Um ok first of all when Pakistani merchants list "swaroski crystals" they mean crystals they've made themselves or whatever, real Swaroski crystals are made in germany.
i am not sure about whether they are from swaovskis or not but the cut stones have if of swarovski's , it depends which ones are used and surely they cost too much as well. the cut they have cant be done at home or in a garage.
they can range from rs 1 each (very smallsize) to rs 80-90 and over depending upon the type and size.
and the ones used on her kurti Seems to be good quality.
they arent made in pakistan and i m pretty sure they arent from china or india as well.
