18 Karat White Gold Vintage Art Deco Rose Cut Diamond Collar Necklace

A striking Art Deco collar necklace in solid 18 karat white gold, set throughout with rose-cut diamonds. The rose cut’s defining geometry—domed crown of triangular facets converging at a central apex over a flat base—creates a broad face-up presence with refined, antique-style scintillation that suits the clean, linear character of a collar silhouette. The bright, neutral hue of 18k white gold amplifies the diamonds’ surface light while maintaining a slim, low-profile look characteristic of the period. Designed to sit close to the neckline, the collar format delivers a continuous, even line of sparkle with a distinctly Deco sensibility. Material composition is 18k white gold with rose-cut diamonds; stone color and clarity are not specified. The technical pairing of rose-cut facet architecture and a structured collar layout underscores precise period styling and enduring craftsmanship.
