I got most of my jewelry from Tanishq in Karachi. I had a pretty good experience with them, cant say the same for some other clients of theirs that came in while I was there and argued with them about selling their jewelry to other people.
The one place I would definitely recommend going to is Naurattan. It's right across the street from Forum. They've got amazing jewelry and great customer service.
thanks sumorani....where is tanishq located in karachi..do they have any website
