Bold and beautiful! A classic Art Deco design. What a wonderful combination. Only the clasp is marked "Czechoslo" but both clasp and earrings are the same size clear glass and go so well together. The earrings are a bit more faceted and have a screw back in copper (?) while the clasp has a silver tone base metal. It is a fantastic look! The clasp measures 1 3/4" across and the earrings measure 3/4". In fantastic vintage condition!
