Authentic Murano Glass bead in the Pastello Aventurina Style, where we begin with a base of opaque Murano Glass and then sprinkle splashes of Avventurina around. The bead is then completely encased in clear Murano Glass giving it depth and the Aventurina gives it sparkle. It's a economical line but can be dressed up. This bead is a 14mm round with a center hole nominally 1mm in diameter. As they are handmade and a 14mm is really tough to gauge, they may run a little larger. The color in this one is a base of Lapis Blue Murano Glass.
