Well just that really.
I have lots of pretty silver jewellery, rings, etc (not expensive) which I never wear as I am always wearing my wedding and engagement rings which are gold. I also have a gold eternity ring which I wear on my ring finger on my right hand, so I can't wear all silver on my right hand.
I think the mixture of gold and silver together looks odd, but maybe that's because I'm not used to it.
Sorry, a bit of a 1st world problem I know, but I'm feeling sad that these things never see the light of day.
