Due to its atomic structure, diamond is the hardest natural matter. Save Energy Through Educational Games  By : Alistair Owens The world is changing through global warming. Our stocks of oil are reducing and pollution is growing concern. Now is the time to teach children through educational games of the task ahead of them to introduce renewable energy Isn't it time for the metric system to stop going around in circles?  By : Philip Yaffe The metric system has taken over the world. Meters, grams, liters, etc., are everywhere; the number of countries that don't use the metric system can be counted on the fingers of single hand. Now that it is so firmly established, it would seem appropriate to update it by adding a few more important measurements that still rely on cumbersome, old-fashioned non-metric units -- the hours of the day and the degrees of a circle. Are Those Diamonds Real?  By : David Cowley In some cases, people actually are after fake diamonds. Cubic zirconias, or manmade stones, are very difficult to tell from the real thing at least to the untrained eye. Some see absolutely nothing wrong with saving themselves some money by purchasing these if all they're after is the flash and brilliance of the stone. Of course, the difficulty in telling apart the fake from the real may save you some dollars but will make it all the more difficult to avoid being fooled. And for most, they want real diamonds in that engagement ring or earrings that will be a Christmas gift or whatever other piece they're shopping for. Facts About Rough Diamonds  By : David Cowley Before the late 1800s diamonds were found in riverbeds and traded to noblemen who recognize the value of this hard crystal and utilized the diamonds for armor studding in their breast plates. Later on kings and queens used the rough diamonds to adorn their crowns, tiaras and other jewelry. They were not as beautiful as polish stones however, they were still prized for their beauty and uniqueness. History Of Synthetic Diamonds  By : David Cowley Cut Glass was probably the first material used to simulate a diamond. It is readily available, easy to cut and polish and when seen from a distance, looks good. With all of the information available to today's consumer trying to pass cut glass off as a diamond rarely works. Cut glass is still seen in costume jewelry and in the movies today because of its extremely low cost. The use of cut glass has widely been replaced by the most popular diamond alternative, cubic zirconium. History Of Man Made Diamonds  By : David Cowley The experiment was successfully repeated by Ruffin in 1917 and again by Dr Willard Hershey in 1926. The diamond that was created by Dr Willard Hershey is on display in Kansas at the McPherson Museum. Despite the earlier success, the following experimenters had great difficulty in reproducing the required temperatures and pressures needed by the process and some of the experimenters even lost their lives to explosions. Diamonds And The Computer Industry  By : David Cowley Companies like the Gemesis, Apollo Diamond and others are producing quality diamonds and yet the price of the man-made or cultured diamonds are only about 15 percent less than mined diamonds. Gemesis and Apollo Diamond companies are using diamond jewelry business to finance their entry into the semiconductor industry, which is where the real money is. The 4C's Of Diamond Grading 101  By : David Cowley The Gemological Institute of America (GIA), the American Gem Society (AGS), and the International Gemological Institute (IGI) are the three most widely known and respected diamond grading laboratories in the world. Each of the grading laboratories have developed a very similar nomenclature for identifying the 4 C's of diamonds. The 4 C's stand for Carat, Color, Clarity, and Cut. We will also discuss the Shape of diamonds in this article. Facts About Man Made Diamonds  By : David Cowley De Beers started the very successful advertising campaign A Diamond Is Forever in 1947. The Advertising Age magazine has voted this to be the most recognizable advertising line of the twentieth century. This advertising campaign was designed to discourage diamonds owners from putting their old diamonds back into the market. The success of this campaign turned diamond into the symbol of eternal love and dramatically increased demand for the gems. Why Are Some Diamonds Colored  By : David Cowley The coloration of diamonds can be caused by several factors. Impurities trapped in the diamond during its formation, the crystal lattice structure of the diamond, and the exposure to radiation can all lead to the wide verity of colors available in diamonds. Facts About White Diamonds  By : David Cowley One thing that will remain a constant and that is that white diamonds are classic. The simple beauty of a white diamond is magnificent. There are so many jewelry possibilities that include the use of white diamonds. There are necklaces, bracelets, anklets, earrings, rings, and even toe rings and belly button rings. Nothing is off limits when displaying the sheer beauty of white diamonds. Facts About Yellow Diamonds  By : David Cowley Yellow diamonds are colored because of the impurities that are trapped inside diamonds when they are created. If a few of the millions of carbon atoms have been replaced by nitrogen atoms, then structure of the diamond will not be significantly altered but the clarity will be changed. The amount of color displayed is dependent on the amount of nitrogen involved. Facts About Pink Diamonds  By : David Cowley The pink diamonds comes in shades ranging from a pastel rose, such as the Pink Orchid to intense purple-reds of the Moussaieff Red, and the price is determined by the intensity of the color. Pink diamonds have sold for up to $1,000,000 a carat. Unlike the Type I diamonds that derived their color from impurities imbedded in the diamond, Pink diamonds are considered a Type II and get their color from a process known as Plastic Deformation. The Facts About Blue Diamonds  By : David Cowley When sunlight, which contains all colors, passes thought a diamond some of the light waves will be reflected by the nitrogen. The amount of color displayed is dependent on the amount of nitrogen involved. When we see color it is because the object we are looking at reflected a specific wavelength of the light spectrum. A good example of this is a pair of blue jeans. The jeans absorb all of the light except the blue light, which is reflected by the jeans. Facts About Black Diamonds  By : David Cowley Approximately 600 tons of conventional diamonds have been mined, traded, polished since 1900. But not a single black diamond has been discovered in the world's mining fields. The geological settings where diamonds are found or mined are virtually identical with the one exception, the Black Diamond. The Truth About Diamonds  By : David Cowley Diamonds have a mystique about them. Television ads portray them as the ultimate gift of love. Magazine ads want us to believe that a diamond is the only perfect gift to express love. If you plan on purchasing a diamond because you like how it looks or if gives you or your love one pleasure then by all means enjoy. If you plan on purchasing diamonds for investment purposes only you will need to do a lot of research to determine if this is a good idea. How Are Diamonds Made  By : David Cowley When one of the tectonic plates was pushed under another the bodies of the microorganism, now carbon, is also buried under tons of rock. The carbon is subject to extreme pressures by the rock pressing down upon it and by extreme heat, which is usually between 1100, and 1400 degrees Celsius. Could Time Travel Be Possible?  By : Patrick Omari Time travel is a subject that has captured the collective imagination and inspired countless works of science fiction. As well as inspiring works of fiction it is a subject that has been the topic of serious scientific investigation and thought. This article discusses whether time travel is indeed possible or impossible. Hydrogen The Future Energy Sources For Fuel  By : Archna Gupta On a summer day in Paris in 1783, Jaques Charles did something as tonishing. He roared 3,000 feet above ground in a balloon of rubber-coated silk bag filled with lighter-than-air hydrogen gas. Though this event had no significance for the next two centuries, yet Charles had launched a quest to harness the power of hydrogen for transportation.
