A gentle soft milky white bead, with a mellow blue centre.  The bead measures approximately 11mm x 12mm and has a flat top & base with fluted indentations to both sides of the bead.  An unusal little treasure.   

 

Not every bead is alike.  They are vintage in age...even though these beads are in beautiful condition, the odd bead might have a very minor flaw

A true collectors item!
