A "donut" hole in the center of the "night sky" in this focal bead exists for creative beaders and stringers to do something with! One could fashion a sun or a moon or a face or a star and string it or have it coming out of the stone! I hand cut this focal bead. Measurements in the title. A barrel shape with a satiny, matte finish. The rough material I used for this is a kind of rhyolite called wonderstone and it is from near Salina, Utah, hence the name. With the black centers it is very different looking from most wonderstones and in some ways appears like a picture jasper with a night sky, but it's not a jasper, it's a rhyolite. CHAIN NOT INCLUDED.
