Green Phantom Quartz 10mmGreen Phantom Quartz is a fascinating gemstone. It is a clear quartz crystal that contains visible phantoms ghost like outlines of earlier crystal growth stages that are filled with green chlorite, actinolite, or epidote. These inclusions form when the crystal stops growing for a while, mineral deposits settle on it, and then growth resumes, creating a layered phantom effect inside the quartz. It is sourced mostly from Brazil but not easy to source
