Diamond market demand prospects – tools, diamond, metal tools – metal industry

Category: Synthetic Diamonds — @ 2:18 pm

According to industry association statistics, in 2001 -2,009 domestic diamond production and sales growth from the 1.6 billion kt to 5.4 billion kt, average annual compound growth of around 16.4%. The next few years the market demand for our diamond can still be maintained at an average annual compound growth of more than 15% of domestic market demand in 2012 is expected to reach 6 billion kt. With the domestic diamond industry, technological progress and product improvement of the quality of synthetic diamond products in China have been gradually recognized international customers, according to industry association statistics, 2001 -2 007 years, the number of China’s man-made diamond exports increased from the 153 million kt to 927 million Carat, the average annual compound growth rate of 35%.

“As China continues to expand the scale of investment and infrastructure, the traditional process in the field of technology upgrade, the world’s manufacturing center, and new industries to the domestic transfer of factors driving the rapid development of China’s man-made diamond market with greater demand, showing a sustained and rapid growth the situation.

” March 16, China Crystal Diamond, chairman of the Greek left, said Guo. “Yellow Tornado and listed companies than the company’s product gross margins to nearly 10 percentage points higher than the company’s products also reflect the relatively high-end, technology is relatively ahead.” Zhengzhou, China for the upcoming Crystal Diamond, Lin Sheng Shun securities analysts think so. 2007, 2008, 2009, the company’s main business gross profit margin were as follows: 40.72%, 44.83% and 45.10%. Synthetic diamond products company in recent years, gross margin and net profit margin is high and the overall upward trend, showing that the profitability of the company stronger.

Merchants Securities, said Lin Yang Wu sponsor, has mastered the use of synthetic diamond raw materials, equipment, large-scale synthesis, advanced synthesis of the three major aspects of the core technology is the industry’s most complete technology and research and development capabilities of synthetic diamond production business, technical advantages are obvious.

As the company’s core technology patents are registered by a legal protection, so generally not been cloned. It is also because the company a strong core technology, enabling companies of the reporting period to obtain a good operating performance, gross margin was significantly higher than the same industry. This project is finished, normal years can be realized Sell Revenue 14,699.74 million (including tax), net profit of 4,830.61 million, the project pre-tax financial internal rate of return 27.54%, financial net present value of 15,578.36 million pre-tax items, the investment payback period of 6.24 years (before tax), project finance tax 23.30% internal rate of return, project after-tax net present value of 11,058.66 million in financial, investment payback period of 7.39 years (after tax).

Guo left the Greek description, even though our country closer to or reached the international advanced level, the proportion of synthetic diamond products continue to improve, but every year some of our country still needs to import high-end products to meet domestic market demand. China’s current imports of diamond export unit price unit price is 2.4-7.2 times, the Japanese market, the United States, Ireland, Korea, the average unit price is three products in China 3-10 times the U.S. market, Ireland, Korea, the average unit price the two products is China’s 3.5- 4.4-fold.

Guo stay Shetan commitment, the product unit price difference between on the one hand because of the huge diamond products in China and overseas famous enterprises are still gaps, more importantly, brand differences, it also shows China’s diamond industry technical standards and product quality are further room for improvement. Diamond industry, currently there are some technical level within the lower, small-scale production of synthetic diamond business, some companies will cut prices simply as ways and means of market competition, market competition order is yet to be standardized. In high-grade, coarse, high toughness of diamond output ratio, China is still and there is a big gap between the international advanced level. Current international and domestic markets high-end products are still mainly occupied by developed countries, the proportion of low-grade products in China, famous less difficult to meet the needs of domestic and foreign markets.

Diamond the Premier Mineral

Category: Synthetic Diamonds — @ 11:18 am

Diamond is a stable allotrope of carbon. Allotropy is chemically the ability of an element to exist in more than one form in the same physical state. The second allotrope of the same element is graphite. The characteristic different in the two allotropes is in their chemical bonding, where both are covalently bonded but their atomic combinations is different. In diamond, every single carbon atom is covalently bonded to 4 other carbon atoms, hence utilizing all delocalized electrons in carbon. Commercial properties of diamond including poor electrical conductivity are as a result of this chemical composition.

Chemical facts – physical properties of diamond

Physically, diamond is a shiny solid, crystalline in nature. It’s colorless and transparent. One of the best known qualities of diamond is its hardness. Mineral experts have argued that it is the hardest mineral in existence. The hardness of diamond is attributed to its intrinsic chemical composition (Thomas, 1991). Chemically, carbon, with an electronic configuration of 2, 4 require 4 electrons in its outermost energy level to attain stability. In diamond, this is achieved through covalent bonding where each atom combines covalently with 4 others. This implies that the 4 outermost electrons are effectively used up in bonding. The resulting structure from this combination is an octahedral structure that extends in all directions. The covalent bonds are very strong making it very hard to break it. The melting point is considerably high, estimated at 37000c.

