This piece completed my set perfectly.  The aquamarine matches a necklace and earring set I've got from a defunct jeweler that are white gold.  The band isn't thin (which you run into at this price point!), the prongs are solid and the recessed diamonds still sparkle without detracting from the aquamarine.  The blue topaz is the same shade of blue as the center stone.  What you can't see from the pic is the very large undergallery - had to look that up ;)!  It sticks out further than I would have expected, but I've worn it for a week and it hasn't caught on anything.  Love!
