Mixed Collection of Sapphire Rings and Loose Gemstones

A varied collection of jewelry and gemstones featuring two rings and two loose stones. The first ring is a halo-style design featuring an oval faceted dark blue sapphire centerpiece, approximately 1.5 to 2 carats, surrounded by a border of small clear accent stones (possibly diamonds or white sapphires) set in a white metal band. The second ring features a blue cabochon sapphire with possible asterism (star effect) or Chatoyancy, set in a vintage-style decorative white metal mounting with ornate gallery work. The loose gemstones consist of one oval-facet emerald, displaying a rich green hue with visible natural inclusions typical of the species, and one oval-facet dark blue sapphire. The metal appearances suggest a mix of white gold or sterling silver, and one yellow gold band is partially visible on the finger. The blue stones exhibit a deep, saturated navy tone. Condition appears fair to good; the loose stones show typical facet wear, while the rings exhibit light surface scratches and patina on the settings consistent with moderate use. The craftsmanship of the halo ring suggests contemporary manufacturing, while the cabochon setting appears more classic or mid-20th-century in style. The presence of natural inclusions in the emerald and the color saturation of the sapphires are significant quality indicators for future gemological testing.
