Sorry for the double post.
I decided to make a Ravenclaw necklace. I used silver lame cord to crochet the links between the beads, the center of the trio of beads is a 10mm medium blue faceted bead (there are 19 of them in total), the two side beads in the trio are 6mm amber bicone beads (38 total). The length of the necklace is 66 inches (yeah, it is really long and looks best tripled up in my opinion.)
Here are some photos:
I particularly like the blue beads because they're part clear and part blue, so it gives them a very airy quality which I think of as synonymous with the nature of the Eagle and therefore, symbolic of Ravenclaw.
