A striking round bead with a glossy iridescent finish that shifts through vivid rainbow tones of violet, teal, gold, magenta, and blue. The dark metallic base enhances the oil-slick effect, creating a luminous, reflective surface that catches light beautifully from every angle. Perfect for bold jewelry designs, statement bracelets, necklaces, and modern craft projects. Smoothly drilled for easy stringing and a polished professional finish.
