It doesn’t look like an X, it looks like an upside down cross.
Until someone finds a high-resolution photo of that necklace, it could be a (+) sign, an X sign, or any number of things. Podesta’s creepy emails talking about “pool parties” with “11, 9 and 7” year old children to “entertain” them is one thing. Dinner parties with a known occultist performing rituals...that is truly disturbing. Critiquing blurry photos of jewelry is just dumb.
