It crystallizes in the trigonal system and typically develops as small rhombohedral crystals or crystalline crusts within oxidized zones of copper deposits.\u003c\/p\u003e\u003ch4\u003eTraditional \u0026amp; Metaphysical Associations\u003c\/h4\u003e\u003cp\u003eIn modern crystal traditions, dioptase is associated with compassion, emotional renewal, forgiveness, and heart-centered intention-setting.
