This Authentic Murano Glass Fused Pendant features Sterling Silver Foil with assorted pieces of Millefiori, Mosaic overlaid and clear Murano Glass encasing these decorations..

These pendants are fused with 2 plates of Moretti glass and in the middle of the sandwich is .925 sterling silver and our millefiori. These pendants are slumped after the fusing to give them slighty curved shape which helps hold the pendant close to the body and sits on the cord nicely.
