POLISHED RAINBOW OBSIDIAN

Rainbow obsidian is nature’s most dazzling volcanic glass, polished to reveal electric bands of iridescent color that shift with every angle of light. Formed in silica-rich lava flows that quenched in an instant, its thin internal bubble layers create a natural optical rainbow effect unlike any other stone. Each polished piece becomes a mirror of volcanic fire and physics, crafted by Earth and finished by hand for collectors who chase rare color and flawless luster.
