Utility patent # 2,583,988 (for earring clasp) issued to Frederick A. Ballou, Jr. & Rogers T. Stafford in 1952 (application filed in 1949)
Large golden and brown topaz glass stones are prong set in gold-tone metal with round citrine glass accents in these clip-back earrings by Elsa Schiaparelli. The exotic three-sided shape of the large stones enhances the three-leaf clover design, and the elaborate construction of the earring backs exemplifies the maker’s quality. This color combination can be seen in other Schiaparelli pieces. You can see the utility patent for the earring clasp here, shown below the names Frederick A. Ballou, Jr. & Rogers T. Stafford.
