Talk about a 'Wow factor'! These are Tourmaline Micro-Faceted Rondelles. They have more sparkle than the regular faceted rondelles - because there are so many more facets per bead. In addition, there are two sections in the front of (rare!) blue toned beads that really add some pizazz! The rest of the strands consist of sections that are more traditional Tourmaline colors: greens, lighter pinks, olive greens and short sections of pale and black beads at the very ends. The beads are 3.1-3.3mm in diameter on 14-14.5 inch strands.
