Karma, Pearls, or a Horseshoe?

The search begins for gifts for my BM's. I would like to give them each a piece of jewelry to wear on the big day as well as something personal for each of them.
One of my daily reads (i have subscribed to waaay too many blogs in my Google reader) pointed me towards Dogeared. Check. it. out.

(the karma necklace, in hopes of surrounding us with good karma on our big day!)

And possibly my fave, just because of the wording on the card:
"pearls represent the best within us. let your necklace be a daily reminder of the beauty and simplicity of our friendship! enjoy and believe!"

(Pearls of Friendship)

Others I liked were the sister heart for my sorority sisters and the lucky horseshoe...because everyone can use a little luck on their big day! The simplicity of the design is what I loved the most. My BMs will not be decked out in chunky/prom-y jewelry while standing next to me!
