Crushed Black Obsidian offers a deep black appearance with the distinctive glassy character of natural volcanic glass — a striking material for sleek, dark inlays and dramatic high-contrast designs.
Each 10g bag contains carefully sorted Black Obsidian available in four grades: • Rough (4–8mm): Larger pieces suitable for custom crushing or bold, chunky textures. • Chip (2–4mm): Great for clean fills where natural texture still shines. • Flake (1–2mm): Ideal for finer channel inlays or blending with other stones. • Powder (<1mm): Perfect for detailed work, tight gaps, or as a colorful additive in resin and adhesives.
All material is raw, untreated, and packaged in-house by Bentwood Ring Supplies. Natural variation in color, shape, and opacity is expected — that's what makes each piece unique.
