>When I showed her what I'd picked out, it quickly devolved into a lot of uncharacteristic tears and shouting. It took a few more tries, and then she explained. Apparently a lab grown diamond meant my love for her was also artificial, a budgeted ersatz stand-in for the real thing

I'm wondering how, if you picked it out, she even knew the diamond was lab grown? Did she start grilling you immediately? Or did she get the microscope out? Maybe I'm a total moron but I can't tell the difference by just looking at it.
