Black Rainbow iridescent glass tube beads 
approx. .5 ounces
 
Glass tubes, about 1/4th inch long (with slight variations). These tube beads may have black at their core, but their outside exhibits a slinky oil-slick rainbow of indigo, fushia, turquoise, and jade. A must-have embellishment!
 
Perfect to use with epoxy clay for mixed media mosaic assemblages!
