Black Obsidian Dagger

Black obsidian is a natural volcanic glass (amorphous silicon dioxide with trace minerals) traditionally associated with grounding and protection. This dagger, about 7 inches long, is hand-carved and knapped from glossy black obsidian to a sleek, dramatic edge — a striking altar or display piece. Quick facts Stone Black obsidian Composition Volcanic glass (amorphous SiO2 with trace minerals) Hardness (Mohs) About 5 to 5.5 Color Glossy jet-black Chakra Root Traditionally used for Grounding, protection, cutting through negativity Care/Water-safe Safe to wipe with a damp cloth; it's glass, so the knapped edge can be sharp and the piece can chip if dropped Meaning & history Obsidian forms when lava cools so fast that no crystal lattice has time to develop, leaving a natural volcanic glass rather than a true mineral. Knapping — chipping the glass to a sharp edge — is an ancient technique, and here it's used to shape a decorative dagger rather than a tool. In crystal tradition, black obsidian is a strong stone of protection and grounding, tied to the root chakra, and often associated with cutting through negativity and revealing clarity. Many people keep a piece like this on an altar as a symbolic tool.

How to use it This dagger is meant for display, not for cutting — keep it on a stand, altar, or shelf as a symbolic piece rather than a functional blade. Many people place it near an entryway or workspace as a visual reminder of protection and grounding, alongside other pieces from our balance & wellness collection. Care & cleansing Black obsidian is natural volcanic glass, so a soft, damp cloth is fine for wiping away dust; avoid harsh chemicals and abrasive scrubbing. Because it's glass, this piece is brittle and the knapped edge can be genuinely sharp, so handle it carefully, keep it out of reach of children, and display it somewhere it won't be knocked or dropped. To cleanse the stone's energy, many people simply wipe it down and rest it in a quiet spot away from clutter. Frequently asked questions Is the blade actually sharp? Yes, the knapped edge can be genuinely sharp. This is a decorative, symbolic display piece, not a health product, tool, or weapon, and it should be kept out of reach of children. What is black obsidian made of? Black obsidian is a natural volcanic glass formed from rapidly cooled lava, not a crystal with a defined mineral structure. Is it fragile? Yes, since it's glass, it can chip or fracture if dropped or bumped against something hard, so handle and display it with care. Can I clean it with water? Yes, a soft damp cloth works well for wiping the surface. Avoid harsh chemicals and dry it promptly. What is black obsidian traditionally used for?
