First of all, it must be clear that Mosan diamonds and diamonds are two different things. Mosan diamond is not a diamond, nor is it a synthetic diamond. The reason for the comparison is that they are so alike!
Diamonds can be divided into natural diamonds and artificial diamonds. One is a natural gem formed by carbon precipitation under special high temperature and high pressure, and the other is artificially cultivated in a short time by imitating the formation environment of diamonds. Their main element is carbon, while Mosan diamond is synthetic silicon carbide.
Whether it is natural diamond, synthetic diamond or mosan stone, it is difficult for ordinary people to distinguish bare stone used as jewelry after polishing.
Natural diamonds have been used in jewelry inlay for many years because of their high price, low output and uneconomical industrial use. Some synthetic diamonds are used in industrial fields, such as cutting tools, and some are used to replace natural diamond ornaments. Moss stone has been used in the field of electronics for many years, such as light-emitting diode materials. With the continuous improvement of people's synthetic technology of mosan stone, mosan stone has been gradually recognized as an ornament inlay. In terms of various physical properties, Mosan stone is also an artificial product very close to diamond. These three things are infinitely close in appearance, but they are different in essence.
In fact, mosan stone is not the product of recent years. Mosan stone is also divided into natural mosan stone and artificial mosan stone.
Fifty thousand years ago, a meteorite fell in Arizona, forming a huge crater on the surface, which was 570 feet deep and one mile in diameter. Some meteorite remains were scattered in the desert.
1893, Dr. Henry Moisan, a French chemist who won the Nobel Prize, discovered these glittering silicon carbide fragments in Diablo Canyon. 1905, this new gem is named after Moisan internationally to commemorate Henry Moisan's contribution to Mu Wasang's scientific and technological research.
Therefore, natural Mosan gems are very rare and can only be found in extreme environments, such as inclusions in meteorites, mantle rocks and even diamonds.
Slowly, people discovered that Mosang stone could be made by hand. At the beginning, American C3 Company invested 45 million yuan and began to develop Moshan diamond. 1980, the first man-made Mosan was born in North Carlo Laboratory. 1June, 1996, C3 Company of the United States registered a patent, introduced the market and started marketing.
In 20 15, its patent protection expired, because from the perspective of jewelry inlay, the appearance of diamond and Mosan stone is very similar, and Mosan stone is more colorful, so many businessmen gradually regard Mosan stone as a perfect substitute for diamond. Countries around the world have also begun to develop and produce. At present, mosan stones commonly found on the market are almost all produced in China, the United States and India. Up to now, 90% of Mosang exported in the world is produced in China.
? I'm a backpacker. I've been to India and Nepal, and I've met some jewelers and appraisers at home and abroad. I've been in contact with Mosan stone and diamonds. Let's analyze it objectively.
With the same quality of 1 diamond, Mosan and Huocai are different. Diamonds are radiant cold light, while fire colors are refractive warm light. Mosang fire color is more than 2.5 times that of diamond. Shine white light directly on the stone, and you can see the difference between them.
The constituent elements are different. Diamond is a carbon element, and Mosanite is a silicon carbide, which is basically indistinguishable from the surface or with a drill pen?
3 Different hardness, the hardness of diamond is 10, and the hardness of Mosan diamond is about 9.25. Glass can also be cut without damage to the stone itself. Although the hardness is high, both of them are afraid of violent bumps and impacts.
4 has different densities. When measured with diiodomethane (density: 3.32g/cm3), mosan floats and diamond sinks. If the Mosan diamond is cut according to the standard size of one carat, the actual weight will be less than 1 carat.
5 refractive index is different. When you look at it with a magnifying glass of 10 times, the cutting line of the diamond is clear and there are no ghosts, and there will be weak ghosts in Mo Sanshi.
6 The contents are different. Under the magnifying glass, the inclusions in diamonds are mostly in the form of clouds or dots, and rarely in the form of needles. The inclusions in Mosang are mostly columnar and flaky.
