Art Nouveau... My handmade flameworked glass lentil-shaped bead has a base of black glass with reflective silver/black pulled through. The bead is .6875" wide and assembled with sterling silver components. The pendant is on an 18" in length (1.2 mm diameter) sterling silver omega necklace. This is a delicate necklace. The omega's end cap is removable and allows easy switching to other pendants and has a lobster clasp on the other end. The necklace comes in a lovely gift box.
