Sapphire and Diamond Channel-Set Eternity Band

This item is a contemporary-style eternity or wedding band featuring a channel setting. The band appears to be constructed from 14k or 18k yellow gold, though a white metal plating or a two-tone effect is visible on the upper rails where the gemstones are seated. It is set with alternating round-cut natural blue sapphires and colorless diamonds. The sapphires exhibit a deep, royal blue hue, while the diamonds provide a bright, high-clarity contrast. The channel setting is smooth and flush, a hallmark of mid-to-late 20th-century jewelry design, intended to protect the stones from daily wear. The metal surfaces show minor surface scratches and faint abrasions consistent with regular use, but no significant structural damage or missing stones are observed. The band has a uniform width of approximately 3mm to 4mm. While no maker's marks are visible in the provided image, the precision of the stone alignment suggests professional craftsmanship. The style is timeless, likely dating from the 1990s to the present. Quality indicators include the consistency of the gemstone color and the evenness of the channel metal borders.
