Yellow Gold Ruby and Diamond Band with Arthritis Shank

This is a detailed ring featuring a yellow gold band with alternating sections of red gemstones, likely rubies, and small white clear stones, likely diamonds. The band is approximately 3-5mm wide at the top, tapering slightly toward the base. The rubies are channel-set in rectangular or square cuts, displaying a deep pinkish-red hue. Interspersed between the ruby sections are round-brilliant or single-cut diamonds pavé-set in white metal or bright-polished yellow gold to maximize brilliance. A highly notable feature of this piece is the hinged 'Finger Fit' or similar adjustable arthritis shank. This mechanical feature allows the ring to open and close over an enlarged knuckle, indicating a custom or high-end modification for comfort. The metal shows minor surface scratches consistent with light wear, and the hinged mechanism appears functional. The style is indicative of mid-to-late 20th-century fine jewelry, likely from the 1980s or 1990s. While no hallmarks are clearly visible in the image, the craftsmanship suggests 14k or 18k gold construction. The combination of channel and pavé settings reflects high-quality labor and a classic aesthetic.

Based on my visual analysis of this yellow gold ruby and diamond band, I estimate its replacement value at $1,800 to $2,400. The piece features a high-quality channel setting of square-cut rubies alternating with pavé-set diamonds, a classic late-20th-century design. A significant value-add is the 'Finger-Fit' style adjustable arthritis shank. These mechanical shanks are expensive custom additions, typically costing $500–$800 for the part and labor alone, and they significantly increase the secondary market appeal for buyers with similar accessibility needs. The rubies exhibit a desirable pinkish-red saturation, while the diamonds appear to be well-matched in color and clarity. The condition is excellent, showing only light surface wear on the high-polish gold. Market demand for high-end 'solution' jewelry remains steady, particularly for 14k or 18k gold pieces with functional mechanisms. However, there are significant limitations to this remote appraisal. I cannot verify metal purity hallmarks or the natural vs. synthetic origin of the gemstones via image alone. A full authentication requires an in-person physical inspection to test the metal's acid or XRF reaction, a microscopic exam to check for inclusions indicative of natural versus lab-grown rubies, and a gemstone weight estimation. The presence of a jeweler's hallmark would also provide a more definitive provenance. This valuation assumes the stones are natural and the gold is at least 14k.
