Blue Agate stones are beautiful, they come in all different shades and are a lovely texture , I have hand twisted these onto sterling silver lever backs and used a ball pin to go through which sits nice at the bottom of the bead. These are also available on sterling silver hooks and studs. Please message me for clip on earrings. Bracelets and necklaces are also available in these stones, which are said to "remove negative energy " & offer protective qualities" I believe they are a lovely natural stone-Thank you
