Handmade by I. Ronni Kappos, this jewelry is composed of vintage German glass and gold-filled findings. The glass comes from the famed, but long-defunct German glass works 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 1920s and 1930s, they are rare and highly collectible. This makes all of her designs limited editions.
