real gold is expensive but it's a good investment! Just think from all the money you spend on a wedding what you can re-use (in money terms) again?
I've picked designs from the internet and am having them made in real gold for my wedding. But nowadays the majority just go for artificial.
Most people say they can match the artificial jewellry better with their outfits than real gold, which is true and also if you go to the gold jewllers they don't really have nice designs as they used to, which is why i've had to order mine.
