How lab created diamonds are made
The answer to this question requires a deep explanation to really understand how a diamond is created in a laboratory. Two main procedures are commonly used to create lab-grown diamonds.
Besides the actual formation of the diamond, lab-grown diamonds are identical to natural diamonds in every way, only are created in a controlled environment using cutting-edge technology, rather than the depths of the earth. And, if you’re wondering 'do lab-grown diamonds pass a diamond tester?' They absolutely do! The same chemically, physically, and optically as mined diamonds, they will test positive using any diamond testing method.
In the first method, high pressure and high temperature (HPHT), the environmental aspects which are present in the earth's mantle where mined diamonds are created, are simulated. In the second technique, called CVD (or Chemical Vapor Deposition), a tiny diamond crystal "seed" is stimulated and grown into a diamond using superheated gas.Shop Lab Grown Diamonds
However, these explanations are pretty simple. There’s way more to them than that. So, let's talk about these procedures more in depth below:
Pressure-High Temperature method (HPHT)
The High Pressure High Temperature (HPHT) diamond production process was first developed in the 1950s for industrial use. As was already noted, mined diamonds can also be treated using the HPHT procedure to improve their overall clarity and color.
How are HPHT diamonds made?
The procedure was created to closely resemble the temperature and pressures of the earth's interior, where natural diamond crystals develop over the course of millions of years. In contrast to the roughly 150 million years it took for the world's natural diamonds to form, the HPHT technique successfully recreates this environment and enables a diamond to form in a matter of weeks!
Mined diamonds are formed miles below the surface of the Earth at temperatures and pressures well over 2,000 degrees Celsius. Around the same circumstances are required for the creation of an HPHT diamond (High Pressure High Temperature).
HPHT diamonds are produced using three fundamental manufacturing techniques: the split beer (BARS) press, the cubic press, and the belt press. A little diamond enclosed in carbon is placed into each process's high pressure and temperature environment for several days until a full-sized diamond is created.
Chemical Vapor Deposition (CVD)
A CVD diamond is created from a hydrocarbon gas mixture using a recently developed technology called chemical vapor deposition (CVD), which is similar to how diamonds arise in interstellar gas clouds. The CVD procedure, which was developed in the 1980s, is widely seen to be the less expensive way to make diamonds out of the two because it uses less energy.
How are CVD Diamonds made?
A small slice of diamond seed is heated to a temperature of around 800 degrees Celsius in a sealed container before being filled with other carbon-rich gasses, such as methane.
Microwaves, lasers, and other devices are used to ionize the gasses and create plasma. The breakdown of the gasses by ionization makes it possible for the carbon to merge with the diamond seed and grow the diamond layer by layer.Shop CVD Diamonds
FAQs - Frequently Asked Questions
Yes! A "synthetic diamond" is sometimes used to describe a lab-grown diamond. This term is somewhat misleading, though, as lab-grown diamonds have the same chemical and physical makeup as naturally occurring diamonds, and as a result, the only way to tell their difference is by the method used to produce them.
The truth is that all the physical, chemical, optical, and atomic properties are identical to those of a naturally mined one. The difference is that some diamonds are mined, and some are lab grown diamonds – being both real diamonds.
The first advantage of lab-grown diamonds is that mined diamonds and lab-created diamonds cannot be distinguished from one another. The untrained eye cannot tell whether you are wearing a man-made or mineral diamond. In addition to their stunning appearance, lab-created diamonds are environmentally friendly because they do not harm any land.
Man-made diamonds are not only a better option for the environment, but they are also a better option for your wallet because they are 50% less expensive than minerals with the same appearance.
It also means that you can get twice the size of the diamond for the same price, making them wonderful pieces for you and future generations!
The answer is also yes! The thermal and electrical conductivity of laboratory-grown diamonds is identical to that of mined diamonds. They will consequently ace the diamond tester test.
