This necklace and shibori set was sold as Jalina's wardrobe. But if you look closely, Jalina's necklace doesn't look like this at all. After some research, I discovered that it was in fact Andina's necklace from the Season 3 episodes "Of A Demon in My View" and "The Awakening" (3.11 & 3.12). The screen captures prove it. As for the shibori, I don't know of it's hers or one that was worn by the other servants as seen in the last screen cap. Thanks to cap-that.com for the screen captures!
