what is simulated diamond?

A long time ago,in school I learnt that Diamonds are the hardest substances known to man. This probably explains why diamonds cost so much. These diamonds are formed in nature. It is a geological process. Simulated diamonds are a creation of man; they are formed via a technological process. That is why they are also known as manufactured, lab-grown or cultured diamonds.

History of Simulated Diamonds

In 1797 it was first discovered that diamonds are comprised of pure carbon. Ever since then, attempts have been made by several people to produce diamonds synthetically.Many scientists tried to make simulated diamonds using a variety of processes. Chief among them were Ferdinand Frederic Henri Moissan and Sir William Crookes. But no one met with much success.The idea of making synthetic diamonds was also explored by the famous writer H.G. Wells in his short story titled. The Diamond Maker which was published in 1911.In 1941 an agreement was made between General Electric, Norton and Carborundum to develop the process of artificial carbon synthesis. But the project was halted due to the Second World War. However, it resumed in 1951 after the war was over.Eventually, in 1954 Howard Tracy Hall grew a synthetic diamond in a reproducible and verifiable process while he was working with General Electric. He even received a medal from the American Chemical Society for his work in 1972.These experiments were also carried out in other countries and they too reported some amounts of success in their experiments. Chief among them were scientists in Sweden who were part of the QUINTUS project of ASEA, and Iljin Diamond in Korea. The people in Korea, it was later discovered, had stolen the technology from GE via an ex-employee.

Simulated Diamonds: Technology

There are two major methods which are used to create simulated diamond crystals.The first and most popular method, which was devised by GE, is known as the High Pressure High Temperature (HPHT) method. There too, there are two different press designs which are used to grow the diamond crystals. The first is the method used by Howard Tracy Hall, which is called the belt press method. In the belt press method, two anvils, one from up and one from down, supply the pressure and heat currents to a cylindrical volume. The second method is known as the cubic press method. In this method, there are six anvils which provide pressure to a cube shaped volume.The second method, devised by the Japanese, is known as Chemical Vapor Deposition (CVD) method. In this method the necessary environment is created for carbon atoms in a gas to settle on a surface for the diamond crystals to grow.

Simulated Diamonds: Properties

Simulated or synthetic diamonds have certain peculiar properties as compared with the typical properties of a natural diamond. They are:The simulated diamonds may either be made up of a single continuous crystal, or they can be made up of several smaller crystals. The single crystal diamonds are used to make gemstones, while the smaller crystals are used in industrial applications.No natural crystal is pure, because it can contain many different impurities. They usually give color to the crystals, and even add certain properties (depending upon the properties of the chemical which causes the impurity). Due to the processes used in the creation of artificial diamonds, there are chemicals which have to be used in the process. For example, nitrogen gives the diamond a yellowish color, while boron gives a bluish tinge. Simulated or synthetic diamonds have many varied applications and uses. Due to their hardness diamonds have always been needed in machining tools. Due to cost and hardness factors, simulated diamonds are used on a wide scale in the various cutting tools.

Simulated Diamonds: Uses and Applications

Synthetic diamonds have also found their uses in the electronics industry. Conductive diamonds are used as electrodes in several cases.

  • Since diamonds are almost totally chemically inert, they are also used in the waste water treatment of organic effluents.
  • And of course, not to forget, synthetic diamonds are also used to make gemstones.
  • Thus, simulated diamonds are soon becoming the norm for various types of industrial and technological applications in the world.


    A simulated diamond is created in a lab while real diamonds are created through a heating/pressure mixture over thousands of years. You might have also seen something called "cubic zirconia" that's crap in my opinion. At least simulated diamonds have the exact same chemical composition as a natural diamond they just aren't made the same way. Cubic Zirconia is a totally different mineral completely. Here...


    More info on the diamond simulants/lab-created/manufactured diamonds.



    A real diamond as I've always refered to it is "diamond" I guess you could also try "natural diamond" as well. Also, wanting a diamond isn't always enough either. All diamonds are not created equal. You will need to learn about the value of a diamond. You can get a bigger real diamond that has a little less clarity for the same price as an almost flawless smaller diamond.

    It depends on if you want quality or quantity more.Here's some info you'll want to check out..



    You ll also want to know the three "C's" to get your moneys worth. Cut, Clarity, Color, and Carat.

    http://www.engagement-rings-guide.com/di the site above is GREAT!

    Another great test to use when you have a diamond and you want to know if it's real or not is to simply breath on it like you would a cold window to fog it up. Diamonds are unique in being able to dispense heat immediately, therfore they don't fog up! So if you breath on it and it fogs it's most likely a fake if not then you've got a real diamond in your hands and it may be worth purchasing.

    Helzbergs, Zales, and heck even walmart sell real diamonds and have rings in just about every price range. I got mine at Helzberg and they were really nice and I absolutely love my ring. I did hear from someone who knew a worker in the jewelry department at walmart that the diamonds are real but they are like the lowest grade/quality you can buy. That's why they are so cheap. I've never asked or worked there so I can't say for sure but just thought it was worth mentioning.ope some of this helps. For something that you are going to wear for the rest of your life it's worth reading up on. Good luck!
