This large Black Obsidian arrowhead has a deep glossy black surface and pronounced sharp edges. Its substantial size works well as a display piece while still showing the glass-like fracture patterns Obsidian is known for.LocalitiesMexico, United States, IndonesiaObsidian is a natural volcanic glass formed when silica-rich lava cools rapidly before crystals have time to develop. Its characteristic curved, shell-like fractures create the sharp edges traditionally associated with knapped Obsidian tools and points.Measurements - 11cm x 4cmCare - Obsidian can form very sharp edges. Handle carefully by thicker or blunt surfaces, display securely, and keep away from children.Why this piece is interestingObsidian can fracture into exceptionally sharp edges because it has no regular crystal structure. This property made volcanic glass an important material for cutting tools and projectile points in many ancient cultures.MetaphysicalProtection • Grounding • Clarity
