Need some help deciding between these styles for an eternity ring for the wifey. She currently has a 1 ct Cartier 1895 plain round solitare style, about 2 mm in width on a 3.5 finger size. She would like an eternity band that she can wear by itself. Her current wedding band is a plain platinum 2 mm band, but she feels this is too thin by itself, so I am think something in the 2.3-2.5 mm range.
I like the Tiffany Novo because you can''t really see the gaps between the diamonds.
I like the Tiffany Legacy because with the milgrain and the bead setting, you also can''t really see the gaps.
The Cartier Ballerine is classic, but the beads/gaps are a little more noticeable.
Which do you all prefer and which would go better with her e-ring?
Here''s her e-ring:
