Some books mentioned that crystal accessories can be cleansed and charged in an amethyst geode. Can I use the amethyst geode in CLT Geomancy Grid to do the same?
No, unless the amethyst geode is not part of CLT Geomancy Grid. The crystals of the Crystal Grid are specifically assigned to energise, harmonise and balance the house energy. Just like you would not use your personal toothbrush for other housecleaning chores; do not use the crystals in the Crystal Geomancy Grid for other functions, to avoid energy contamination which may be detrimental to the house occupants.
