Natural Rainbow Eye Obsidian Rectangle Plate Bead Bracelet 14mm 17mm 19mm | Artisan Supply

Natural Rainbow Eye Obsidian (Rainbow Obsidian) is a unique volcanic glass formed during the cooling phase of silica-rich lava. Microscopic inclusions of magnetite or microscopic gas bubbles aligned in parallel layers create a subtle, luminous iridescent sheen—often displaying shifting shades of green, violet, gold, or grey under direct illumination.

Precision-shaped into smooth, curved rectangular plate beads, this cuff-style bracelet highlights the silky chatoyant glow across each bead surface. Available in three distinct bead length options—14mm, 17mm, and 19mm—and strung to fit standard 17–18cm wrist sizes, this versatile geometric bracelet brings a refined, modern look to natural volcanic stone jewelry.
