processing procedure of diamonds is very complex, the difficulty of mining is very large, very cherished, especially precious, so it is very expensive.

1. Reason 1: It is difficult to mine diamonds.

Scarcity is expensive, and the diamond itself has small reserves, which is naturally not low. As people need to mine diamonds underground, it also means that diamond mining is more difficult, and people need to invest manpower, material and financial resources to increase accordingly, and the cost of diamond raw materials will rise.

2. Reason 2: The processing process is cumbersome.

The mined diamond raw materials need to go through a series of processes before they can be sold, including sorting, cutting, grading, etc., and each link means an increase in costs.

3. Reason 3: People's enthusiasm for diamonds.

Diamonds are formed by geological extrusion and weathering over a long period of time. Because diamonds are produced in very small quantities and diamonds are very hard, they are so expensive.

1. Diamonds are pure or near-pure carbides, and they need to have enough carbon, high temperature and pressure to form diamonds. The diamond formation process is also quite difficult, as follows:

In addition to the burial conditions of 120 to 200 kilometers below the surface, the temperature must reach 1,100 degrees Celsius to 1,650 degrees Celsius, and the high pressure must reach 40,000 to 60,000 atmospheres.

After being buried underground for hundreds of millions of years, diamond-bearing magma needs the help of lava flows to reach the surface, where it must be attached to potash porphyry or kimberlite to become secondary ores. Or it can be washed by river sand and turned into secondary minerals.

2. Expansion. 1.What are diamonds used for?

1) Use diamonds as knives and drill bits: Because diamonds have very high hardness and good wear resistance, they can be used for drilling and grinding.

2) The diamond is crystal clear and very good-looking, so it will be deeply loved by everyone when it is made into jewelry.

3) Because diamond has high thermal conductivity and good electrical insulation, it can be made into a heat sink for semiconductor devices.

4) Because diamond has good light transmittance and corrosion resistance, it is also very popular in the electronics industry.

2.Why are diamond jewelry so popular with so many women?

1) The meaning and meaning of the diamond itself is not only a symbol of love, but also an ancient and traditional token of love, so diamond jewelry will be deeply loved by women.

2) Diamond jewelry is crystal clear, very beautiful, and able to attract the attention of women.

3) Diamonds are timeless, do not go out of style, and have collectible value.

Such diamonds are formed by the high temperatures of the geology. The diamond industry has a monopoly, and diamonds have a unique significance, and the number is relatively scarce.

Because the ** of natural diamonds is still less than the demand. There is only so much diamond output, but there are still many people who need sedan closed diamonds. Of course, the large-scale emergence of synthetic diamonds does divide some markets, but it is not enough to shake the status of natural diamonds.

And the cost of synthetic diamonds is not very low. Depending on the grading of synthetic diamonds, so will the formation and closure of spring fissures. At present, the synthetic cost of colorless diamonds with gem grades greater than two carats is more than 16,000, and the synthetic cost of yellow diamonds of one to two carats is more than 3,000 carats.

And natural diamonds themselves are rarer than **. What's more, natural diamonds and synthetic diamonds can be distinguished, so the two are not exactly the same. In addition, the rough channel is monopolized by giants, so the best natural diamonds are still expensive.

Therefore, the reason why natural diamonds** are still expensive is that the demand is still very high; Synthetic diamonds are also costly; The channel for natural diamonds is monopolized by giants.

In contrast, the stiffness of synthetic diamonds is still different from natural diamonds, but with fewer and fewer natural diamonds, it will become more and more expensive, because Wang Zhenchan is rare.

That's because scarcity is expensive, and the amount of diamonds on the market is relatively small, so it is not natural to say that the poor filial piety is expensive after all, and its bag is relatively large, and it will be cheaper if you are cautious.

Because of the high value of nature, the strength and rarity of the later synthesis cannot be compared with natural diamonds, and it is not a grade.

Imitations are not rare, coupled with artificial hype, natural and natural are more expensive than synthetic.

The stock of natural diamond minerals is not less than **, it should be more, and much more, it is not rare at all! It's just that it is controlled by some giants, and Wu Yuan releases a little bit every year, with the purpose of raising ** Ge Sanzai! Earn more money!

At present, the synthetic diamonds that can be made in batches are mostly used in industry, such as diamond grinding wheels, cutting knives, etc., and there are still extremely high requirements for gem-quality diamond synthesis.

Synthetic diamonds are not at all on the diamond he is through.

The technology of synthetic diamonds is mainly to imitate the environment in which natural diamonds are grown. In terms of the growth mode of crystal formation, synthetic diamonds can be roughly divided into three methods: one is the high temperature and high pressure method, the other is the seismic wave method, and the third is the chemical vapor precipitation method.

1. High temperature and high pressure method: the materials used in this method include coal, coke, graphite, paraffin, sugar, etc.; One report listed more than two dozen materials that had been successfully synthesized. Catalysts can be used for iron, cobalt, nickel, rhodium, ruthenium, palladium, osmium, iridium, chromium, tantalum, magnesium, or a mixture of these metallic elements.

It is required to reach at least 75,000 atm (atmosphere), preferably at a high pressure of 80,000 atm to 110,000 atm, and the formation temperature must be 1200 atmBetween 2000, preferably at 1400 ??1800.

The middle part of the reaction chamber is the high temperature zone, the carbon source is placed in this zone, and the crystal seed is placed in the low temperature zone in the lower part of the reaction chamber. With graphite as the carbon source, the crystal seed is fixed in the sodium chloride (salt) crystal bed, and a special crystal of the crystal seed is facing the metal catalyst, and a metal catalyst cylinder with a diameter of 6mm and a thickness of 3mm is placed between the crystal seed and the carbon source, and the metal catalyst is an iron-nickel alloy. After combination, it is placed in a one-way pressurized, four oblique surface three-dimensional ultra-high pressure and high temperature devices, and then put into a 1000 ton hydraulic press, the temperature of the reaction chamber is about 1450, the pressure is controlled at about 6gpa, and the growth time is 22 52 hours.

2. Shock wave method: It is mainly used to synthesize diamonds under the instantaneous high temperature and high pressure conditions generated by the first time, and the synthetic diamond particles are very small (commonly known as diamond powder), which is only suitable for industrial applications.

3. Chemical vapor precipitation method: firstly, hydrogen and hydrocarbon-containing potato fan gas (generally using methane CH4) are adjusted through a group of regulators to adjust the proportion of the two gases, and then the mixed gas is heated by using microwave wave sources or heating wires, etc., so that the temperature reaches about 2000, hydrogen and methane will be decomposed into a plasma flow formed by hydrogen atoms and carbon atoms, and then on the substrate heated to 600 1000, the nodules grow into a thin film.
