HPHT Diamond: Everything You Need To Know

Know About HPHT Diamonds Finegrown Diamonds

HPHT diamond (high pressure and high temperature) is made over in lab and the process was developed by the De Beers company to create diamonds that are more valuable than those created through traditional mining methods. The process involves heating a mixture of carbon, hydrogen, nitrogen, oxygen, and other elements at extremely high pressures for several hours or days until it becomes liquid metal. This causes the atoms within the material to rearrange themselves into new structures which can be used as gemstones. These gems have been known since ancient times but were not widely produced until recently due to their rarity and cost. Today they are commonly found in jewelry stores around the world.

Diamonds were originally formed deep underground where temperatures reached up to 2200 degrees Fahrenheit. As time went by, scientists began looking at ways to create synthetic diamonds using different methods. One method involved heating graphite ore until it turned into carbon and made from carbon source. Another way was to heat silicon carbide which would then turn into quartz. Both of these materials could not produce diamonds though. 

Future of HPHT Diamonds

The future of HPHT diamonds looks bright with many companies working on creating better technology to make them even stronger and cheaper. There are also plans to use this technique to create artificial diamonds from non-diamond starting materials such as coal tar and oil shale. It will take some time before we see any real results because there are still so many things to learn about how to control the reaction properly. However, if all goes well, we may soon find ourselves wearing our own custom designed engagement rings!

The HPHT process is the most common method of diamond production. It involves heating a mixture of carbon and metal to extremely high temperatures, which causes them to react with each other in various ways. The resulting product contains many different types of diamonds that are all formed at roughly the same time. This means they have similar characteristics such as color, clarity, hardness, etc., but can be differentiated by their size or shape.

Benefits Of Using HPHT Diamonds In Fine Jewelry

HPHT diamonds are preferred to used in fine jewellery along with various types of metals like gold, platinum’s, silver etc. HPHT diamonds are available easily with wholesale price also got certified of diamonds clarity, purity with this reason jewellery manufacture relay over it and used in jewellery to built ornaments. 

Reasonable Price:

HPHT diamonds are comes in affordable price rather than natural one stone. Natural diamonds go expansive due to their long process mining, supply chain and middle commissions etc. And this HPHT diamonds comes to your direct from lab, that is one of a reason you can go with HPHT

Certified Diamonds:

This lab grown diamonds (HPHT diamond) are comes with certification from the genuine quality checking labs GIA, CGI etc. when you purchased with that certification also comes. 


Natural diamonds are damage the minerals, lands and forest as well due to lots of cutting trees, blast for mining there are earth damage that can directly effect to climate change. This lab grown HPHT diamond are completely environment friendly.

HPHT Process In Lab

In the laboratory, the raw materials are heated up to very high temperature under pressure to form new compounds called carbides. These carbide crystals grow into tiny grains of pure diamond. When these small grains become large enough, they’re separated out and polished until they shine bright white.

How Does A HPHT Diamond Differ From Other Types?

A traditional “natural” diamond has been mined from its parent rock using explosives and heavy machinery. And HPHT and CVD diamonds are made in a Lab process under the human observations. 

What Is High Pressure High Temperature (HPHT) Color Treatment?

Natural diamonds are comes with white colors but in lab grown diamonds there are possibly way to process color based like yellow diamond, blue diamond, pink diamond and other, Diamonds colors ranging from D to H consider you can check it our diamond color range page. 

HPHT process is all time fixed and you do not worried about to maintain lab grown based diamond color and shining.

What is the difference between HPHT diamonds and CVD diamonds?

There are major different in HPT diamond and CVD diamonds is just to growing process or for their morphologies techniques used. HPHT diamonds grow in cuboctahedron shape and have 14 growth directions, while CVD diamonds grow cubic and have 1 growth direction, while CVD diamonds grow cubic and have 1 growth direction.

HPHT diamonds and CVD diamonds

If you are compare with these lab grown diamonds with natural one then you can see natural diamonds comes in octahedron shape and only have 8 growth directions. 

And in lab grown diamonds HPHT and CVD both have used different techniques to grow HPHT has comes with more yellowish and brownish types of diamonds developed and with CVD diamonds is developed colorless one. But current time both technologies implement to developed diamonds like colorless and flow less diamonds, and there minor difference happen rather this morphology technique. 

It’s worth noting that there’s a lot of conflicting information about which method of diamond growth is preferable. Behind the scenes, though, each corporation is attempting to push what benefits them the best. Customers will be advised to avoid HPHT diamonds by a CVD business, and vice versa.
