Please make note apart , if you are bringing wholeseller items like gold , silver or diamonds jewellery ( because many persons go for shopping gold to Dubai and comes back to Pakistan ) the limit is also including the invoice prize of these jewellery .
Thats why many persons tries towear as much jewellery as they can , so thye can say is for personal use , and avoid the goverment tax pay.
