Rainbow Obsidian Bracelet — 8mm Mirror-Black with Subtle Sheen

Quick Highlights

• Bead size: 8mm round
• Finish: High-gloss polish
• Style: Elastic stretch
• Key features: Volcanic glass with an iridescent “rainbow” sheen visible under direct light

Introduction

Deep, mirror-black at first glance; tilt under a spotlight and soft halos of green, purple or bronze appear. Clean 8mm rounds offer sleek everyday wear with collector appeal.

Geological Details

• Type: Obsidian (natural volcanic glass; mineraloid)
• Structure: Amorphous
• Chemistry: Silica-rich glass with trace iron/magnetite inclusions
• Optics: Thin layers/nanoinclusions create interference colours—the rainbow effect
• Hardness: ~5–5.5 Mohs; conchoidal fracture

Aesthetic Appeal

Inky, high-polish surface with crisp reflections. In diffuse light it reads black; under a point light individual beads show iris-like rings or halos of colour.

Metaphysical Properties

• Protection & Grounding
• Emotional Release
• Rainbow aspect: Clarifying yet gently uplifting

Rarity

Rainbow obsidian with visible sheen in well-matched 8mm beads is less common than standard black obsidian.

All-black minimalism with a hidden spectrum—easy to style, meaningful to wear.

Specifications
