Lab Grown HPHT CVD  Diamonds Description


CVD is an acronym for chemical vapour deposition and HPHT is an acronym of High Pressure High Temperature.Laboratory diamonds are generally produced by chemical vapor deposition (CVD) or high pressure and high temperature (HPHT) processes and are of similar quality to natural diamonds. 

Laboratory diamond is generally produced by chemical vapor deposition (CVD) or high pressure and high temperature (HPHT), and its quality is similar to that of natural diamond. Artificial diamonds are often used to process priceless jewelry because they can be cut into various shapes and polished to achieve many different surface treatments.

Artificial diamond has received a lot of attention in the past decade because it allows many new applications of diamond, which was previously considered too difficult. Artificial diamond is an environment-friendly product with no pollution technology and no environmental pollution.

Method of high temperature and high pressure (HTHP) with graphite as raw materials, the introduction of appropriate metal catalysts, such as Fe, Co, Ni, Mn, Cr, etc., can be in more than 2000 k and tens of thousands of synthetic diamond atmosphere temperature.

Chemical vapor deposition (CVD) is the raw material at high temperature decomposition, produce the active particles, such as carbon atoms or methyl and under certain technological conditions on the substrate (substrate) deposition of diamond film growth. Laboratory diamonds can be produced using HPHT and CVD technology through laboratory diamond forming machines. However, due to high temperature and high pressure, and chemical vapor deposition method to produce diamond use different machinery and technology, high temperature and high pressure and chemical vapor deposition method, the production of diamond can be apart from the production of diamond and laboratory.

In the lab, however, the production of gem grade diamond can now under natural conditions of production. The production of natural diamond can be used in the lab, high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) simulation technology in a few weeks.

Characteristics Of Lab Grown HPHT CVD Diamonds


Diamonds are grown in a laboratory. Advanced equipment is used to simulate the conditions in which natural diamonds are formed. Laboratory diamonds usually produce a few weeks in the lab. Natural diamonds are created by nature, is the result of the billions of years of high temperature and high pressure. The chemical differences between the two is the same.

So how to differentiate between diamond and natural diamond lab?

There is no significant difference between lab-grown diamonds and natural diamonds. Even professional gemologists also need special equipment to identify them. The growth of diamond and the subtle differences between the growth of the professional staff, can be amplified in the laboratory.

In the past decade, synthetic diamond has received wide attention because it allows many new applications of diamond. Lab-grown diamond is an environmentally friendly product with pollution-free technology and no environmental pollution.

From a scientific point of view, synthetic diamond and natural diamond are exactly the same. The only difference is that they are formed in different positions.
