Kissing the Black Stone during tawaaf is one of the established Sunnahs of tawaaf, if it is possible to do it without pushing and shoving or annoying anyone else by your action, following the example of the Messenger of Allah (blessings and peace of Allah be upon him). If it is not possible to do it except by pushing and shoving and annoying others, then one should not do it, and it is sufficient to point to it with one's hand, especially for women, because the woman is ‘awrah and because pushing and shoving is not allowed for men, so it is even less so for women. If it is possible for a woman for kiss the Black Stone without pushing and shoving, it is not permissible to her to uncover her face whilst doing so, because of the presence of men who are not mahrams for her in that place.
And Allah is the source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
