How lab created diamonds are grown

You must have bought consumable goods before, and just at the side of the pack or nylon, you will see the ingredients on what was used in making it. You also must have watched some Do it yourself (DIY) videos on how to make some products of your choice either consumable or not.

 

Okay, this may not be an in-depth detail on how lab-created diamonds are grown or how lab-created diamonds are made, but it gives a brief overview of the creation process of lab-created diamonds split into three stages. When lab-created diamonds were first birthed, it was used mainly for industrial purposes, and this is the first stage of its creation we would discuss.

 

During the late 1980’s it was then commercialized and available for sale to the public, its creation process must have been tweaked a little to make it efficient and effective for commercial purposes, and this will form the second part of its creation that will be discussed. The last phase is its creation in this modern time when it has been modernized, and the quality was improved in terms of the popular 4C’s which are its color, carat quality, cut and quality, this will form the third part of its creation process.

 

How were lab-created diamonds previously grown?

Henry Moissan, one of the pioneers of the creation of the synthetic diamonds, claimed he effectively made a diamond by heating charcoal toa temperature as high as 3500 °C in a carbon crucible.

 

However, several people tried replicating this process used by Henry Moissan but didn’t get verification from the authorization labs. Over a while, other diamond producers tried to create diamonds like other gemstones, but they utterly failed in their bid until manufacturers had the thoughts about the possibility of creating diamonds in the lab rather than how they previously tried replicating diamonds with the same method used for replicating gemstones.

 

It was these lab processes that the manufacturers finetuned, which ensured they made not only synthetic diamonds but also made high-quality diamonds; these lab-created diamonds overtime were refined to produce rings and other jewelry while H. Tracey Hall also developed the bell press with the synthetic diamond. The belt press was used to create high temperatures and pressure, which were able to melt metals like nickel, iron, and cobalt to change them to diamonds.

 

How has the lab diamond creation change through the years?

Through decades, several individuals professed to have successfully manufactured diamonds, but until not so long ago, there was no recorded, reproducible method for replication. The first success at creating diamonds was recorded by replicating nature with the high pressure and high-temperature technique (HPHT).

 

From that point forward, different strategies have been employed like the belt press, chemical vapor deposition (CVD), present-day cubic, and split-circle presses. These techniques were bigger and progressively proficient in creating synthetic diamonds.

 

The present creation process of the lab-created diamonds

There is global research into the chemical vapor deposition (CVD) method. With the everyday improvement in technology, it is expected that the size and quality of diamonds created with the high pressure and high-temperature technique (HPHT) should equal the diamonds created by the chemical vapor deposition (CVD) method.

 

Although research is still ongoing to make these methods produce diamonds of better quality, and this research has been producing great results according to reports. These methods have been able to produce diamonds that can be affordable and lab-grown diamonds that be cut into various sizes and shapes.

 

The creation process of an HPHT diamond begins by placing a small diamond seed in carbon, and this seed is then heated to about a degree of 1500 °C and exposed to a pressure as high as 1.5 million pounds per square inch. When the carbon begins to melt, it begins to form around the diamond seed, after which it is cooled and solidified, bringing about a pure diamond.

 

The CVD diamond, on the other hand, can use an HPHT diamond as its base diamond seed. It involves the use of a growth chamber, a plasma ball, much heat around 800°C, and ionizing the gasses into plasma using the methodology similar to that of lasers. The diamond seed while placing it in a chamber for a period of 3 to 4 weeks and then cutting and polishing the rough diamonds.
