As natural diamond prices go up, more people are choosing lab-made diamonds, which cost 70–90% less.
“The difference in price is the reason why demand for lab-grown diamonds is on the rise. However, the income from these diamonds is decreasing,” said Dinesh Navadiya, former president of the Surat Diamond Dealers Association.
The jewellery made with lab-grown diamonds can be sold just like conventional jewellery, as these diamonds also come with a certificate.
Rising gold prices have also turned jewellery consumers towards lab-grown diamonds. The rising prices of imitation jewellery are also a factor in a boost in the lab-grown diamond business.
In Surat, 15-17 large units manufacture lab-grown diamonds. However, the new players may find it hard to survive in the business due to low margins, experts believe.
Lab-grown diamond exports are rising to countries like the US, Hong Kong, Bangkok, the UAE, and the EU.
