Up for sale is an exceptionally rare, museum-grade piece of signed American Art Deco estate jewelry. This functional quizzing glass magnifier pendant features a heavy, solid 14-karat white gold framework beautifully styled with the tailored, geometric lines characteristic of the high Art Deco movement.
KEY OBJECT METRICS:Composition: Confirmed Solid 14K White Gold FrameProvenance: Signed Dinhofer Bros. Jewelry Co. (Historic New York City Workshop).
HISTORICAL PROVENANCE & MARKS:The side collar structure of the frame is clearly hand-stamped with the traditional gold purity hallmark "14K". Immediately preceding the gold purity stamp is the plain-text "extended-bar D" maker's mark used by the elite New York goldsmithing firm Dinhofer Bros. following the landmark National Gold and Silver Stamping Act of 1906. The handle showcases a gorgeous, pristine geometric pierced filigree openwork design, making it a spectacular, wearable statement piece when paired with a fine neck chain or pocket watch vest chain.
OPTICAL CONDITION REPORT: The heavy, thick convex optical glass lens is in pristine, museum-grade condition. For an authentic utilitarian object dating from the 1920s, it is incredibly rare to find a specimen completely free of surface scratches, internal clouding, or typical "flea-bite" rim chipping. The magnification is exceptionally sharp and highly functional for reading fine print, maps, or programs.
