Lab-grown diamonds have existed since the 1950s, though early versions were limited to industrial use due to their lower quality. It’s only within the last decade that scientists have perfected the process of growing gem-quality diamonds. Using advanced technology, these diamonds are formed under carefully controlled conditions that replicate the intense heat and pressure found deep within the Earth’s mantle.
Just like natural diamonds, lab-grown diamonds are made entirely of carbon atoms arranged in the classic diamond crystal structure. The result is a stone that is chemically, physically and optically identical to a mined diamond.
