Thin diamond eternity band question

[Staceyjan]

What is the difference between an angeled common pring band versus a contoured common prong band? I am looking for a thin band to match my ER. The size of the stones in the halo and shank are .015 so I was thinking of either the following:

Or

I would also love to add a stacking band, too. But, may need to try some bands on to see how they look.

Pics of my Ear and current band whic is .07 (G-I and S12) and not brilliant cut. The band is doing nothing to make the ER stand out.

It looked like the Angeled has V prongs between and the other has rounded prongs between?

Wow! You have good eyes! Thank you. Do you think a thin one would look good that is the same size of ER?

I can't tell from your pics, but I would match the same kind of pave you have on your ering shank (or go completly different). It looks like common shared prong to me, but if you post a better picture of the shank of the ring, one of the eagle-eyed PS members can help.

Thanks, rocky salamander! I am trying to get a better pic. In the appraisal it does state common shared prong and I figured it out to be .015. Maybe these pics would show them better, the small cz bands match perfectly:
