Lab-grown diamonds are diamonds produced by scientists using technology that recreates the conditions under which diamonds form deep in the earth. A lab-grown diamond is chemically, physically, and optically identical to diamonds that formed naturally - the only factor that makes them different from a natural diamond is that they originate from a lab. For that reason, lab-grown diamonds cannot be considered ‘rare’ or ‘unique’ and as such they represent a more affordable option when compared to natural diamonds and are valued at a considerable lower price per carat.
