This is an authentic Venetian mouth blown bead made in the furnaces of Murano by using glass canes fused together, which gives definitive color stripes.
The bead size is approximately 25mm and the holes are irregular as they are blown and cut with the glass shears while still about 900 degrees so it is impossible to have regular hole sizes.
Hole size is approximately 3.5MM.
You will receive one bead.
