Synthetic diamonds
The phrase “Diamonds are merely unremarkable carbon” highlights the essential truth that both diamonds and graphite are made of pure carbon, but in different forms, or allotropes. This discovery led to the continued pursuit of methods to artificially create diamonds. After 157 years of research, scientists found that a key factor in transforming carbon into diamonds is the use of catalysts, also known as chemical agents, to accelerate the process.
