Facets Eternity vs. Memoire Petite Prong - Height Difference?

[alloamie]

I''m trying to decide between the two rings - is there a big difference in height & width of the bands?
Particularly .5-.75 total ct weights.

I''m waiting on a price quote from Pearlman''s on the memoire band (platinum size 4.25) - does anyone know what the price difference might be between the memoire & facets?

Thanks!
