Sapphire and Diamond Sunburst Stud Earrings

This pair of stud earrings features a classic sunburst or halo design. Each earring is centered with an oval-cut dark blue gemstone, appearing to be a sapphire, estimated at approximately 0.50 carats each. The center stone is surrounded by a radiating halo of ten small round-cut accent stones, likely diamonds or high-quality cubic zirconia, set in individual yellow gold prongs. The mountings are crafted from yellow metal, presumably 10k or 14k yellow gold given the style, though no hallmarks are visible in the image. The construction utilizes a traditional post-and-butterfly backing, currently shown with clear plastic comfort clutches. The craftsmanship displays vintage characteristics consistent with jewelry from the late 20th century, approximately 1980-1990. The overall condition appears fair to good; there is some visible debris or oxidation around the prongs that may require professional cleaning. The stones appear securely set, though the clarity of the accent stones suggests they are either heavily included diamonds or synthetic stimulants. The dark, 'inky' blue of the main stones is characteristic of sapphires from specific regions or those that have undergone heat treatment. The earrings measure approximately 8mm by 10mm.
