According to a report by CNBC TV-18, the International Gemmological Institute (IGI) witnessed a 27 percent jump in certification volumes for lab-grown diamonds over the past years.

While the concerns over lower margin looms, IGI is confident that the volume growth will offset any potential margin pressure.
Eashwar Iyer, the Chief Financial Officer at IGI told CNBC TV18 that the current margins of lab-grown diamonds are between 56 and 57 percent and exuded confidence that there’s no downside risk because increasing volumes will compensate for the margin differential.
The US has been the largest market for lab-grown diamonds, but India is emerging as a significant player.
“Earlier, only 1.5 percent of the world’s population purchased diamonds. However, with the greater accessibility of the lab-grown diamonds, the percentage of buyers is expected to rise to 5-10 percent,” Tehmasp Printer, Managing Director and CEO of IGI India.
The certification of diamonds has also expanded from smaller stones to larger stones, typically in the 1.5-2 carat range, with some reaching as high as 10-20 carats.
