Classic Collegiate Colors! ... These colors remind me of my college days of orange and blue (Bucknell University). My handmade flameworked glass bead is hollow. I built a transparent cobalt blue hollow bead and applied my handmade zanfirico cane (twisted canes of orange and blue). The bead is approximately .875" in diameter on an 18" in length (1.2 mm diameter) sterling silver omega necklace with sterling silver beads. The omega's end cap is removable and allows easy switching of beads and other pendants and has a lobster clasp on the other end. The necklace comes in a lovely gift box.
