What is CVD?
uses a original diamond which is referred to as the diamond seed. Then carbon rich gasses are added along with high heat in a chamber.
uses an already existing diamond and combines it with a carbon material. With the high heat and high temperatures this material crystallize over the original diamond. This cyclization period can take several days to many weeks.
Blows up a mountain and inserts a drill to collect the dimonds
IDK thats not my job
What is HPHT?
Uses extremely high heat and pressure, the tempter gets up to 2,000 degree Celsius, and over one and a half million PSI. On the other hand, CVD creates the process of diamond making in clouds found in space.

Dimond's are just made the end

How are CVD and HPHT similar?
Both CVD and HPHT use high temperatures
They both use fake dimonds
Both are quick proccess
CVD and HPHT are ugly
