Everyone knows that diamonds is the hardest gemstone and women all over the world go crazy to own a diamond jewelry. This beautiful gemstone is renowned for its lustrous beauty, but very few people know of its ability to be used in other fields like electronics, machinery etc.The two aspects of this gem stone are so diverse in association and nature that one does not really connect the two uses with each other.The diamond has certain very unique properties that enable it to be used in these various applications. It is the hardest substance on earth, has an extremely high thermal conductivity, is optically transparent and has high electrical resistance.The hardness property of the diamond makes it amenable to be used as a cutting tool, especially for hard substances like marble, granite and hard wood. It is embedded in mechanical tools to enable the shaping of engine blocks and automotive components.Once the process of developing synthetic diamonds was discovered, these synthetic diamonds were obviously the most preferred option for use in machinery. Apart from the cost, there are many other benefits of using synthetic diamond in tools. synthetic diamond growth can be controlled and monitored to produce desired shape and consistency. This is not the case with respect to natural diamonds where nature determines the shape, size and contours of the diamond based on various random natural events. Since the development of the synthetic diamond takes place in a laboratory, the level of impurities and mineral inclusions can be controlled. Due to these reasons and more the synthetic diamond today is sturdier as compared to the natural ones.Another property that lends itself to use in mechanical work is that of thermal conductivity. The type IIa diamond can conduct up to 5 times more heat than the metal copper. The fact that it can absorb high levels of heat means that it can be used to reduce the friction in many engineering parts. Including the diamond as a ‘heat sink’ helps in extending the life of the machinery since it avoids wear and tear due to friction and heat. ‘Slices’ of synthetic diamonds are also be used for other industrial and surgical tools.Much research is being done to use diamond chips instead of silicon chips in computers and it is being said that such computers would be 1000 times faster than the existing ones.Even though the diamonds were being produced synthetically in the early 1990’s, they had not made their appearance in the jewelry industry. Large synthetic diamonds could be used only by using a lot of energy and ultra-modern technology. Since the engineering and mechanical market needs were yet not being met completely by the synthetic diamond supply, the proliferation of the synthetic diamond in the jewelry industry was abated. Another reason why the synthetic diamonds did not make their way into the studded necklaces was the fact that most of the synthetic diamonds being produced were still yellow or brownish in color.The development and growth process of large diamonds required for the tools industry itself took too long. In 1990, De Beers claimed to have produced the largest synthetic diamond; a yellowish brown piece that was about 14.20 carats. This diamond alone took 500 hours to grow. Three years later they reported having produced a 34.80 carat crystal that took 600 hours to grow. Another few years and De Beers claimed that it was possible to produce 30 carat crystals in lesser time. But now one can find synthetic diamonds in many fancy colours and in white colorless shades too.Even though there were great obstacles in perfecting the art of making gem quality synthetic diamonds, some companies forged ahead and continued to research the process. The challenge that they faced was that they could not avoid the nitrogen from entering the diamond while during the process of production, the gas that gives the diamonds the yellow color. GE was the first company to produce an almost colorless synthetic diamond by eliminating nitrogen from the process. This was done by using a metal flux, a substance that melts and dissolves other material in it. Special compounds were added to the metal flux to keep the nitrogen from entering the process chambers. Even though De Beers had also discovered the art of making synthetic colorless diamonds, neither company released their experiments and the colorless gems that came from them into the market. However, a Thai-Russian joint venture in Thailand distributed lab made colorless diamonds in the market.Since the jewelry market does not require large pieces, these colorless synthetics are faster to grow, produce and sell in the market. Though the synthetic diamonds caters to a larger audience of the gem industry, they increase the possibility of being swindled, fraud and non-disclosure in the trade. As the production process is perfected and better quality colorless synthetics are produced and marketed each year, the challenge for the professionals in the jewelry industry becomes harder.Source: GIA
Synthetic diamonds are diamond crystals manufactured in laboratories through a technological process, versus natural diamonds, which are produced deep inside the earth through a geological process.
Synthetic diamonds are not to be confused with fake diamonds as we know it, like diamond-like carbon, which is amorphous hard carbon or diamond stimulants, which are made of other materials such as cubic zirconia or silicon carbide.
Synthetic diamonds are actually real diamonds; only they are produced in labs or are man-made, and depending on the process, can even be superior to natural diamonds.
