Chemically, optically, and physically identical, with a different origin story.
Read the guide →Lab-grown diamonds are grown in a lab using the same crystal structure and chemistry as mined ones. The same independent labs grade them on the same 4Cs: cut, colour, clarity, and carat. To your eye, they're the same stone.
