Snowflake Obsidian tumbled stones are polished, jet-black volcanic glass pieces with white or gray "snowflake" patterns, known for bringing balance, purity, and grounding by revealing and releasing negative thought patterns, promoting calm, and aiding in self-reflection, often used for meditation, stress relief, and chakra balancing (Root Chakra). They're popular for collections, gifts, or personal healing due to their beauty and metaphysical properties.