The procedure of creating a synthetic diamond is relatively easier than mining and processing natural diamonds, which is why these stones are usually used in many industrial applications, such as drilling and cutting tools, as well as in electronics.
The process of producing these cultured diamonds was first discovered by French chemist Henri Moissan in 1892. This process created small diamond fragments by heating charcoal, which is carbon, to an extremely high temperature in a cast iron crucible.
It is then rapidly cooled by immersing the crucible into cold water, causing it to shrink, which then creates enough pressure to crystallize the molten carbon into tiny diamond fragments.
After Moissan’s process, the first commercial application of synthetic diamond production was developed by Tracy Hall for the General Electric Company in 1954.
This production process is known as the HTHP or high-temperature high-pressure, a procedure that has been improved upon and has been used to make industrial-grade diamonds to this day. Another main process being used to create synthetic diamonds is the Chemical Vapor Deposition or CVD method, which was first developed during the 1980s.
The HTHP technique applies a combination of heat and pressure on a diamond seed by using either a four-anvil tetrahedral press or a six-anvil cubic press. This is a process that attempts to replicate the natural conditions of diamonds formation inside the earth. The CVD method on the other hand, adds a vaporized carbon-plasma mixture with hydrogen, activated on the diamond seed using microwave energy, which then allows the gas to substrate.
This makes the diamond seed grow in successive layers.
Both procedures can produce cultured diamonds in a span of just several days. These stones can have the identical hardness, cleavage, light dispersion, refractive properties, specific gravity, and surface luster of a natural diamond, and may even contain small inclusions. Some cultured diamonds are even superior to their natural counterparts.
Just some of the known synthetic diamond manufacturers are Apollo Diamonds, Chatham Gems, Gemesis Cultured Diamonds, and Taurus Created Gems.
These companies create a range of lab diamonds, as they are also called, from colorless grade D diamonds to fancy diamonds.
Most synthetic diamonds will have a slightly yellowish hue because of nitrogen impurities that are present during its manufacturing.
These cultured diamonds can be distinguished from natural diamonds by using any of the following: infrared, ultraviolet, or X-ray spectroscopy. Its UV florescence can also be measured with a Diamond View tester.
If you are choosing diamond jewellery as a gift or as an engagement ring, it is essential you must to first know how to choose diamond jewellery for your loved one.
Understanding the basics of how to choose Diamond Jewellery will help you choose the best jewellery for your loved one.
The first place to start is the Diamond 4 C’s, these are:
Diamond Clarity
Diamond Clarity defines how clean the diamond is. Clean diamonds have no scratches, trace minerals or any tiny imperfections.
The clarity of the Diamond is one element that determines the cost of Diamond Jewellery.
Diamond Colour
Diamond Colour defines the grade of the diamond. As Diamonds are taken from the earth’s crust, most of the minerals are colourless. The most colourless and clear the diamond is, the more expensive the diamond jewellery will be.
Diamonds do naturally come in different colours. But it is essential you purchase these diamonds from a reputable Diamond Jeweller, like Acotis. Acotis only sell good quality diamond jewellery.
You should avoid diamond jewellers who may subject the diamond jewellery to artificial colouring or dying.
Diamond Cut
The Cut of the Diamond an important factor determing the cost of the diamond jewellery. The Diamond Cut shows sparkle and shine of the diamond jewellery. To be assured of high clarity, the diamond should have a big faced cut.
Diamond Carat Weight
Another important factor to consider is the Diamond Carat Weight. Your Diamond Jewellery weight will be measured in carats; one carat is equal to 0.2 grams. The weight of the diamond can have an impact on the cost of the Diamond Jewellery.
Choosing diamond jewellery is very much an individual choice. Our advice is to balance the weight with the quality of the stone. Achieving a larger size – If there is a limited budget and the size of the diamond is of the utmost importance, then slightly lowering the colour and clarity can help achieve the desired diamond size while remaining within the budget.
Diamond is the queen of all precious stones. It is not only rare but also has absolutely no equal in hardness. Diamonds have a wide color range and their reaction to light is to sparkle and scintilate. Besides being the hardest substance on earth it is extremely rare and beautiful. It is no wonder then that diamond and amethyst jewelry or citrine diamond jewelry or any combination of diamonds with one or more other precious stones is turning out to be very popular.
