How Are Manufactured Diamonds Created?

1. How Are Manufactured Diamonds Created? The journey off an HPTP diamond starts as a small diamond seed put into carbon. This is exposed to temperatures as high as 1500 degrees Celsius and pressure of 1.5 million pounds per square inch. This leads to the melting of the pure carbon and formation of a diamond around the starter seed. The temperature needs to be brought down and it is then carefully cooled. The outcome of this process is a pure carbon diamond. To wrap our heads around the formation of lab grown diamonds, first, it is essential to understand how natural diamonds come into existence. This is because lab grown diamond manufacturers replicate exactly this. Basically, they have created the conditions found inside the Earth, on its surface. It is believed that mined diamonds were formed approximately 1 billion to 3 billion years ago, deep inside the Earth. The exact process is unknown but it is known that the journey begins from the carbon dioxide which is buried around 100 miles beneath the Earth’s surface. This gas is exposed to extreme conditions of heat and pressure. 2,200 degrees Fahrenheit pf heat and 727,000 pounds of pressure per square inch is what is needed to convert Carbon dioxide to a diamond. These diamonds are then pushed upwards to the Earth’s crust from its core by volcanic explosions. What is a CVD diamond then? This starts with a thin slice of a HPHT diamond seed. This is exposed to about 800 degrees Celsius of heat inside a sealed chamber. This chamber is full of gases like Methane that are rich in carbon. Technology similar to that in microwaves and lasers is used to ionize these into plasma. This process breaks down the molecular bonds of the gases and the pure carbon sticks to the diamond seed and crystallizes. We’ve all heard that diamonds are a girl’s best friend and maybe it was true. It was true until the cruelties associated with mined diamonds surfaced (literally). From then on there are several types of people who have stopped buying and selling these. The first type is the one that truly cares about the environment and human life. These people do not want to have anything that contributes to environmental harm and loss of life. The next type consists of those who are known to jump on the bandwagon. This bunch is only staying away from diamonds cause that is what is “in vogue”. The next is the seller who sees no point in dealing with mined diamonds and the demand has dropped drastically. So what is the way out? Manufactured diamonds is your answer.

2. There are three manufacturing processes that create extreme pressure and temperature conditions by which HPHT diamonds come into being. They are a belt press, a cubic press and the split-sphere (BARS) press. These are created in laboratories of lab grown diamond manufacturers. One common myth that comes along with lab grown diamonds is that they’re synthetic and fake. Truth be told, they’re only as real as the diamonds you mine from the Earth. This article takes you through how humans were able to replicate something that nature takes millions of years to form, so closely. Read on to understand how manufactured diamonds come into being, in a controlled space and how quick the process is. Lab grown diamonds are more or less created in the same way. There are two processes that lab grown diamond manufacturers use namely, - High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These were the two processes that cause much lesser environmental damage than mining of natural diamonds. What’s better is that the diamonds created using these technologies are as real as their natural counterparts.
