Oval Ruby and Diamond Bypass Ring in White Gold

This elegant cocktail ring features a prominent oval-cut natural ruby as its centerpiece, displaying a deep magenta-red hue. The ruby is securely set in a four-prong mount within an intricate bypass-style frame. The setting consists of two sweeping bands of white gold that curve around the central stone; one band is channel-set with graduated baguette-cut diamonds, while the opposing band features round brilliant-cut diamonds. This combination of diamond cuts provides a sophisticated contrast in brilliance and texture. Based on the styling and mount construction, this piece likely dates from the late 20th century, specifically the 1980s or 1990s. The metal appears to be 14k or 18k white gold, showing high-reflectivity and a classic bright finish typical of rhodium plating. Visible condition is good, with some minor surface scratches on the band consistent with wear. The craftsmanship is high, evidenced by the seamless channel setting and the symmetry of the bypass design. No specific maker's marks are visible in the provided image, but the overall stone density suggests a fine jewelry retail background.
