Vintage Gold-Tone Screw-Back Flower Earrings with Blue and Amber Rhinestones

A pair of vintage floral-motif costume earrings, featuring a central flower design highlighted by faceted multi-color rhinestones. The construction consists of a gold-tone metallic base, appearing to be brass or plated alloy, with five outer 'petals' and a central bezel. The stones are a combination of light blue (aquamarine-colored) and amber or honey-toned faceted glass crystals. The blue stones are positioned at the compass points around the central amber stone, which is surrounded by smaller amber-colored marquise or round stones forming the inner floral structure. The backings are traditional screw-back mechanisms, a common feature identifying them as mid-century jewelry, likely from the 1940s to early 1960s. The size appears to be approximately 20-25mm in diameter. Condition-wise, the gold plating shows some minor tarnish and oxidation, consistent with age. There are no missing stones visible through the packaging, though some may exhibit slight dulling of the foil backing. No maker's mark is immediately visible through the clear plastic bag, though such pieces were common products of established costume jewelers like Coro, Trifari, or regional manufacturers. The overall craftsmanship suggests a mass-produced but high-quality mid-market accessory from the mid-20th century.
