I just freaked myself out when I saw the miniature cobweb like features all over my diamond. I noticed it in a jewelry store today when I was trying rings with diamonds of lesser quality. My setting (Tiffany style) is very scratched and have similar cobweb like features inside the progns and on the outside of the ring. Is it possible that the setting grain (finish) would shine through the diamond when in a strong indoor light? I got GIA cert, diamond is VS1 and F and Excellent for both polish and symmetry. The diamond is otherwise beautiful when in daylight and sparkles beautifully. I''m just concerned that this is something internal (maybe clouds or feathers). By the way, I asked jeweller to steam clean my diamond (I thougt it''s maybe fingertips or something). I hope it''s a setting (that can be replaced no problem). Please help!!!
