So not jewelry, but
http://www.westelm.com/ has a lot of (adorable) owl themed cooking stuff.
Measuring cups:

Butter Dish:

Also coffee mugs and cookie jars that I'm too lazy to link to. If I were a Chi O or Kappa I would grab these so fast (probably will anyway, just without the sorority connection).
ETA: Also salt & pepper shakers! Note that the butter dish is on sale for $6!
