(IDEX Online) - India will lead demand for natural diamonds in 2024, says David Kellie, CEO of Natural Diamond Council (NDC), as US buyers increasingly switch to lab growns."The Indian market remains the strongest growth market in the world because of its strong financial position and changing demographics," he told The Economic Times, in India."Indian women are now financially stronger, and they are driving the demand. The key economic indicators in the US are not yet favourable for a demand recovery in diamond purchase."Kellie (pictured) predicts a polarization between the natural and lab grown markets, with a price difference currently at 80 per cent to 90 per cent.Natural diamonds will become increasingly rare, he said, with no new mines in prospect, and with miners digging deeper, and spending more, to reach remaining deposits.
