LAB GROWN DIAMONDS – HPHT vs CVD. The first basic process to grow diamonds in a laboratory is called High Pressure High Temperature, also known as the HPHT process. Regardless of which machine configuration is used, be it one large piston or six pistons pressing together, a pressure of at least 700,000 pounds per square inch must be achieved ...
2017-8-1 · The suitability of type IIa diamonds prepared by High Pressure High Temperature (HPHT) in cubic presses at New Diamond Technology was assessed as substrates for the growth of thick detector-grade quality Chemically Vapour Deposited (CVD) diamond films. The substrates were found to possess a moderate dislocation density of about 10 3 cm − 2 and a reduced amount of residual impurities as ...

2020-7-6 · The majority of CVD single crystal diamond is available with {100} orientated surfaces, with {110} edges, while the {111} is the cleavage plane. All of these surfaces can be presented in CVD diamond engineered products. Polycrystalline diamond The grain structure of polycrystalline CVD diamond has a non-uniform composition, due to the growth ...

CVD diamond with strain lines: 2.16ct G VS1 CVD diamond with strain lines: 1.72ct G VS1. In contrast, HPHT diamonds do not exhibit such strain lines. Note how much clearer a diamond without strain lines looks compared to the CVD examples above. HPHT diamond without strain lines: 1.56ct E VS1

Both CVD or HPHT technologies can produce any colour, clarity, and size, from the unsellable to faultless diamonds. What is happening behind the scenes, is that each of their suppliers, the labs creating the diamonds, is giving them a better deal, and sometimes pressuring, on .
