Yahoo News reported that China is taking on the world's diamond miners, using sophisticated technology to offer increasingly cheap and real-looking knockoffs that threaten to upend the lucrative fine jewelry market.

The technological disruption seen in medicine, autos, banking and countless other sectors is spilling over into diamonds, where an oligopoly of just four miners controls more than 60 per cent of production, according to consultancy Bain & Company.

It is happening as China taps the know-how it developed in becoming the world's biggest maker of synthetic diamonds used primarily in the industrial cutting tools market.

By doing so, China now makes 56 per cent of the world's gem-quality synthetic diamonds, far outpacing second-placed India.

While synthetic diamonds right now only account for 3.5 per cent of the world's diamond jewelry, the share could grow to six per cent in four years, and even more later, says Yahoo News interviewed Paul Zimnisky, a New York-based independent diamond sector analyst who said that during the past "few years Chinese producers had been upgrading existing equipment to produce larger, better-quality synthetic diamonds for use as jewelry. China already has the infrastructure in place which allows for high production scalability of higher-quality synthetic diamonds, as existing high-pressure high-temperature equipment is upgraded," Zimnisky said.

Five years ago, a "fake" diamond cost about 10 percent less than the real thing. Now the discount is about 50 percent. And within five years, Zimnisky estimated, it could be 90 percent.

"Technology has progressed rapidly, not only are the lab-grown diamond producers able to produce bigger stones … but also better clarity and color," Georgette Boele, senior precious metals and diamonds analyst at Holland-based bank ABN AMRO, wrote in...
