Gold-toned adjustable bypass ring and stud earrings set

This jewelry collection features a gold-toned adjustable bypass ring and multiple pairs of stud earrings. The bypass ring is characterized by its open-ended shank, allowing for size adjustment, and features two distinct terminal designs: one side showcases a central round-cut clear stone surrounded by a fixed halo of smaller stones in a floral or sunburst motif, while the other side ends in a singular bezel-set round stone. The metal exhibits a warm golden hue, likely gold-plated or costume-grade base metal, showing signs of tarnish and darkening, particularly in the recessed areas of the settings. Accompanying the ring are four stud earrings featuring clear round-cut stones secured by four-prong basket settings. These stones appear to be glass or cubic zirconia rather than diamonds, given the lack of specific refractive brilliance under the lighting. The earrings include metal friction backs (butterfly backs). Visible condition issues include significant oxidation and patina on the earring settings and some minor surface scratching on the ring band. The overall design suggests contemporary retail origins, likely late 20th to early 21st century, mass-produced for the fashion jewelry market. Craftsmanship is standard for commercial costume jewelry with visible solder points and slightly irregular prong placement on the studs.
