Last accessed: 31.08.2026
Supports that large, high-quality diamonds are rare, that diamond mining can be expensive, and that quality and rarity influence value.
“Most mining for diamonds is expensive because of the tremendous volume of ore that must be removed and then processed”

Supports the four diamond quality factors Clarity, Color, Cut and Carat Weight and the relationship between rarity and value.
“The value of a finished diamond is based on this combination.”
“Value and rarity are related”

3. How Are Diamonds Grown in a Laboratory?
Q5 – GIA – HPHT and CVD Diamond Growth Processes: Making Lab-Grown Diamonds
https://www.gia.edu/gia-website/hpht-and-cvd-diamond-growth-processes
Last accessed: 31.08.2026
Supports the two important laboratory diamond growth methods HPHT and CVD. In HPHT, carbon material and a diamond seed are subjected to very high pressures and temperatures. In CVD, a diamond seed is placed in a chamber containing a carbon-rich gas.
“synthetic diamonds are produced from carbon material in apparatuses that mimic the high pressure, high temperature conditions”
“Diamonds grow from a hydrocarbon gas mixture”

Last accessed: 31.08.2026
Supports the use of HPHT and CVD as the two diamond growth processes and describes their technical foundations.
“This overview summarizes the two diamond growth processes: high-pressure, high-temperature (HPHT) and chemical vapor deposition (CVD).”
