A lot of yellow gold hate on here. I don't like white gold / platinum etc because it's just so ubiquitous, it's become a bit boring. I didn't want my engagement ring to look like everyone else's (platinum square cut diamond, yawn).
Mine is rose gold. Bit annoying that rose gold got massively popular not long after I got it but I'll still have it when rose gold is out again, haha! Plus it looks gorgeous with the stone (a peachy coloured sapphire).
I agree that it depends on your colouring. I'm very pale and silvery colours just get lost on me.
DH has a very simple rose gold band - chunky and with a square edge. It's gorgeous. I love seeing him in it.
