(Synthesis of artificial diamonds)
Everyone knows Diamonds are hard and beautiful, but there are less people known a diamond could be the oldest material. Diamonds are found may be 50 to 1,600 million years old, the diamonds themselves are about 3.3 billion years old. This difference is because the volcanic magma that solidifies into rock where diamonds are found did not create them, but only transported the diamonds from the Earth's cover to the surface. Diamonds also may be formed under the high pressures and temperatures at the site of meteorite impacts, this is the nature ways to form diamonds, but there also have another ways to form diamonds-----artificial diamonds

An artificial diamond is a diamond that is produced by technology (manmade). First use high-pressure machines that need to weight several thousand pounds and the temperatures need to up to 1500 degrees. These conditions simulate the natural conditions which diamonds form. Other options include vaporizing carbon atoms and creating an environment that allows them to form a diamond structure.

Synthetic diamonds have many of the same properties as natural diamonds. These include cutting and polishing tools, and use in heat sinks there are more tools are being developed every day. Synthetic diamonds are also used in the jewelry industry, as they are very difficult to know which are real and which are fake. Two visual characteristics particular to man-made diamonds are not present in naturally occurring ones. Man made diamonds give off a orange glow under UV light and bear a GIA (Gemological Institute of America) "Laboratory Grown."

Artificial diamonds appear is because artificial is cheaper and also can have a same use compare to real diamonds, artificial diamonds also for people that can’t pay for a big price to buy real diamonds, although the price varies on different diamonds depending on the shape, cut, carat, clarity, and color. (0.50 carat can range...
