First, my e-ring:
 
In case you're curious, the side stones are peridot (August - my birthstone), blue topaz (December - his birthstone), and black diamond. (He customized it all by himself!)

Okay, here's what I'm trying to decide between:
1) A half-eternity band, channel set (since my side stones are channels), fairly small/thin.
2) The matching band that "goes with" the e-ring, only with all diamonds instead of the custom stones.

I went to the jeweler and these are the closest I could get (though they're rather big on me and look a little goofy).

1)

My hand kind of looks dead there...excuse that. Anyways, the band I'd actually get would be the one below, but it's curved and this one is about the right width so I added it to get a feel of how the straight one lays next to the e-ring and how the thin-ness looks on my hand.

I guess they're pretty similar...This curved one just looks shinier to me. :P

2)

This isn't actually the ring that goes with it, but it's about the same width. The one that this is supposed to represent would have 7 stones like my engagement ring (same size and lined up exactly -- only they'd all be diamonds instead of matching the e-ring's stones).

The most important thing to me is accenting the e-ring and not taking away from it. It's custom and so "me", I don't want to take away from that at all and keep the focus (at least most of it -- some attention to the sparkly band is good ;) ) on it instead of the band if possible. I want it to accent the e-ring instead of looking like two separate rings...if that makes sense.

What do you think? Do you think the "matching" one is too thick (I have pretty small hands and I'm a little worried it will look like a lot of ring)?

I probably should have phrased that better... The first ring would be a straight version of the second picture under "1". ...If you followed that. :P For the first ring first picture, it's supposed to demonstrate the width and how the eternity-ness looks with my e-ring. The second one would be the curved version of the straight band I would get, if that makes sense. I'd be getting the straight version of that ring.

@mammamia: Thank you! :D Yeah, I think I'm kind of leaning towards that... I thought about doing a plain band, but I saw a picture of someone else's ring where their e-ring was at least partial eternity and the band was plain and I felt like it kind of looked awkward and even drew decent attention to the plain band just because it looked almost out of place next to the diamond-y one. Also, these are shinier. ;)

@erostron: Thank you very much! They also happen to be my fiance's and my favourite colours. :D

Thank you so much for the input, guys! I really appreciate it!
