The color of this glass is absolutely gorgeous - somewhere between blue and purple, very much like iolite or tanzanite. If you like a lot of motion and sparkle in your earrings, you’ll love these - the blue beads move around a lot, and the tiny firepolished glass beads catch the light from every angle. 

(I use sterling silver french hooks by default, but I also stock titanium and surgical steel french hooks, high-quality silver-plated leverback findings, and two kinds of clip-on earring thingies, and you can upgrade to any of those right over here.)
