So i think u all remember how did Aham buy a saari to Gopi on Korag anniversery day. So that day he learn about her taste about saari's and without hesitation he brought a saari to Gopi when navaratri.
So then now situation is the same as before as he don't know the taste of jewellery which gopi has. So he deside to go to the parek jewellers in a hide and seek mode to watch which jewellerees that Gopi admiring the most and study her like and buy it for her.
Sorry guys can't stop thinking...
