Marquise Sapphire and Diamond Bypass Halo Ring

This is a contemporary bypass-style ring set in yellow gold, likely 10k or 14k based on common commercial jewelry standards. The centerpiece features two marquise-cut gemstones positioned in a diagonal bypass orientation. These stones appear to be dark blue sapphires, characteristic of the 'midnight blue' variety often sourced from Australia or Thailand. Each sapphire is secured by six prongs within a shared halo setting comprised of approximately 14 small round accent diamonds or stimulants (such as cubic zirconia). The halo follows a tiered, serrated edge motif. The ring's band or 'shank' features a split-shoulder design that flows into the bypass arrangement. The color of the yellow gold appears bright, though there is a noticeable dulling on the prongs and some buildup or dirt beneath the stones, which is typical for pre-owned jewelry. The facets on the sapphires show minor signs of surface wear, suggesting it has been worn regularly. The craftsmanship is consistent with late 20th-century mass-market fine jewelry (circa 1980s-1990s). Measurements are not provided, but the scale relative to the finger suggesting a standard woman's ring size between 6 and 7.
