Re: Need advise on Gold jewellery buying ..
^ But if they go out of fashion, you can always melt them down and have something else made? 
Yes you will get a LOT of gold on your wedding… (even if you state that you don’t, desis will be desis)… so don’t go crazy with buying lots, but like Hitch said, it’s an investment.
Just buy what you like (and know you will wear), and the amount you think is morally acceptable… i know of this girl my nieces age, who recently got married, and her FIL (i suspect he’s into something dodgy) actually gave her £50,000 just to spend on Gold 
Who wears that much Gold these days??? That’s enough for a house deposit…heck i’d buy shoes and other things,instead of Gold with all that cash! 
Just be wise, you will know what is right
