Volcanic Glass by the Pound
Black obsidian isn’t a mineral in the technical sense. It’s volcanic glass, formed when lava cools so fast that no crystal lattice has time to develop. The result is one of the sharpest natural materials on Earth. Ancient peoples shaped it into blades, arrowheads, and scrapers, and for good reason: obsidian fractures to an edge finer than surgical steel. That’s not lore. That’s geology. The glassy, deep-black surface you’re looking at is the same material Mesoamerican civilizations used for ritual cutting tools and polished mirrors.
The chip format means you’re getting small, irregular tumbled pieces rather than a single polished stone. That’s the point. These are working stock. Beaders use them between rounds of seed beads. Wire wrappers use them as the focal in chip cuff bracelets. Grid builders use them to outline protection layouts. Anyone who keeps a crystal bowl on their altar or desk fills it with chips like these because they give volume and texture that a handful of tumbled stones can’t match. One pound is a real working quantity. It’s not a sample. It fills a medium-sized bowl, covers a full crystal grid border twice over, or gives you enough material to complete several jewelry projects without running out mid-work.
In contemporary crystal practice, black obsidian carries a grounding and protective reputation. It’s associated with clearing negative energy, strengthening psychic boundaries, and anchoring scattered attention. I stock it because it shows up consistently in modern crystal practice, and the demand tells me people actually use it rather than just shelf it.
Three Ways to Put These to Work
Three practical ways to use black obsidian tumbled chips in your craft and ritual practice.
- Use in a Crystal Grid Border
Lay your obsidian chips end to end around the outer edge of your crystal grid. The irregular shapes nestle together well. Set your intention before placing each stone and close the border completely for a clean boundary.
- Fill a Bowl for an Altar Centerpiece
Pour the chips into a small bowl and set it at the center of your altar. The deep black color reads as grounding and protective on any surface. Refresh the bowl placement whenever you reset your space.
- Use in Wire Wrapping or Beading Projects
Thread chips onto beading wire or hold them in place with a wire wrap frame. Their irregular edges give the finished piece natural texture. Work with 26 gauge wire for chip wrapping and 24 gauge for frames.
Tarot Fellow Standard
I stock these because the quality has been consistent order to order. The tumble finish is smooth, the color is a true deep black with the glassy surface obsidian is known for, and the chip size lands reliably in the 7-9mm range. I’ve opened enough bags to say that you’re not getting dust or powder, and you’re not getting oversized chunks that throw off a project. That said, chips are chips. They’re irregular by nature, and you’ll find some pieces closer to 7mm and others closer to 9mm. That variation is expected and it’s actually part of what makes them useful for wire wrapping and grid work, where the organic sizing gives you flexibility. Some pieces retain a slight edge from the fracture pattern even after tumbling. Handle them with care when sorting through the bag, especially bare-handed. Obsidian fractures sharp, and you want to respect that.
If you’re building out a full grid, browse the rest of my stones and crystals chips collection for complementary chip options, or explore my tumbled protection stones if you’re looking for larger grounding and protective pieces to pair with these.
Frequently Asked Questions
No, these chips are not drilled. They are not suitable for threading on a cord without wire wrapping or glue. Use them for grids, bowl fills, wire wrapping around the chip, or loose decorative use.
Chips vary within the 7-9mm range. Some will be closer to 7mm, others closer to 9mm. That variation is normal for tumbled chip stock and is what gives beading and wire-wrap projects their handmade look.
Some chips retain a slight edge even after tumbling. Handle them carefully, especially when sorting through the bag. A quick rinse and inspection before use is a good habit.
Obsidian is volcanic glass formed when lava cools rapidly. It has no crystalline structure. Ancient peoples used it for blades and arrowheads because it fractures to an extremely sharp edge.
