The first evidence of scientists creating synthetic diamonds goes as far back as the late 1800s to the 1920s. However, these first creations were analysed but not confirmed. In the 1940s, American, Swedish and Russian scientists began to formally grow lab-created diamonds using the processes of HPHT and CVD.
Around 1953 the first reported tiny crystals of synthetic diamonds were documented. Production of larger man-made diamonds for jewellery making and industrial purposes began in the mid-1990s.