The dazzling diamond is actually just a miracle of nature. Diamonds come in a wide variety of colors and clarities and cuts. The size and weight of diamonds is normally weighed using the unit of measure, carat. When you decide to buy diamond and amethyst jewelry or citrine diamond jewelry you must take into account the cut, carat, color and clarity of the diamonds. Diamonds are available in various kinds of settings each of which displays it in a distinct fashion. Some of the more popular diamond settings include channels, chevrons, bezels, bars, prongs and paves.
Diamond and amethyst jewelry is one of the most beautiful forms of color stone jewelry. Diamond rings and more so diamond amethyst engagement rings and diamond citrine engagement rings are an all-time favorite with jewelry lovers. A diamond necklace is a desirable and luxurious jewelry gift. Diamonds set in gold are popular all over the world and Indians they say account for fifty percent of the entire world’s purchases of gold. Besides, there could be other precious stones set in gold along with the diamonds as in the citrine diamond jewelry.
Diamonds in settings of platinum also make great jewelry albeit a bit expensive. For those who look for elegance, they may choose a combination of colored diamond with any semi precious color stones. Citrine diamond jewelry in white gold settings is getting to be very popular with the modern generation. Rings with diamonds and amethysts set in them make great diamond and amethyst jewelry which can be worn with great versatility. You can also find bracelets, pendants and earrings set with amethyst or citrine with diamonds.
Despite the fact that diamonds are the hardest materials here on earth, they are brittle and therefore not indestructible. Amethyst and citrine are not nearly as hard and therefore one must make sure they do not wear any diamond and amethyst jewelry while engaging in heavy activity. Citrine diamond jewelry can be easily maintained by cleaning it with a soft brush and water and a small bit of ammonia. Make sure your diamond jewelry is stored in the velvet boxes it came in to make sure it stays free from scratches. Although diamonds were once upon a time a luxury item, today they have become quite affordable. The dazzle, little maintenance required and longevity of diamond jewelry more than makes up for the price. Hence diamonds are kept for some of life’s most special moments.
Diamond is the hardest naturally formed mineral found on earth. It is used not only for making expensive and beautiful jewelry but also for making drilling equipments. Since diamonds are very hard, they are ideal for making cutting and grinding equipments. Diamonds can be used to cut, drill, grind and polish. Thus it is greatly used in various industrial applications. Some of the common equipments used are the diamond tipped drill bit and the saw blades. Diamond powder is used as an abrasive in industries. The diamonds used for these purposes are of lesser quality and are called ‘bort’. Thus, there are two grades of diamonds – the gem grade diamond and the industrial grade diamond. The industrial grade diamonds should be hard and have heat conductivity.The demand for diamonds is greater than the supply, so the diamond drill is very expensive. Although, there are a number of types of drills, the diamond drill is a very essential piece of equipment in an industry that needs to do a lot of drilling. The diamond drill is actually a drill with the diamond drill bit attached to the end of hollow drill rods. The diamonds used are fine to micro fine diamonds. To keep the sharpness and hardness of the diamond drill, it is necessary to give it sufficient lubrication and cooling. The holes made are very clean and giving the best results. The drilling has to be done slowly so that the life of the drill bits can be extended for a longer period of time. Drilling is a laborious process. It is also a tiring and demanding task and uses up a lot of physical energy. But, it needs to be done. The diamonds drills can make holes in any type of substance, right from a soft one to a hard one. It includes bricks, metals, concrete and any other material without giving out much noise. The holes can be made quickly without any vibrations and much effort, since the drill is made of hard diamond. The diamond drilling equipments are long lasting and penetrate fast to drill a hole.The diamond drilling equipments are used in all kinds of industrial applications. We are generally not aware of it many uses. They are used by the construction industry for making holes in bricks, concrete and iron. It is used in the mining industry to drill holes at places where there are mines. Wherever holes have to be made for placing cables, where anchoring bolts have to be placed and also where load carrying machines have to be installed, the diamond drilling equipments are used.There are two types of drilling techniques. The dry drilling technique is used when concrete, hard surfaces, pavements, bricks or any hard surface has to be drilled. The wet drilling technique is used when the place that has to be drilled is fully under water. The diamond drilling equipments are of different types. Synthetic diamonds are used in the impregnated bit’s matrix