This outstanding piece of Mod design was done by Kunio Matsumoto. He was an architect who designed a line of jewelry for Trifari in the 1970’s. The silvertone metal has a brushed finish except for the band that encircles the lucite centerpiece. That is shiny. This is a clamper style bracelet. It measures 6 3/8 inches when clasped and is 1 1/8 inches wide at the widest part. It is marked Trifari and Kunio Matsumoto. In my opinion this is one of his most dramatic designs. Bracelet is in excellent condition with no signs of wear.
