if you breath on it does the fog stay or disapear quickly? if you run water on it will the water bead up or run off? if you hold it over some newspaper or any type of small print are you able to read through it? does it reflect shades of rainbow or shades of white and gray? watching
sorry but it sounds fake, diamonds reflect gray and white, and they are porus so the fog should have stayed , and thats also why the water would have beaded up and not run off, still pretty though great for crafts
