Crushed Black Obsidian Medium Powder - Natural Gemstone

Our medium-grind black obsidian powder hits the sweet spot between visible texture and workability - fine enough to blend smoothly into resin, coarse enough to show the stone's distinctive dark grey/black color. Formed from volcanic glass, black obsidian has a consistency and color unlike crystalline stone powders.

For Jewelry Makers & Crafters

Medium black obsidian disperses evenly in resin without clumping, making it ideal for resin jewelry, pendants, and nail art. Creates a deep, dark tint with subtle texture. Also works for candle making (surface embedding), fine mosaic work, and detailed inlay.

For Wood Inlay & Detailed Art

Works well for finer inlay details and narrower grooves where coarse particles won't pack cleanly. Good for pen blanks, calligraphy inlay, and smaller decorative accents where a deep black effect is the goal.

For Orgonite & Energy Art

Medium black obsidian blends cleanly with resin and metal shavings in orgonite pyramid layers while maintaining visible dark stone content. Also used in crystal resin sculptures and layered castings.
