For the uk guppies, and those who have knowledge about shopping in the uk

i can’t say if all jewellers in pakistan do this, but there are definitely dishonest ones, as opposed to, for example, in dubai.
my mom bought a pair of earrings in pakistan that she was told were 22K gold and she paid the price for 22K gold too. a few years later, she tried to exchange them in dubai for something else, and they checked them, and it turned out they were only 18K! so i’d be careful.
