Green Fluorite, green calcite, chrome diopside... I would have imagined
)) more yellow/orange stones, too, but when I checked in on my intuition re fluorite, green fluorite got the nod, and as I searched further, many stones with a quite rich green, both opaque and transparent, came up... Beyond crystals with a defined use in assisting creativity, I like any stone which has interesting fissures, fractures, etc as these readily offer doorways/windows to move through...especially for story-telling, because, if you let them, those fissures and markings will just gift you with their stories
