Did you know that diamonds are not all created equal? Certain diamonds are manufactured through special processes known as CVD and HPHT. In this post, we are going to read about the contrasts in CVD diamonds and HPHT diamonds and about how they are made.
CVD vs HPHT
CVD and HPHT are two different methods used to make diamonds. CVD stands for Chemical Vapor Deposition, HPHT for High Pressure High Temperature. Both approaches employ unusual carbon-converting processes to yield diamonds right here on Earth.
Comparing CVD and HPHT
One key difference between CVD and HPHT diamonds is how they are generated. CVD diamonds are built up in layers using a particular gas. HPHT diamonds are produced by subjecting carbon to high pressure and high temperature. Another distinction is how long it takes to produce each type of diamond. CVD diamonds are produced more quickly than HPHT diamonds.
Understanding the Differences
What to know about how CVD and HPHT diamonds are createdIn order to better comprehend how CVD and HPHT diamonds are formed, it is necessary to first to take a look at the way in which they are produced. CVD diamonds are produced by heating a gas, such as methane, until it decomposes into carbon atoms. This carbon adheres to a surface and eventually produces a layer of diamond. High pressure, high temperature diamonds are grown by introducing carbon to extreme pressure and heat to cause it to transform into a diamond.
The Chemistry of CVD and HPHT Diamonds
The science behind CVD and HPHT diamonds is fascinating. For CVD diamonds, a plasma ball is generated from a hot gas. That helps the carbon atoms connect and grow into a diamond. In the case of HPHT diamonds, the pressure and temperature are so high, the carbon atoms line up as a diamond form.
Pros and cons of CVD and HPHT diamonds
There are advantages and disadvantages to both CVD and HPHT diamonds. One of the nice things about them is they grow fast and grow big where natural diamonds even the most high CVD diamonds are quite different. But HPHT diamonds are also some of the best quality and purest diamonds found. The trade-off is that HPHT diamonds also take longer to produce, and they typically come in smaller sizes than CVD diamonds.
In summary Optical Grade CVD diamonds and HPHT diamonds both have their special characteristic and are produced by different methods. Whether you prefer a fast and formidable CVD diamond or a premium HPHT diamond, there are plenty to choose from. Diamonds are indeed forever gems and could be cherished forever.