series. The matrix layer has the diamonds in a powdered metal bond. They have a long life and also penetrate fast. They are used in many forms of drilling. Surface set diamond bits have a single natural diamond layer. They have a hard matrix compound on the face of the bit. They are used while drilling soft to medium hard surfaces.Diamond reaming shell has natural or synthetic diamonds. It is used to attach the drill bit to the core barrel. The main work of the reaming shell to make a hole that is exact in diameter for the core barrel to go through, having enough space for a new drill bit, when the old one has to be changed. Long diamond reaming shells are also available for drilling purposes.Diamond core bits are thing walled core bits that are used in a large number of applications. They are used to drill holes in are concrete, glass, ceramics and also in all kinds of pipes used in electricity, drainage etc. Wet cut drill core bits and dry cut drill core bits are available for various purposes.Synthetic diamond polycrystalline is also used in making drilling equipments. They are used in making drill bits, reaming shells, saw blades etc. Polycrystalline diamond pads or cutters (PDC) are placed in rows of polycrystalline diamonds kept on tungsten carbide substrate on the bit face, to drill holes in areas that are too sticky or soft. You have PDC core bits and PDC drill bits which are cost effective and very useful in drilling and cutting activities. The diamond drilling equipments are no doubt expensive, but they are very effective in making clean holes that are necessary for all construction, mining and power, drainage, gas lines purposes. We should check out the various companies that manufacture these equipments, obtain details about the equipments and the price and then order the equipment that we need. The internet would be the best place to gather all the information.
Diamond EarringsDiamond earrings are some of life’s most precious things. And what’s not to love about diamond earrings? These treasures are made from the toughest gems on earth. Their name has rightfully been derived from adámas, which is Greek for “unbreakable and untamed.”Diamond earrings, including diamond hoops, diamond loops, and diamond stud, have grown in popularity since the beginning of the 19th century. This is because of the improved techniques used in the cutting and polishing of diamond earrings, diamond hoops, diamond loops and diamond studs. At the same time, the world saw prosperity in developing global finances and increased supply of diamonds. The media had likewise increased the stature of diamond earrings, diamond hoops, diamond loops and diamond stud with strategically designed and targeted advertising campaigns. Diamond earrings todayToday, there is a steady demand for diamond earrings, diamond hoops, diamond loops and diamond studs. And it is more so if these treasures rank high in terms of the four Cs: cut, clarity, color and carat.The gem that diamond earrings, diamond hoops, diamond loops and diamond studs are made from originate mostly from the southern and central regions of Africa. This sums up to about 49% of diamonds. However, India, Canada, Brazil, Russia and Australia are all catching up in diamond mining and distribution. How to choose diamond earrings, as well as diamond studs, diamond hoops, and diamond loopsNot all diamond earrings, diamond loops, diamond hoops, and diamond studs are created equal.

In any and every given moment of your life, you are either in command of yourself, or you are being commanded. Guy Finley
Keeping a wardrobe that is complete and always new is rare. The costs of buying clothing today and with the constant change in styles, bargains are a treasure. There is a definite challenge to being well dressed at all times, especially on a limited budget. For working women this is difficult, yet, it can be done.
The key is in the planning. It takes money to build a wardrobe, or to start over from one season to the next. When you plan your wardrobe, keep in mind your particular style or look. If you find yourself asking questions like, What on earth will I wear today? Or, I have got absolutely nothing to wear! Another favorite is to telephone a few friends to see what they are going to wear. If you find yourself doing any of these, then, your goal is to plan.
Asking yourself some of the following questions may prove helpful:
Does your wardrobe consist of more than 20% of clothing you have not worn in over a year, thinking they may come back in style?
Do you own enough accessories to start your own craft store?
How often do you make impulse purchases?
Before purchasing, do you allow enough time to actually try on the garments?
Answering these questions may make you frown, but these fashion problems are not uncommon. Just realizing what your fashion sense is, is the first step.
Getting to know your own particular styles including the strengths and weaknesses of your figure type is a start. Make a point to focus on a clear image of what you consider being well dressed. Knowing what you like, want, and what looks well on you are important. Buy only what suits you best and not rely on the opinion of someone else. Nor should you base your decision only on what is currently popular.
