Lab-grown diamonds — also known as man-made, engineered, or cultured diamonds — are real diamonds created in controlled laboratory environments using cutting-edge technology that replicates the natural diamond-growing process.

Just like mined diamonds, lab-grown diamonds are made of pure crystallized carbon, with the same chemical, physical, and optical properties. The only difference is their origin — one grows underground over billions of years, and the other grows in a lab over a few weeks.
