What's the Diff? Cocktail Ring Edition

This is the Sunset Ring at Banana Republic for $39.99 (from $49.50).

This is the Claw Set Faceted Ring at ASOS for $10.15.

Frankly, aside from the setting, these look the same to me.  When it comes to costume jewelry, I recommend going with the least expensive options that look the most expensive.  Considering these are both base metal and glass or resin, I'd go with the $10 option unless the shipping cost is way more than Banana's.
