SZV collections are made of mouthblown Murano glass. Shape and size of each glass bead originates from few gestures, the lowest use of tools, and no mould. The images of the creations found in the website are usually similar to the original pieces. A slight fault or variation in measure or colour of the glass parts are the distinguishing marks of handwork. The single blown glass elements of necklaces, pendants and earrings are thin enough to make even big accessories lighter; whereas a 4-5 mm thickness of bracelets and rings makes them shock-resistant.
