for my brothers wedding we got churiyan from Aus and took with us to pakistan. they had company stamp with karet stamp and design was far better than pak. But we gt set from pakistan as to match with clothes. if u get gold with out stamp its hard to sell later.
but even in pakistan churiyan are expensive. on average 1 bangle has to be minimum of 10grm other wise they will break and cost of 1 gram is about $50aus and that is about 500 for 1 bangle and than if u want 12 you can calculate.
i got 2 bangles recently 22 gram each. i had budgeted to buy 4 minimum but i couldnt find so ended up getting 2 only but they are heavy and strong.
you will not get ready made sets but what i did last year is got 2 big/heavy bangles and 6 small (slim style) 10 grm each. both had similar pattern and colour so i start using as a set.
