I will be in Delhi, India for a couple of days and would like to buy a gold chain and perhaps a bangle. I am not Indian. I would love some tips as to how to bargain when dealing with 22K pieces. I understand that gold has a daily price but how does that factor into labor and profit. I do not like the more intricate pieces but gold is really high priced so I do not expect cheap. I really want to make an informed decision. I realize each piece is unique as each store is different. But is there some sort of starting calculation in regard to gold price and labor cost? ANY help would be most appreciated. Thank you.
