Authentic Murano Glass Fused Pendant with the hole on the diagnoal to give you a diamond shape. The hole is approximately 5mm. The size of this Murano Glass Pendant is approximately 30mm by 30mm. The pendant is fused with two layers of Murano Glass and in between the two layers colors of Murano Glass or small pieces of Millefiori and 24kt gold or .925 sterling silver is also used in some pieces. 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. You need only add a simple cord or chain to have a beautiful piece of Venetian Glass Jewelry.
