Mixed-Metal Marquise Ruby and Diamond Filigree Wide Band Ring

This is a contemporary wide-profile cocktail or fashion ring featuring a two-tone metal construction, likely 14k or 18k yellow and white gold. The central focal point is a bezel-set, marquise-cut ruby of a deep pigeon-blood red hue. Surrounding the center stone is an intricate openwork filigree design consisting of scrolling floral and vine motifs in white metal, accented by several small round brilliant-cut diamonds. The borders of the ring are wide yellow gold bands featuring pav -set melee diamonds and fine milgrain edging, which adds a vintage-inspired or Edwardian-revival aesthetic. The craftsmanship displays high attention to detail, particularly in the symmetry of the scrolling wirework and the precision of the milgrain. While the overall condition appears excellent with no visible missing stones or significant scratches on the metal, the dark red ruby shows characteristic saturation common in quality natural stones, though lab-grown origin cannot be ruled out without magnification. This piece combines Art Deco geometric structure with romantic curvilinear flourishes, making it a sophisticated example of modern high-end bridge jewelry.

I have conducted a visual appraisal of this mixed-metal marquise ruby and diamond filigree band. The ring exhibits high-caliber craftsmanship indicative of custom or high-end bridge jewelry, blending 14k/18k yellow and white gold. The central marquise ruby, estimated at 0.80-1.00 carats, displays the highly desirable 'pigeon blood' saturation. The surrounding openwork filigree and milgrain detailing are consistent with Edwardian-revival styles, featuring approximately 0.50-0.70 total carat weight in round brilliant-cut diamonds. The piece is in excellent condition with no visible wear to the prongs or milgrain. In the current market, vintage-aesthetic contemporary pieces command a premium due to the labor-intensive nature of the metalwork. Comparable sales for two-tone designer filigree rings often fall within the $4,000 to $7,000 range depending on brand provenance and stone origin. However, several factors limit a definitive valuation from images alone. A physical inspection is required to determine if the ruby is natural, heat-treated, or lab-grown, which could fluctuate the value by 40-60%. Furthermore, I cannot verify metal purity stamps or diamond clarity/color grades without a loupe. Full authentication would require GIA certification for the ruby to confirm its geographic origin and treatment status, as well as a professional stone-setting check to ensure the integrity of the pavé work.
