In our previous blogs, we have always told you to buy lab-created diamonds- they are made in the laboratory, just like the real mined diamonds. But have you ever thought how these diamonds are made in a mass? Actually, as a buyer, you don’t care about its formation. You just go and fetch it from a diamond store. But you should have a knowledge about its formation. Not just to know something new, but because you should know whether the diamonds are truly formed or not.

You may only know that Lab-grown diamonds are grown using two methods: High-Pressure High Temperature(HPHT) and Chemical Vapor Deposition(CVD). Right? If not then let us discuss that first in brief.

HPHT diamonds

There are three types of manufacturing processes in this method. Belt press, Cubic press, and Split-sphere(BARS) press. Just like a real diamond is formed under the Earth’s mantle with constant application of high pressure and temperature, such an atmosphere is created in this process. Placing a single small seed of diamond in carbon, the process of diamond creation is initialized using high temperature and high pressure.

CVD diamonds

In this method, diamonds are grown using hydrocarbon gas mixture. A thin slice of diamond seed is placed in a heat chamber having a high temperature, say about 800-degree Celsius. A mixture of carbon and other gases are added to the chamber to form your diamond. If you look through it properly, you will find, an overall ionization process is used. The molecular bonds between the gases are broken and pure carbon stick to the diamond seed.

CVD process is the latest way of creating lab-created diamonds. You can say, this process has taken the place of HPHT method. But why? Isn’t it helpful? Actually, the various advantages of CVD process have helped to it be preferred mostly. What are they?
1. Like HPHT, CVD process doesn’t need any high pressure to create such diamonds.
2. The CVD diamonds can be grown over larger areas when started with a larger diamond seed plate.
3. As it is grown inside a chamber, it is more environment-friendly as compared to HPHT process.

Well, both of the methods can bring out new dawn diamonds, CVD method is highly used now. Are you aware of the steps that are required to do so?

Let us see, what are the steps to create lab created diamonds or New Dawn diamonds.

Step 1:  In a diamond growth chamber, a collection of diamond beads are placed on a disc. A range of 15-30 seeds is usually taken. Thereafter, methane gas (CH4) is emitted to form a plasma with Hydrogen(H2).

Step 2: After the first step is initialized, the plasma ball is created in this gas chamber. This ball is filled with superheated gases and your diamond creating process is started. Isn’t it interested? As it is created then a disc made of 15-30 diamond seeds are placed in the microwave reactor.

Step 3: The next step is to raise the heat to 900-1200 C. This temperature is adjusted according to the type of gemstone.

Step 4: In this step, the Methane gas and the hydrogen gas stick to each of the diamond seed. These are referred to activated carbon-hydrogen species. The process is continuously observed for almost a month so that the crystal appears like a three-dimensional diamond.

Step 5: Technology has been raised in these days. Taking advantage, a techs monitor is used to check whether the seed is properly grown or not. The moment the iPad monitor indicates that the diamond is ready to remove, it is taken out of the chamber. But yes, not ready to serve yet.

Step 6: After the diamonds are removed they are directly sent to the gemologist for cutting, polished and grading. This gives the diamond a proper shape and quality. Later it is added to a metal base to form a wedding or engagement ring.

Is this blog helpful for you to gain knowledge on the formation of diamonds? Hope so. Just formation of diamond takes place in such a long process, but to get a proper diamond jewelry, a ring or a band, it is again molted to a metal base. So, why will it not be so expensive?

After a continuous process of formation, the diamond gets to achieve all the characteristics of a mined diamond. Remember the four characteristics of a natural diamond? These are similar to those. But how can you trust them? These new dawn diamonds are truly lab-certified diamonds. Without the certification by GIA labs, these diamonds won’t appear in the market. If any jeweler tries to sell you diamonds without GIA certificate, then it is your smartness not to accept that product. Because there will be a high chance of the diamonds not to be real. Instead, these may be diamonds stimulants. Go through our blog where we have clearly discussed how to detect the true diamond from a fake stone, and then make your purchase.
