Lab-grown diamonds could account for a large share of global diamond supply – Petra

30 june 2023

Petra Diamonds says the supply of lab-grown and natural diamonds is expected to vary significantly in the coming years, with the former having the potential to become a significant part of the total global diamond supply.

It said in an update that factors strengthening lab-grown supply include production scaling by current producers, new producers, and breakthroughs in production technology that are improving yields and lowering production costs.

“Lab-grown demand is being driven by the lower relative pricing point as larger lab-grown diamonds are being sold at the same price as smaller natural diamonds,” said Petra.

The miner also said that lab-grown diamonds have continued to diverge into a separate, more affordable jewellery category

Meanwhile, Petra Diamonds said that the supply of natural diamonds is expected to remain relatively stable in the near term.
