The story of lab-grown diamonds is a testament to decades of innovation and scientific progress. The journey began in 1956, when General Electric created the first HPHT (high pressure, high temperature) diamonds by replicating the natural conditions deep within the earth. Although a patent for CVD (chemical vapor deposition) technology was filed in 1954, it wasn’t until the late 1980s that scientists were able to reliably produce diamonds through the CVD process.

 

Over time, CVD technology has been refined around the world—most notably in India, where the method has reached exceptional levels of precision and consistency. In this process, crystallized carbon is introduced into a hydrogen-rich environment, then energized with microwaves to form high-quality diamond crystals. These rough CVD diamonds serve as the foundation for the sustainably grown stones used today.

 

Early CVD machines could nurture only a single “diamond seed” at a time. Thanks to global collaboration and tireless innovation, modern facilities can now grow multiple diamonds simultaneously with remarkable efficiency. Companies like Harding Quality continue to benefit from these advancements, partnering with expert growers across India and beyond to source ethically produced, beautifully crafted lab-grown diamonds.

 

Harding Quality proudly supports a network of trusted partners across Mumbai, New York, Europe, Hong Kong, and Dubai, ensuring access to consistent quality and responsible production practices.
