Thanks for the report. You are right: the Maple Necklace Gem cannot be found anywhere right now, so the Mind of Maple Necklace cannot be awakened into its Sealed, Restoring or Awakening forms. In the original game the gem was only handed out during a short event, and there is no faithful record of how Mr. Moneybags performed the awakening, so we have not made one up. It is waiting on a decision from Mark about how it should come back. Until then the Mind of Maple Necklace from Mr. Moneybags' quest is the only one you can wear. This report will be updated when that is decided.