Fashion is distinctive to each individual and does not need to be classified into a standard mold. Let your own taste dictate your fashion and beauty behavior. Pay attention to fashion and beauty magazines and adjust your taste to the fashions that are made available. Rather then being blindly led to something that may just be the popular style of the moment, adjusting your style is the better way to go.
Where do you start to build a best-dressed wardrobe? Start at the beginning and learn to stretch your fashion dollars by saving any clothing you already have. Make an inventory of what you have in your closet. Most of us usually make two main divisions. One is your summer-wear; the other is your winter wear. Stay within reason and keep anything that is still useful and in good condition. Just try not to cling to any clothing, even for sentimental reasons, that have not been worn for over a year. They only take up space.
Dresses, suits and coats are your most important investment and should be cared for properly. Upon removing them at the end of the day, be sure to immediately hang them up on their individual hangers. Check for spots and stains, and if necessary, brush them off and air them first before putting them away.
In dressing well, the other parts of your wardrobe include your shoes and accessories. Shoes are a major item and must be kept clean and in shape as often as possible. Constantly walking along cemented sidewalks can be a death march to your shoe heels and soles. Have them repaired as frequently as possible and discard shoes when they are unsalvageable.
Accessories are additional items that may be the central aim of your outfit. Give them your attention. Jewelry items must be sparkling clean. Any traces of tarnish on silver pieces can be cleaned with silver polish. Soap and warm water may be applied to jeweled rings, except on pearls, to remove dust and dried soap on the stones or settings. A little soap and water rinse, and even a little rubbing alcohol on many costume pieces can bring back the shine.
With a little planning, a lot of care, and special thought to your wardrobe purchases, you can add life to your clothing and have a closet that will rival any superstar. Dressing well is a sign of your self-esteem. And self-esteem is a part of your personal development. Without it, you may not be motivated to pay any special attention to the way you dress. Go do, and be well dressed!
Even if you have never been shopping for diamond jewelry, you have probably heard about the four Cs used to classify diamonds—clarity, cut, carat and color. These collective metrics are used throughout the world to determine the value of individual diamonds, with diamonds exhibiting the most desirable combinations of clarity, cut, carat weight and color rising to the top as the most universally unique and highest valued gems.
Clarity refers to the extent of inclusions, or natural features such as fractures present in the diamond that originated from its formation deep within the earth. A diamond’s cut describes the design and proportions of the diamond after it is crafted by a diamond cutter, an art form that manifests itself in the diamond’s outward appearance and brilliance. Carat is a concrete description of a diamond’s weight, with one carat representing a weight of 200 milligrams. Color is a diamond quality that generally refers to the extent to which a diamond is colorless. The Gemological Institute of America (GIA) has established a widely accepted color scale to rate diamonds falling in the normal color spectrum, which ranges from colorless to yellow. Diamonds which fall closer to the colorless end of the color spectrum are generally considered more valuable than yellow or brown tinted diamonds of equivalent clarity, cut and carat weight. Intensely colored diamonds are the exception, their rarity and beauty making them extremely valuable and exotic despite being far from colorless.
Although many people perceive all diamonds to be colorless, true colorless diamonds are extremely rare, and thus the most valuable on the GIA color scale. A majority of diamonds commonly used in jewelry such as engagement rings and eternity rings have a tint of yellow or brown, placing them in the normal color range. Though slight variations in the color of diamonds are to be expected, the difference among various shades is usually indistinguishable to the untrained eye.
While diamonds in the normal color range are the most common, diamonds form within the earth in an array of colorful hues. Diamonds in vibrant colors such as pink, yellow, green and blue, called fancy colored diamonds, are highly sought after by diamond connoisseurs and jewelry consumers alike. The rarity and splendor of such exotic diamonds contributes to their high value, and is the reason that colored diamonds are often attractions at museums and exhibits. The famous and fabled 45.52 carat Hope Diamond on display at the Smithsonian Institution since 1958 is a prime example, requiring dedicated security measures and personnel of its own.
Like white diamonds, the value of a fancy colored diamond is determined in part by the collective value of its four Cs. However, the color attribute becomes a more significant dynamic in the valuation of a colored diamond. Rather than being evaluated on its lack of color, a colored diamond is valued based on the quality of its hue, intensity and consistency.
