I'm confused about Marle's pendant. I mean, in the PS1 version of Chrono Trigger, you can see Marle's pendant in one of the FMV pictures, and you can see that its color is blue, but since Marle's pendant looks exatcly like Schala's pedant, and they say that Schala's pendant was made from the same red rock as the Mammon Machine. Why, then, was the pendant blue and not red?
