i head this so much when i was visiting pakistan last year...its common for thieves to target brides and guests at weddings since naturally, people wears tons of jewelry. at my cousins wedding, she did wear real gold jewelry. but all my khalas and cousins were scared (since we were all visiting from out of town to attend her wedding) and all wore artificial jewelry that was gold plated and it looked fine!
so don't worry :). karachi and lahore have some awesome artificial sets that look so real! i actually purchased one and took it to my local jeweler here in USA and even fooled him! he kept asking me, this is real nah? when did you buy this from us? lol, i was like you're the jeweler and expert- you tell me!
funny --he is not a khandani jeweller probably
