That doesn't really help for proportions because it's too close up. These are more real life perspective-ish...
These threads really helped me when I was trying to work out what sizes look like. Great when it's not that easy to get to the shops....
This thread is interesting to see different size rocks on my size finger.
My e-ring is between a 5 & 5.25. It's 1.65 ct (7.5mm). I'm not sure how wide the band is.
The eternity band is the same size and about 2mm wide.
The plain band is a size 5 and 2mm wide.