7, fire, diamonds burn in pure oxygen, will be directly sublimated, no impurities, Mosan diamonds will have combustibles.
If you don't understand the business, you can look at the certificate first. If you have some common sense, certificates can be completely ignored, because certificates can also be divided into true and false and categories! For example:
Because there is no specialized professional appraisal agency for Mosan diamond, it is difficult to see the quality of Mosan diamond from the certificate. Buyers can only determine the quality of Mosan diamond through channels or experience.
? In today's world, almost all you can see are China goods and Indian goods. Moss diamonds in the United States are the most mature, but they will only appear in a few big brand stores. A Franz Klammer mulberry is generally around 2000-5000 RMB. American-made Mosan diamond, waist code is engraved by product series, FB series is engraved with "Forever Brilliance", and FO series is engraved with "Forever One".
American Mosan is a laser code, and the certificate is not an anti-counterfeiting certificate, but a quality certificate.
The early certificates of Indian goods were mainly small cards (mostly global or GRS). Real Indian goods are generally rough when viewed with a magnifying glass 10 times, especially at the waist. Look carefully, many stones will have cracks inside, with white, yellow-green appearance and foggy surface. As time goes on, the fog will get worse, and the gems will turn black. The actual table is larger than the diamonds with the same carat table. Most Mosang in India have no waistline.
The quality of goods in China is uneven, but the overall quality is higher than that in Indian Mosang, and the stone stability is also very good. Okay, will Mosan change the fire color or color over time? All kinds of certificates are mainly heat, and the price is different with different quality. Another feature is that most Mosang diamonds in China will be made according to the same volume of Mosang. For example, in order to be more like a carat diamond, the actual weight of a carat Mosan diamond is generally around 0.88-0.95 carat.
The care of Mosan diamond is the same as other gems, because it contains natural mineral silicon carbide, and good Mosan diamond has stable physical properties, constant fire color and purity. Mosan diamond is lipophilic and will become dirty and dark after a long time. At this time, it can be cleaned with ordinary soapy water and a soft toothbrush. However, no matter what kind of jewelry you wear, you should avoid violent collision and store it separately to avoid scratching each other.
Like, "Who moved my cheese?"
1 diamond dealer, in the field of jewelry, Mosan undoubtedly affected the sales of diamonds. Many diamond dealers are very unhappy. I read some attack posts on the Internet, most of which were sent by jewelers. Mosan was even labeled as a "scam". Personally, I think it's a bit too much, because Mosan stone has always stated that it is not a diamond, including the certificate clearly indicating that it is Mosan stone. The market price is differentiated by quality, and it is reasonable to have a profit difference in the middle, which is no different from other gems, because the current sales process of Mosang diamonds lacks some intermediate channels, but Mosang diamonds.
2 Artificial cultivation diamond factory, although the artificial cultivation diamond is infinitely close to the natural diamond, it is not a natural diamond after all, and because the cost of Mosan is lower than that of artificial diamond, Mosan diamond is naturally cost-effective. It's normal to be criticized for touching someone else's cheese.
In the past, the channels of some brands were only in the hands of a few people and only sold in fixed channels. The emergence of WeChat business and purchasing omits intermediate links, and the operators of these brands are definitely not happy.
4 Deliberate hype, many marketing teams deliberately create negative news, spit on each other, attract more people's attention, and advertise for free. The biggest purpose is to sell.
5 earn traffic. Many so-called rational analysis is nothing more than trying to earn popularity and traffic through gimmicks. There are not a few copywriters who pretend to be experts, but they don't know what diamonds are and what Mosan is. What is the difference?
6 People who can afford diamonds or have already bought diamonds, you use thousands of dollars to achieve the effect that others use tens of thousands or hundreds of thousands. Can you understand this feeling?
Should I buy it?
Personally, if you want to make jewelry to decorate yourself and satisfy your vanity, you can buy it appropriately according to your personal situation, no problem. After all, it's a Brin thing, shiny enough. If it is to preserve the value, I advise you to think twice. It is really slim to wait for this thing to increase in value.
