Creating sparkle and fire is the main objective of any diamond. Whether you are looking to buy or sell a diamond, the right characteristics are what will drive its value and get you the highest offer. If your priority is clarity over cost, then high-pressure high-temperature (HPHT) diamonds might be perfect for you. As the name suggests, these diamonds are mined at high pressure and extremely high temperatures in order to bring out their hidden beauty. In this article, we will help you understand how CVD vs HPHT diamonds compare in terms of their properties, advantages, and disadvantages.

What is a HPHT Diamond?
HPHT diamonds are created by subjecting naturally occurring graphite to extreme heat and pressure to turn it into diamonds. This process was developed in the year 2000 and has made inroads in the jewelry industry due to its lower quality diamonds.
What is a CVD Diamond?
CVD diamonds are created through a process called chemical vapor deposition. During this process, diamond crystals are grown on a substrate in a controlled environment where carbon is deposited. CVD is one of the newest ways to create diamonds and has made major inroads in the jewelry industry. Since the process is done in a controlled environment, CVD diamonds are able to meet the grading scale.
Comparing CVD vs HPHT Diamonds
The main difference between CVD vs HPHT diamonds is how they are made. We have already discussed the HPHT process, now let’s move on to discuss the CVD process. CVD is a process in which carbon is deposited on a substrate to create diamonds. The substrates can be either metal or ceramic, but they should be completely non-reactive. The diamonds are grown in a controlled environment and are very similar to HPHT diamonds. CVD diamonds are created through a process known as chemical vapor deposition. The process involves growing diamond crystals in a controlled environment where carbon is deposited on a substrate. The diamonds created through the HPHT process are lower quality and do not meet the grading scale like CVD diamonds do. CVD diamonds have the same qualities as natural diamonds, so they are more expensive. HPHT diamonds are lower quality, less expensive, and do not meet the grading scale. HPHT diamonds are created from carbon that is deposited on a substrate. The process is done in a controlled environment and is one of the newest ways to create diamonds. Since this process is done in a controlled environment, HPHT diamonds are able to meet the grading scale.
