What's the difference between engagement rings / eternity rings / solitaire rings..? Girl's rings, not blokes. I mean I know one is for engagement etc etc I mean to look at. Cos they all look very similar to me, with stones in. If I saw a "engagement ring" would it be wrong for it to be bought as an eternity ring? Do you know what I'm getting at.. is there something specific about them in any way or is any ring with a stone in it good for any occasion? If you can use any ring for any occasion, why on jewellery websites are they split into engagement/eternity/solitaire instead of "rings with stones in"... help?
