Composed of vintage German glass, silk cord. The glass comes from the famed, but long-defunct German glassworks in the Sudetenland region of Bohemia. The molds and chemical pigments used in prewar glass production from this region are no longer available, which is why so many of the shapes and hues are very unusual. Since these beads were made in the 1920’s and 1930’s, they are rare and highly collectable. All of I. Ronni Kappos designs are limited editions. Beklina exclusive.
