Vintage Sterling Silver and Oval-Cut Ruby Stud Earrings

This pair of vintage stud earrings features two oval-cut gemstones, identified by the user as rubies, exhibiting a deep, saturated magenta-to-pigeon-blood red hue. The stones are approximately 6mm by 4mm and are securely held within detailed silver settings. The construction features a distinctive twisted rope or milgrain-style border encircling the central stone, which is a design hallmark of mid-to-late 20th-century artisan jewelry. The metal appears to be sterling silver, as indicated by the natural dark gray oxidation and patina visible in the recessed areas of the rope detailing. One earring is shown with its original butterfly friction back, while the other shows the bare post, suggesting a standard pierced-ear fitting. The gemstones show significant clarity with facets that catch the light effectively, though there is visible surface dust and minor oil residue from handling. The overall condition is good with no visible chips to the stones or deformation of the posts, although they would benefit from professional cleaning to highlight the metallic luster. The style is classic and minimalist, likely dating from the 1970s to 1990s, showcasing a handmade aesthetic rather than a mass-market finish.
