Oroton Blue Emerald-Cut Costume Earrings

This is a pair of vintage-style costume earrings from the Australian luxury brand Oroton. Each earring features a central emerald-cut synthetic stone in a deep navy or sapphire blue hue. The central stone is held in a yellow-gold-toned bezel setting, which is further surrounded by two concentric halos of clear crystals, possibly glass or cubic zirconia, set in a silver-toned or rhodium-plated base. The design is octagonal in shape, mimicking a classic Art Deco aesthetic. The earrings appear to be in good pre-owned condition with no missing stones visible in the image. They are presented on an original tan-colored flocked velvet or suede-texture display card that features the 'OROTON®' brand logo in dark brown serif lettering. The card is seated inside a two-tone jewelry presentation box. Based on the branding and design, these likely date from the late 20th century to early 2000s. The craftsmanship reflects the higher-end costume jewelry market synonymous with the brand's reputation for classic elegance.