Another common property is its poor electrical conductivity. This comes as a result of lack of delocalized electrons in its bonded structure. Recent developments have seen diamond being used as an insulator where it’s first doped with boron, an element that creates gaps within the octahedral structure making it possible to conduct. The Boron impurity also makes the diamond appear blue in color. The physical appearance of diamond is primarily clear colorless (Thomas, 1991). This is because it has a band gap of approximately 5.5eV. This band gap chemically corresponds to an ultraviolet radiation wavelength of approximately 225 nm. Other colors associated with diamond, principally originates from impurities and lattice defects. Using technology the impurities are introduced in diamond in a process referred to as chemical growth in diamond. The dominant impurity in diamond is Nitrogen which makes the diamond appear yellow or brown. Boron impurities make the diamond appear gray bluish. Other colors such as red and green are achieved through plastic deformation which involves the physical deformation/ disorganization of the diamond crystal.

Identification of Diamond

The principal identification method is based on the hardness and their high thermal conductivity (Boser, 2008). The material also has a high thermal conductivity, though this cannot be relied upon because other materials also exhibit a similar r property. In the Mohs scale, diamond follows quartz on the ability to cut glass so the ability to cut glass is not a conclusive test. Another test is the ability of diamond to scratch other diamonds though this normally results in the destruction of both pieces (Thomas, 1991). In the laboratory, special techniques such as spectroscopy, luminescence and microscopy are normally applied. In luminescence, the diamond is normally illuminated using shortwave ultraviolet radiations. Special machines are also used in identification. Diamond sure and Diamond view are specially made machines developed to test the authenticity of marketed diamond.

Natural Formation of Diamond

Naturally, diamond is crystallized from fluids containing high carbon content. This crystallization, achieved industrially is achieved using considerable amounts of heat and pressure. Heat needed is approximately 20000 F and 50000 pa of pressure. These kinds of pressure and temperatures are only found occurring at surfaces deep below the sea level. It is the belief of most scientists that diamonds form in depths well below 150 km below the earth’s surface (Hesse, 2007). The quantities of diamond enough to satisfy the industrial and commercial purposes are found in some geologically rich places scattered in some parts of the Earth’s continent. Most continents are formed of cratons which consists are the primary content of the earth’s crust formed approximately more than 2 billion years ago. Scientific dating has established that some diamonds could have formed more than 3 billion years ago. The current deposits of diamond are estimated to originate from volcanic rocks which are believed to have been deposited in strategic places through massive volcanic activities (Hesse, 2007). Deposit of diamonds available today is results of alluvial deposits which have resulted through weathering and movement by water. Strong winds and glacial movement have in the past contributed to transportation of diamond across different geographical positions in the Earth. Tectonic movements have also been credited with moving diamond deposits from great depths. Such kinds of deposits have been found in laces such as Kazakhstan. Diamonds found in this manner are generally of poor quality due to the intensive processes it has gone through which it is passed (Thomas, 1991). Meteorites have also been credited to formation of small deposits of diamond. The quality of these diamonds is generally of lower density. Some diamonds are estimated to form from extra terrestrial formations. There is possibility that most of the diamond in Africa and some parts of North America were formed in such processes.

Cutting of Diamond

For industrial and synthetic uses, diamond is passed through several processes. Natural diamond is normally rough. Due to its hardness, a lot of heat energy is needed to enable cutting. The cutting process includes laser cutting, sawing, cleaving and the final process of polishing. When cutting, the intention is to enhance the quality of diamond without losing a lot of quantity. About half of diamonds quantity is normally lost during cutting. The first step involves examination of the stone t determine the points of crystal weakness(Thomas, 1991). The cutter determines the planes that can easily be cut via sawing and cleavage. Present day cutters normally utilize the laser beam in achieving cleavage rather than traditional cleavage. The final process involves polishing the cut stone. The stone is considered polished when all of the facets are polished.

Judgment of Quality

When a diamond is used for jewellery, the properties that buyers should consider are clarity, color, carat weight and cut (Boser, 2008). Diamonds containing tainted colors of brown and yellow are considered of low value while special colored stones with tinges of green and orange, blue and red are considerably rare and hence of high value. Clarity is determined by presence of blemishes or not. Absence of blemishes ensures that the diamond cut is of great clarity. The carat weight is an attribute to the size of the diamond. The metric carat normally used for measuring diamond is approximately 0.2g. The cut quality reflects the quality of the processes of cleavage and polishing.

