An Overview of Lab-Grown Diamond Manufacturing Processes
Natural diamonds form deep underground, about 177 to 241 km below the surface. Pressures at this depth can reach nearly 50,000 atm. (One atmosphere, or “atm,” is similar to the air pressure at sea-level). Temperatures will vary from 900º to 1,300º C. These intense conditions compress carbon into its most compact type, making diamonds in …
