I don't see how this refutes the idea of the diamond industry being a scam. The only purpose for diamonds in jewelry is aesthetics, and if it's literally impossible for even an expert to tell the difference between natural and lab-grown without using special equipment, it sounds like the lab-grown ones are perfect at what they're actually being used for, so why wouldn't it be better to get the cheaper ones that are sourced ethically?
