We love the subtle blue/violet hue of Iolite. However, finding nice iolite in a larger sized bead is not an easy task. But for you, we did it. (Okay, maybe for ourselves also.) The faceted iolite and flashy moonstone rondels are accented with 24K vermeil beads. This necklace is 16.5 " with a lobster clasp and 2" extender finished with an iolite bead. Not for the timid because you will be noticed.
