This bead is made from borosilicate glass. It is made using the "inside-out" technique. I use a clear tube, open it up, put the designs on the inside of the tube using colored glass, dichroic glass, and fine silver gold fuming, and then close the tube down and shape the bead. It measures 1.25" long by .75" wide.
Because of the nature of fumed work, it will look different in front of a light background than it will in front of a dark background.
