HPHT Diamonds

What is HPHT?

The term HPHT diamonds have been around since the 1950s, and their existence has been worthwhile. It’s a short form for High-Pressure High Temperature, and the name signifies the procedure of developing diamond inside a laboratory.One misconception that most people have about HPHT diamond is that they are synthetic diamonds.

However, synthetic diamonds are the ones that are purely fabricated inside a CVD diamond manufacturer’s laboratory from scratch. On the other hand, HPHT diamonds are not made from scratch. Instead, these are merely a finishing procedure for what the nature started once.

HPHT diamonds are extremely pocket-friendly, and you won't have to go bankrupt to flaunt a hefty ring in your finger, especially if you choose to buy from the best CVD diamond suppliers. Ever since this HPHT technique has entered the market, it has taken over the diamond industry like a storm.

HPHT diamonds are an inexpensive alternative to a super expensive mined diamond. You don't have to let go of your dream of owning a massive piece of the diamond; you just have to make the right choice of opting for HPHT diamonds from the most reputed CVD diamond suppliers. Much before CVD diamonds came into existence; the HPHT method was used to convert partially or incompletely crystallized diamonds into a fully crystallized diamond. It is a process of finishing what nature started millions of years ago by completing the crystallization of these ‘premature diamonds.'

Gone are the times when people were so high on pretending for social status that they could even go bankrupt for it. Now people are very well aware of their financial conditions and make decisions accordingly. However, this is also a fact that no matter how reasonable a woman is, her desire to own a shining piece of a diamond cannot be subsided.

If you wish to make that special woman in your life happy and make her feel important, there’s no better gift than this precious stone that she can cherish for life. Lab-grown diamonds are gaining immense popularity, and it is all because of their remarkable properties and highly affordable prices when purchased from the best lab-grown diamond suppliers.

Lab-grown diamonds have truly taken the diamond industry by storm ever since it was introduced. It did take a while for people to realize how practical and economical this alternative is, but now that people have realized, it has been an excellent path for these synthetic diamonds.

  • The name of this reaction gives away the significance of this procedure. HPHT diamonds are fabricated under controlled High Pressure and High Temperatures. The process starts with careful positioning of the partially crystallized diamond obtained while mining the earth. It is placed in a containment cube which is ideally surrounded from all the sides with heating pads to regulate the temperature. This technique should preferably be done by a professional gemologist in a CVD diamond manufacturers’ laboratory to ensure good quality and minimal mistakes.


    The next step is to set the temperature right. Diamond is subjected to a soaring temperature of 2,600 degrees of Celsius just as it is below the earth's crust. HPHT is all about creating an atmosphere just like in the crust and complete the work that the nature started but was interrupted for some reason.

    Next step is to replicate the force of pressure applied by the earth on the diamond when it is being made in the earth's crust. When the ideal amount of pressure is created inside the cube of containment, a diamond can achieve its full crystalline state, which is clear, white, and sparkly to look at.


    Facts and myths about HPHT diamonds:

    Unlike CVD diamonds, where the entire mass is made inside the laboratory of a CVD diamond supplier, HPHT diamonds are made with the help of raw or immature naturally occurring diamonds. When the nature starts making a diamond under the earth's crust, there can be many reasons why this process is interrupted like a volcanic eruption or a shift in the tectonic plates.

    The half made or partially crystallized diamonds can achieve their fully grown and sparkling stage with the help of HPHT technique. As clarified before, just because HPHT diamonds come to a lab for final touch-ups does not make them synthetic diamonds. This process simply completes the task that nature intended to do.


    It’s a cost-ineffective alternative to colored diamonds:

    Finding naturally occurring colored diamonds is an extremely rare event, and whatever colored diamonds are found to have their prices reaching for the sky. In this situation, a common man with desires of owning a colored piece of diamond is left hopeless.

    There’s a huge demand for colored sparkling stones, and the supply of these is very limited. This is the kind of situation that demands you to turn to HPHT diamonds. These diamonds are better quality, and an inexpensive variant of colored naturally occurring diamonds and one can easily afford these gemstones.
