After observing my diamond and lots of others closely that are not officially labeled hearts and arrows - I realize that most round brilliant diamonds have hearts and arrows in the standard cut. The perfect hearts and arrows can be given the credit but the not so perfect hearts and arrows that are in most well cut diamonds look pretty good to me. As I see it, there are plenty of well cut diamonds that are hearts and arrows some are just off very very slightly. So I wouldn't pay for the perfect labeled hearts and arrows - it's a waste of money.
