New Man Made Diamond Creation Technologies

Science has developed new machines that duplicate the volcanic heat and pressure required to change carbon into diamond as found imbedded in the walls of volcanoes. The volcanic pressure alone is equal to [40] tons on a piece of coal! The volcanic heat required is a minimum of [1500] degrees celsius.This man made diamond growth technology is called [HPHT]"Temperature Gradient Method."

The second man made diamond growth technology is called [CVD] "Chemical Vapor Deposition." It is similar to [HTHP] in which a high temperature of [1000] degrees celsius is required along with a low pressure system using hydrogen and methane gas.

The third man made diamond growth technology uses the "High Temperature-High Heat" process applied to a diamond crystal and sapphire composite which causes a fusion of the two precious gemstones. This is primarily used to create man made diamond simulants.

All three technologies are using diamond crystals to grow real man made diamonds or fusion of diamond crystals and sapphires to grow man made diamond simulants. The [CVD] process will produce the purest diamond with lowest inclusion or metalic trapped in the man made diamond. The [HPHT] growth environment is more volatile and works better with "Fusion Technology" that requires higher temperature and heat to join compatible bonding forces together into a new molecular design configuration. The process is used to grow man made diamond simulants.

These technologies have grown and advanced over the years. The most advanced [CVD] "Chemical Vapor Deposition" process produced the "Apollo Diamond" in [2003] and the most advanced [HTHP] "High Temperature-High Heat" fusion process produced the "Israel Hybrid Diamond Simulant in [2004]. Moreover; [HTHP] diamond creation environment has resulted in higher metalic inclusion rate trapped inside elongated diamond crystalline structure compared to the newer inclusion free [CVD] technology.

All three man made diamond growth technologies produce either exact molecular duplicates of real diamonds or man made diamond simulants with all the natural qualities of real diamonds. The diamonds are still a little harder and less dense than the simulants. But world wide technology is being shared by European, American and Israel scientist who are working on a second generation of man made diamond simulants that share the same mineral properties with natural diamonds.
