GHW and from what i noticed , there's different tone of gold too. Not sure if there's any now but when i bought mine there is. I will go for the lighter gold hardware. There's a very yellow gold hardware which isnt suitable for me though
i bought the silver hw and i regret it. at that time of purchase, it slips my mind there's lighter gold.
and i do not agree with the silver match silver hardware etc. for the lighter gold hw, it matches well too. in fact i think this will make the item stands out. how many people actually wear gold jewellery? mostly are rose gold/white gold/platinum or like some said, silver.
