The makers of a super-hard smartphone glass made partially of synthetic diamonds took part in an FBI sting on Huawei, according to a new Bloomberg report. The operation apparently took place at a Prime Burger joint in Vegas during CES last month, while a Businessweek reporter watched from a nearby gelato stand. The embattled Chinese company had ordered samples of the "Miraj Diamond Glass" from US startup Akhan Semiconductor in 2017, only to return them badly damaged. Suspecting Huawei of intellectual property theft, Akhan's founder Adam Khan reportedly contacted the FBI, which drafted him and COO Carl Shurboff to take part in its Huawei investigations.
