Obsidian Round 10mm

These 10mm obsidian rounds are made from natural volcanic glass — genuinely formed by rapidly cooling lava — giving you a stone bead with serious geological credibility. Deep, glassy black and weighty in the hand, they're a go-to for anyone working with root chakra, birthstone, or dark-aesthetic designs.

Obsidian's natural glass composition produces a surface that's smooth and reflective with that characteristic deep black depth — no two beads are identical, and you may see subtle natural variation in sheen.

What to make with them

At 10mm, these rounds have the presence to anchor a focal strand in a knotted gemstone necklace or carry a single-material bracelet on their own. They also pair well with metallic spacers or chain in earring drops where that volcanic-glass weight adds satisfying movement.
