How lab diamonds are grown

The beauty of diamonds cannot be undermined. As a result of its magnificence, beauty, and splendor, it has become, to many, a large part of their dressing while to others; it has become a must-wear for them as a part of their daily dress code. The fragile yet eye-catching nature of diamonds has made many persons ask the question, “how are diamonds grown”? If you have thought about this prior, you will find this helpful.

How are natural diamonds gotten?

 To get a carat of natural diamond, about 100 square ft of land must be disturbed, and a mineral waste of about 6000lbs must be created.

Is the production of lab diamonds high risked?

Of course, it is. As a consequence of the high risk involved in getting and mining natural diamonds, the needs for lab diamonds arose. An Example of the high-risk nature of natural diamonds is:

  • In a year, about one thousand workers who participate in mining natural diamonds sustain one injury or the other. In contrast, the production of lab diamonds results in no injury at all.

How are lab diamonds created?

Lab diamonds, which are also known as human-made diamonds, are made in the lab with the use of cutting edge technology. This technology creates the diamond by replicating the natural diamond growing process.

There are two ways in which these diamonds are being produced. Each lab decides what method will be best for them. The two ways are:

  • The use of the HPHT that is the High-Pressure Temperature

This type of diamond is made either by belt press, BARS or split sphere press, or the cubic press. Each of these process creates a very high temperature and a high pressured environment that aids the growth of diamond. These diamonds start growing as small diamond seeds in carbon. Then, with a temperature of about 1500 degrees Celsius pressurized to a square inch of 1.5 million pounds, the carbon will begin to melt, and the diamond will start to form around the starter seed. After cooling, it forms a pure carbon diamond.

  • The CVD. That is the chemical vapor Deposition.

This type of diamond begins as small seeds, these seeds are placed in a sealed chamber, and with about 800 degrees Celsius it is heated up. It is filled with carbon gases ionized into plasma. This will cause the molecular bonds to break in the gas, and gradually the carbon will adhere to the diamond seeds and begins to crystalize.

Do the different methods of production affect the quality?

Not at all. The only difference between the diamonds is the method of production. It will interest to know that the lab diamonds after production have precisely the same Chemical compounds as the natural diamonds. If a lab diamond is placed side by side, a natural diamond, one cannot tell the difference because they are the same. The lab-grown diamonds are more advantageous.

Advantages of lab-grown diamonds

  • Less risk: the lab diamonds have as good as no risk in production when to the natural diamonds.
  • It is less expensive: lab diamonds are less expensive than natural diamonds. So one can get a bigger size of lab diamonds at a cheaper rate.
  • Nature friendly: the method of production of lab diamonds is nature friendly, unlike the natural diamonds that involves lots of waste and land disturbance.
