In the Caste System page under Rubies, "Garnet describes them as 'common', seeing as they are all originally identical to one another." Believing what Garnet said is true, there's just multiple rubies out there that can be exactly near each other even the same gem placements. I doubt they're the exact same Ruby from "The Answer". Even if they are same, their roles are too minor and probably not sufficient info to quality for a page in my opinion. Just giving my two cents in the case.