Uses of Diamond

Almost 80% of diamond normally contains impurities which lowers its color quality required in jewellery making. Most of it is used for manufacturing purposes. Since it is extremely hard, the metal is used in making hardy drill bits for cutting devices and in making surfaces that can withstand extreme shock (Thomas, 1991). Scientifically, it is used in photo detection and radiation and in experiments involving high pressures and temperatures.

Color Grading of Diamonds

Category: Synthetic Diamonds — @ 12:18 am

Most people don’t know this, but diamonds come in every color of the rainbow. Diamonds are made of carbon. When nature adds different elements to the carbon it creates different colors. Adding boron will give the diamond a blue color, nitrogen makes them yellow, hydrogen gives violet hues and so on. Most consumers are looking for the traditional colorless or near colorless diamond that is used in bridal and fashion jewelery in retail stores.

Diamonds are graded on a color chart that is recognized around the world. The chart starts with the letter D (think D for Diamond) and runs all the way to Z.
D, E, F, G, H, I, J, K … Z

Starting with the letter D and going to F are what are called colorless diamonds. These diamonds have an absence of yellow in them and are more rare to find in nature. They offer a beautiful white appearance but of course cost more because of the rarity of them.

Diamonds graded G-J are called near colorless.

These diamonds will have start to have a very slight tint of yellow and are more common in the marketplace. Typically all fashion pieces like necklaces, earring, bracelets, etc. are going to be in this quality. One of the reasons why is because a fashion piece tends to have many diamonds on it and if they were all colorless it would make the price spike fairly quickly. Near colorless diamonds offer affordability and allow the jewelry to have a higher total carat weight.

Anything running from K-Z is going to have a visible yellow color. The closer you get to Z the more yellow a diamond will have. It is around the Z range that you will start to see what some refer to as Canary diamonds. Just as a D color is rare, a Z is the same way.

The price for a diamond that starts to get close to Z with an intense or vivid yellow color starts to increase because of it’s rarity.

A jeweler trying to determine the coloring of a diamond will have a set of what are called master stones. These stones are made of a synthetic stone called cubic zirconia (CZ). These CZ’s are shaded from D-Z just as if they were real diamonds. The jeweler will hold a real diamond next to these master stones to determine the coloring of it. To tell the difference between a G and an H diamond is very difficult, even for a seasoned jeweler. Having these master stones is a great visual reference point for getting a more exact idea of what color the diamond is that is being looked at.

As stated before, most fashion jewelery is near colorless which is standard. But when you start shopping for an engagement ring, you’ll need to pay closer attention to the color of the diamond you’re thinking of purchasing. This is going to be the center stone of her engagement ring that she’ll look at forever and you sure don’t want it to be a dull or murky yellow. Here are a few pointers:

If you’re going to be putting the diamond into what’s called a solitaire (a thin band of gold or platinum with just the one diamond on it, no side diamonds) you need get a diamond in a color that’s going to be complimentary to the metal of the band. If you’re getting a white gold or platinum solitaire you need to get an H color or better. Anything I or below will have a yellow tint that will contrast with the white color of the metal and will make the yellow in the diamond very visible. If you’re going with yellow gold you can usually get away with anything because the yellow in the metal will blend with the yellow in the diamond. Keep in mind though that if you purchase a colorless diamond, even a D, and you put it into a yellow gold band, you might see some of the reflection of the yellow metal bounce up into the colorless diamond. It’s a very very faint reflection but if you think this might bother you, save the money and go for a G-H, they will blend and hide the reflection.

If you’re purchasing a ring that’s going to have side diamonds, you need to get a center stone that is comparable in color to the sides. There’s no need in buying a D if the side stones are an I. The beautiful whiteness of the D will make the side diamonds look dirty.

I worked in the jewelery industry for 7 years and have sold engagement rings from a couple hundred dollars to over fifteen thousand dollars. Here is my opinion:

Go for a G color. The reason is because it looks just as white as a colorless diamond without having to pay the price for one. Most people who purchase a colorless are doing so because it’s at the top of the chart and “high quality”. Almost 95% of the time that I would hold 2 diamonds next to each other, one an F and one G, and asked the customer to tell me which was which, no one could ever tell the difference. Typically you have to have a 2 color grade difference to see a change in color. That’s why jewelers use master stones, it’s hard to tell a G from an H or even more so from an E to an F. As an average consumer (even myself most times) you’ll usually have to strain to see the visible difference between an F and G but not the difference in the jump in price . The reason is because you’re jumping from the near colorless category to colorless. No real visible change, but a category change. Save your money and buy a G. It’s not like you’ll be walking around all day with 2 diamonds comparing them. A G is affordable, offers a wonderful color (or lack thereof) and will work with any ring you put it into, whether it’s a solitaire in yellow or white gold or it has side diamonds.
