Edwardian Style 18k White Gold Filigree Diamond and Sapphire Ring

This is an exquisite example of an Edwardian-style filigree ring, likely dating from the 1920s Art Deco transition period or a high-quality vintage revival. The ring is constructed of 18k white gold, weighing 4.8 grams, and features an intricate openwork filigree design with floral and scroll motifs. At the center is a prominent round brilliant or transitional cut diamond, estimated at approximately 0.75 carats (3/4c), securely held in a hexagonal illusion setting that maximizes its visual presence. The diamond exhibits high brilliance and clear facet definition. Flanking the center stone are two round faceted blue sapphires, each set into smaller hexagonal collets, providing a striking color contrast against the white metal. The filigree work shows expert craftsmanship, characterized by fine milgrain edging and delicate metal lacework throughout the elongated navette-shaped gallery. The ring is a size 6.5. Condition appeared to be excellent, with the metal maintaining a high-polish finish and no visible breaks in the delicate filigree. The stones appear securely set with no obvious chips or abrasions visible to the naked eye. The substantial gram weight of 4.8g for such a delicate-looking piece indicates high-quality solid construction typical of fine jewelry from the early 20th century.

Based on my visual examination of the provided images, this ring presents as a high-quality example of Edwardian-style fine jewelry, likely dating to the early Art Deco period (circa 1920s) or a very fine mid-century revival. The 18k white gold construction (at a substantial 4.8g) and fine milgrain detailing speak to superior craftsmanship. The central diamond, estimated at 0.75 carats, appears lively with characteristics consistent with a Transitional or Old European Cut, which are highly desirable in today's vintage market. The filigree work is intricate and well-preserved, showing no obvious breaks in the metal lacework, which is critical for resale value. The inclusion of synthetic sapphires was common in genuine Art Deco jewelry; however, without gemological testing, I cannot determine if these side stones are natural or synthetic, which would impact the upper end of the valuation. The market for authentic Edwardian and Art Deco bridal jewelry remains robust, with strong demand for "navette" shapes and mixed gemstone designs. Critically, a definitive appraisal is limited by the lack of physical inspection. To confirm the top tier of this value range, I would require in-person verification to: 1) grade the diamond for color and clarity (assumed closer to G-H/VS for this estimate), 2) verify the sapphires are natural utilizing refractive index testing, and 3) confirm the "18k" stamp authenticity against metal purity testing. Assuming natural stones and VS2/SI1 diamond clarity, the value is solid. If the piece is a modern reproduction rather than true vintage, the value would adjust downward to the $1,200 range.
