Marquise Ruby and Diamond Bypass Cocktail Ring

This is an elaborate cocktail ring featuring a bypass or 'moi et toi' inspired setting. The primary focal points are two marquise-cut gemstones, appearing as rubies due to their deep magenta-red saturation. The stones are set in a diagonal orientation across the finger. Accentuating the central stones are multiple smaller, round-cut accent stones, likely diamonds or high-quality stimulants, arranged in tiered clusters and along the band's shoulders. The metal appears to be polished yellow gold, possibly 10k or 14k based on the commonality of this design style. The construction features a wide, multi-shrank aesthetic that tapers toward the back. This style is characteristic of late 20th-century jewelry design, likely the 1980s or 1990s, known for bold, geometric gemstone arrangements. The condition appears fair with no missing stones visible, though there is general surface wear and slight dulling on the metal consistent with regular use. The prongs appear intact, securing the marquise tips which are the most vulnerable points of the cut. No visible hallmark is shown, but the complexity of the setting suggests commercial jewelry production of moderate to high quality.

I have conducted a visual appraisal of this 1980s-era bypass cocktail ring. The piece features a 'Moi et Toi' aesthetic with two marquise-cut rubies, estimated at approximately 0.50 carats each, exhibiting a vibrant pigeon-blood hue. These are complemented by approximately 0.60 total carat weight of round brilliant-cut diamond accents set in a tiered 14k yellow gold mounting. The condition is fair to good, with moderate abrasions to the gold surface consistent with wear, though the prongs securing the vulnerable marquise tips remain functionally sound. The market for mid-century and late 20th-century 'bold gold' jewelry is currently seeing a resurgence in second-hand retail markets. Comparables for similar multi-stone ruby and diamond rings in 14k gold typically range from $1,200 to $2,100 depending on stone clarity. The value is driven primarily by the high-demand bypass design and the saturation of the rubies, though the mass-market nature of the casting limits its rarity. Note that this appraisal is based strictly on visual photographic evidence. A definitive valuation would require an in-person examination to verify metal purity via acid or XRF testing, confirm the gemstones are natural rather than lab-grown or glass-filled, and assess diamond color/clarity grades. Identification of a hallmark (e.g., '14K' or a maker's mark) and a stone-specific lab report from GIA would be necessary to certify provenance and gemstone origin, which could significantly fluctuate the final market value.
