I went to go look at it (because I am in love 
with Ran ^_^) but then I started to wonder...

Are you certain is from GLR? I haven't seen it in 
a few months, so I'd have to check. But his 
necklace was of a couple of long silver pieces, 
from his mother's old necklace. In the cel he's 
wearing a shell around his neck. Also, I remember 
him wearing a red vest, I don't remember his 
other outfits. Dang, my memory is fading! Anyway, 
those are my thoughts, as wrong as they might 
be :P
