HPHT stands for High Pressure High Temperature. It is a process by which diamonds are created in a lab. HPHT diamonds are diamonds that have been created using a process that mimics the conditions found deep within the Earth’s mantle, where natural diamonds are formed over millions of years.
In the HPHT process, a small diamond seed is placed in a press and it is subjected to high pressure. The pressure in the press is around 5 to 6 gigapascals. The temperature of the press goes upto 1,500 to 1,600 degrees celsius. Due to these extreme conditions, carbon atoms get rearranged and form a crystal lattice. This then grows into a diamond over time. This process typically takes several weeks to create a perfect diamond.
The HPHT process is able to replicate the natural diamond growth process by mimicking the heat and pressure that occurs in the Earth’s mantle. The lab grown diamond that has been created by the HPHT process have the same physical, chemical, and optical properties as natural diamonds. These diamonds are composed of pure carbon and exhibit the same hardness, brilliance, and durability as diamonds mined from the Earth.
HPHT diamonds have gained a lot of popularity in the recent years due to the advancements in the diamond creating technology. These HPHT diamonds are an ethical and environmentally friendly alternative to mined diamond and they creat a very small carbon footprint than mined diamonds. These diamonds are also quite affordable than natural diamonds. It makes them an attractive option for consumers that are looking for a high quality and high end diamond jewelry at a lower price point. When it comes to CVD vs HPHT diamonds, there is a tie as both these methods create superior diamonds.
Benefits of HPHT Diamonds
There are several benefits of lab grown HPHT diamonds. They are as following:
Ethical and Environmentally Friendly
Since lab grown diamonds are created in a lab, it eliminates the need for mining. Mining has detrimental effects on the environment. It includes habitat destruction, soil erosion, and water pollution. By choosing lab grown diamonds, you can make sure that you are choosing the safety of he nature. It is a sustainable choice.
Conflict Free Diamonds
Lab grown diamonds are conflict free due to the fact that they are created in a lab and ar not mined from the Earth. It means that they are not associated with any human rights abuses or conflicts. Natural diamonds on the other hand can be associated with conflicts in certain regions of the world. Thus, lab grown diamonds are a better alternative.
High Quality Diamonds
Lab grown diamonds feature the same physical and chemical properties as natural diamonds. They have the same level of hardness, brilliance, and durability. It makes them a high quality alternative to mined diamonds. And since they are created in a lab, there is a quality control. It means that lab diamonds are of superior quality.
Wide Range of Options
Lab grown diamond offer a wide range of options. These diamonds can come in various sizes, shapes, and even colors. Even fancy diamonds can be created in a lab. This allows the consumers to find the perfect diamond that suits their preference and styles.
Cost Effective Method
Lab grown diamonds are indeed more affordable than mined diamonds. The cost of mining and extracting natural diamonds contributes to their high prices. Lab-grown diamonds are created in a lab and thus they come at a lower price point.
Lab grown diamonds are not subject to the limitations of natural diamond availability. They can be created as per the need and are technically limitless. On the other hand, natural diamonds are finite resources, and the supply is becoming increasingly scarce. Thus, lab grown diamonds offer a consistent and reliable supply.
