Hao to make diamonds?

Question

whats the best way to do it?

Answer 1

1. "positioning tiny particles onto a silicon template containing precisely spaced holes that are about one-hundredth the width of a human hair. The template is immersed in water on top of which particles are floating, and the particles automatically fill in the holes as the template is lifted."

2. "Researchers at the Carnegie Institution’s Geophysical Laboratory have learned to produce 10-carat, half-inch thick single-crystal diamonds at rapid growth rates (100 micrometers per hour) using a chemical vapor deposition (CVD) process. This size is approximately five times that of commercially available diamonds produced by the standard high-pressure/high-temperature (HPHT) method and other CVD techniques"

3."device starts with a carbon source and a shard of a real diamond called a "seed." The machine squeezes the seed with increasingly higher pressure topping out at 850,000 pounds per square inch. Other equipment heats the core to 2,000 to 3,000 degrees Fahrenheit. The high pressure and high temperatures transform the seed into a bigger diamond. "

4. "subjected the tough CVD crystals to high-temperature and high-pressure conditions. The diamonds were heated to 2000° C and put under pressures between 50,000 and 70,000 times atmospheric pressure (5-7 GPa) for ten minutes. This final process resulted in the ultrahard material, which was at least 50% harder than the conventional diamonds"

Answer 2

Take carbon and smash and heat it up.

Answer 3

tons of pressure, you cant do it
