Diamond market is changing

After shocking the market with a decision to start selling jewellery containing synthetic diamonds, Anglo American’s De Beers is planning to let buyers refuse some lower-quality stones.

The unusual move says lots about the state of the low-end diamond market. The last time De Beers did something similar, in fact, was two years ago, when India’s move to ban high-value currency notes pushed down demand.

Cheaper diamonds, which are often small and low quality, are selling for a lot less now than five years ago. And when it comes to synthetic stones, De Beers’ entry in the market will create a big price gap between mined and lab diamonds, pressuring rivals that specialize in synthesized stones at the same time.

A 1-carat man-made diamond sells for about $4,000 and a similar natural diamond fetches roughly $8,000. De Beers new lab diamonds will sell for about $800 a carat. That’s a fifth of the price of existing man-made stones and one-tenth of the cost of buying a similar natural gem.

No wonder competitors are worried. The lab-grown industry has filed a complaint with the U.S. Federal Trade Commission, accusing De Beers of price dumping and predatory pricing.

Based on the De Beer’s own analysis, consumer demand for diamond jewellery in the US — where its Lightbox brand will be launched — represents more than half of global demand; it touched $43 billion last year versus $82 billion globally.

By the time De Beers $94 million synthetic diamonds plant outside Portland, Oregon, is fully online (by the end of 2020), it will produce about 500,000 carats of diamond rough a year. The figure is a far cry from the company’s forecast of 34m-36m carats of gem-quality mined rough for 2018.

Beyond being more affordable than mined diamonds, synthetics have positioned themselves as an ethical alternative that eliminates the possibility of dealing with conflict diamonds.

Man-made gems currently make up a small part of global diamond market, but demand is increasing. Overall diamond production was about 142 million carats last year, according to analyst Paul Zimnisky. That compares with lab production of less than 4.2 million carats, according to Bonas & Co.
