2 · CVD-processed stones are much different from the natural diamonds produced by geologic forces. They are also vastly different from the High Pressure, High Temperature (HPHT) synthetics that have been manufactured since the mid-1950s. CVD synthetic diamonds began appearing in the gem diamond market about a decade ago.
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 CVD diamonds but not HPHT ones and vice versa.
