Machines are now growing diamonds in a matter of weeks for two thirds of the price. But can they replace the magic of a mined stone? These stones were created by nature. Thousands of year ago, lab-created diamonds could never take the place of the real thing. Could they cause the 82 billion dollar diamond jewelry industry to lose its sparkle? You must travel back in time one billion years to witness its birth. Sophisticated ads have been making the case for diamonds for decades. De Beers, the world's biggest rough diamond producer by value, linked diamonds with romance in the late 1940s and dreamt up the idea of a diamond engagement ring as an essential display of love. The diamond engagement ring. How else could two months' salary last forever? Diamonds are purchased emotionally. People, in previous times, adorned gods with them. So called Queen of Diamonds, Alisa Moussaieff, sells gems to the rich and the royal the world over and has done for over half a century. For her, there's more to a diamond than its chemical structure. The energy is in the stone itself. The moment you hold it in your hand, you would feel it. It speaks to you. The real diamonds have got that energy, which can never be recreated. While sales of lab-grown diamonds are about 2% of the industry, the market is growing by over 15% a year. They've actually been around for more than 60 years, but recently, the process and the product have been refined. California-based Diamond Foundry can create a one carat diamond in two weeks. The process begins by taking a seed crystal. Right here, you can actually see a seed itself. This contains the atomic blueprint that actually makes a diamond a diamond. The reactors are then filled with a mixture of carbon, cane and gasses and those gasses are electrically separated. So, the carbon atoms themselves bond with the surface of the seed. Any gemologist in the world will put one of our stones under a grading lamp and grade it exactly the same as a mined stone. Though the difference can be detected using specialized equipment in a lab, the US Federal Trade Commission, in July 2018, expanded its definition of a diamond to include lab-grown stones. But Mrs. Moussaieff doesn't feel threatened. Lab-created diamonds may affect the lower part of the market, but it will never affect the real gems. There will be no disruption. The very expensive diamonds are still bought for investment purposes, an investment which holds its value. Now buyers can pick up a lab-grown diamond for a third less than a mined stone and as technology improves, prices will drop further. Big mined stones are valuable because they are rare. But diamond mining has been linked to conflict, human rights abuses and state corruption. Lab-grown diamonds provide an ethically sourced alternative. We're giving customers the option of a product that is 100% traceable and origin guaranteed. That just hasn't been possible in the diamond industry before. But until top designers decide to work with lab-grown stones, their potential will be limited within the luxury market. I would not call a lab-created diamond jewelry, really. I would consider it an ornament. An ornament can be made of silk, it can be made of steel and it can be made as a lab-created diamond. Lab-grown diamonds need the glamour and romance associated with mined diamonds if they're going to survive. Mined diamonds and lab-grown diamonds can coexist peacefully in the market. We hope that lab-grown diamonds growth in the industry will be a call to action for the entire industry to clean up their practices. It's a direction the diamond market is already heading. As of January 2019, Tiffany & Co, the biggest jeweler in the world by sales, will disclose the origin of all of its diamonds. It could force a new wave of transparency across the jewelry world. But, for the makers of lab-grown diamonds, the jewelry world is only the beginning. Diamonds can be used in everything from cutting and grinding to quantum computing, which can drive the true future of computing. It's not the end of the diamond industry, it's the beginning.
