The half-Pendant in "Chandragupta" was definitely in the King's Storeroom, and I'm on the "It was IN the pot" team on that one.

Otherwise, while I have no real proof, I'm willing to guess the half-Pendant in "Elizabeth I's Golden Ship" was on an actuator in the Cave of Sighs. That would explain why we wouldn't see it, but the contestants still could have encountered it when they needed it. Alternatively, it might have been on the Heart-Room-to-Room-of-Golden-Idols actuator for the same reasons.
May I request a good-quality screencap for "The Bifocal Monocle of One-Eyed Jack," by the way? I've never been able to make out the alleged half-Pendant in the Tomb of the Headless Kings.
