Rainbow Beaded Statement gold-plated brass (sterling silver posts) Hoop Earrings

This is a lovely pair of rainbow beaded gold-plated (with sterling silver posts) dangle hoop earrings. The multicolored beads are made of enamel. They are 30mm by 45mm (or roughly about 2 inches down and 1.3 inches across). Note: the earrings are somewhat heavy to wear. My relative believes she purchased these earrings from Sundance a long time ago but upon searching, the earrings appear to have been sold by Madewell more recently (possibly the artisan who made them sold them to different brands/companies over the years).
