These are a very rare special frame. They are Paulette Guinet, French made glasses. These are a real museum piece. They are made of high quality material and can be adjusted by an experience frame specialist if you wanted to wear them. They are in very good condition considering they were likely made in the 1950s or 1960s. They have blue, pink, yellow and clear crystal gemstones and gold inlay at the top of each peak. They will fit a womans/small size head but could be adjusted as mentioned.
