The concept of creating artificially dates back to the 19th century. Scientists and inventors were intrigued by the idea of replicating nature's process of diamond formation. They understood that diamonds were essentially crystallized carbon formed under immense pressure and heat over millions of years. The challenge was to recreate these extreme conditions in a controlled environment.

Early Attempts

In the 1940s and 1950s, several research groups began serious attempts to create diamonds in the laboratory. The most notable efforts were made by General Electric (GE), the Swedish electrical company ASEA, and scientists in the Soviet Union. These attempts were driven by both scientific curiosity and the potential industrial applications of synthetic diamonds.

The Breakthrough

The first confirmed successful synthesis of diamond was achieved by GE in December 1954. The team, led by Tracy Hall, used a belt press apparatus to subject graphite to extreme pressure and temperature. This breakthrough marked the birth of lab-grown diamonds and opened up a new field of research and technological development.

Two Primary Methods

As research progressed, two main methods for growing diamonds in the laboratory emerged:

1. High Pressure High Temperature (HPHT) : This method mimics the natural formation process of diamonds by subjecting carbon to extreme pressure and temperature.
2. Chemical Vapor Deposition (CVD) : Developed later, this method involves growing diamonds from a hydrocarbon gas mixture in a vacuum chamber.

Evolution and Refinement

Over the decades, these methods have been refined and improved. The quality, size, and color of lab-grown diamonds have steadily increased, making them virtually indistinguishable from natural diamonds to the naked eye.

The invention of lab diamond is not attributed to a single individual but rather to a collective effort of scientists and researchers over several decades. However, certain key figures stand out in the history of this revolutionary process.

Tracy Hall: The Breakthrough Inventor

The most prominent name associated with the invention of lab-grown diamonds is Howard Tracy Hall . Working for General Electric (GE) in the 1950s, Hall led the team that achieved the first reproducible synthesis of diamond on December 16, 1954.

Hall's Contribution

Hall designed a revolutionary apparatus called the "belt press," which could subject carbon to the extreme pressures and temperatures necessary for diamond formation. His success came after years of failed attempts by various researchers worldwide.

The GE Team

While Hall is often credited as the inventor, it's important to note that he was part of a larger team at GE working on the diamond project. Other notable contributors included:

• Herbert Strong : Project leader
• Francis Bundy : Researcher who made significant contributions to the understanding of the diamond-graphite equilibrium
• Robert Wentorf : Chemist who later developed the process for creating cubic boron nitride, another super-hard material

Earlier Attempts and Contributions

Before the GE breakthrough, several scientists made important contributions to the field:

Henri Moissan

In 1893, French chemist Henri Moissan attempted to create diamonds by heating charcoal to 3500°C in a carbon crucible with molten iron. While he didn't succeed in creating diamonds, his work laid important groundwork.

Percy Bridgman

American physicist Percy Bridgman developed high-pressure apparatus in the early 20th century that was crucial for later diamond synthesis experiments. His work earned him the 1946 Nobel Prize in Physics.

Soviet Contributions

Parallel to the work at GE, scientists in the Soviet Union were also working on diamond synthesis. In February 1956, Boris Deryagin and Boris Spitsyn announced their success in growing a diamond on a seed crystal, though details of their process were not widely shared at the time.

Inventors of CVD Method

While the High Pressure High Temperature (HPHT) method was the first successful approach, the Chemical Vapor Deposition (CVD) method was developed later:

• William G. Eversole of Union Carbide reportedly first achieved diamond growth by CVD in 1952, though his results were not widely reproduced at the time.
• In the 1980s, researchers at the National Institute for Research in Inorganic Materials (NIRIM) in Japan, including Satoshi Matsumoto , made significant advancements in CVD diamond growth.

Ongoing Innovation

The invention of lab-grown diamonds didn't stop with these early pioneers. Numerous scientists and engineers have contributed to refining and improving the processes over the years:

• Robert Linares founded Apollo Diamond in the 1990s and made significant improvements to the CVD process.
• Russell Hemley and his team at the Carnegie Institution for Science have pushed the boundaries of diamond synthesis, creating large, gem-quality diamonds.

The invention of lab-grown diamonds is a testament to collaborative scientific effort and persistence.

The Definitive Moment: December 16, 1954

The first conclusively documented and reproducible synthesis of diamond occurred on December 16, 1954 . This groundbreaking achievement was accomplished by a team of researchers at General Electric (GE) led by physicist Howard Tracy Hall.

The GE Breakthrough

Hall and his colleagues used a device called a belt press, which subjected carbon to extreme pressures of more than 100,000 atmospheres and temperatures exceeding 2000°C. This process, known as High Pressure High Temperature (HPHT), successfully replicated the conditions under which natural diamonds form deep within the Earth.

Earlier Claims and Attempts

While the GE achievement in 1954 is widely recognized as the first successful and verifiable production of lab-grown diamonds, there were earlier claims and attempts:

1879: James Ballantyne Hannay

Scottish chemist James Ballantyne Hannay claimed to have produced diamonds by heating a mixture of paraffin, bone oil, and lithium in sealed wrought-iron tubes. However, later analysis of his samples suggested they were likely natural diamonds.

1893: Henri Moissan

French chemist Henri Moissan attempted to create diamonds by heating charcoal to extremely high temperatures in a carbon crucible with molten iron. While he claimed success, his results could not be replicated, and it's now believed he produced silicon carbide, not diamond.

1920s: Dr. Willard Hershey

Dr. Willard Hershey of McPherson College reportedly produced small synthetic diamonds, but his work was not widely recognized or replicated at the time.

Parallel Developments

Around the same time as the GE breakthrough, scientists in other parts of the world were also making progress:
