In 2018, the Federal Trade Commission in the United States ruled that lab-grown diamonds and mined diamonds were chemically, optically and in physical make-up, the same. Rings with the Michael Hill man-made diamonds, created by diamond lab Fenix, cost between $7999 and $17,999. The company's lab created 2 carat diamond ring with a 14ct white gold band was being advertised online for $17,499 while a similar ring with a 2 carat mined diamond and 18 ct white gold band was being sold for $34,999. The only difference between a created and a mined diamond is the origin of the stone," Bracken said. The argument that these diamonds were more ethical than mined diamonds was problematic as well, he said.
