Our Bollicine line which features a small body of 24kt gold foil and light topaz which has been carefully prepared so that little bubbles randomly appear and then completely encased with the same color Murano glass. Each of the bubbles is planned - it's no mistake and the effect is fantastic. It's a technique we borrow from the furnaces of Murano and often used in our Murano Glass Vases. This entirely handmade Murano Glass Bead has a 1mm hole.
