Yves Klein Blue Necklace by I. Ronni Kappos

German vintage glass beads, nylon cord, 14k gold fill findings, total length: 18 inches, pendant drop: 2.25 inch drop

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 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 1920s and 1930s, they are rare and highly collectable. This makes all of her designs limited editions.
