Delicate Rings

I'm usually a big fan of thick chunky bands that make a statement on my fingers, but for some reason lately I've developed a fixation on thin, delicate rings.  Whether they are stackable or single, I just keep wanting them...

This one is the only one not found on etsy.  I love the simple hexagon.  I suppose loving geometrical shapes is slightly nerdy of me, but oh well.

These are two stacking versions I like.  They are both simple, the first being slightly more so.  Not sure if I'd go with a single "r" on the initial rings, or with a triple initial monogram feel.

This option with simple gold beads is also stackable, though it is sold alone.  In fact, the product page shows it stacked with it's silver twin and they look quite lovely together.

This ring is the most statement making (and expensive) of the bunch, but I can't tear my eyes away from it.  The combination of the thin rose gold band with the lightly blue color of the aquamarine is simply gorgeous...
