Type
Jewelry (Brooch/Pin)
Maker
Unidentified workshop; likely a commercial jeweler from the early 20th century. High-volume production for the middle-market, common in the US or UK.
Material
Likely Sterling Silver (.925) or 800 Silver, heavily tarnished. Base metal is likely silver, though the yellowish hue in localized areas may suggest vermeil (gold wash) or nickel-silver base if plate.
Dimensions
Approximately 2.5 cm (1 inch) in diameter. Estimated weight: 3-5 grams. Small scale designed for lapel or scarf wear.
Description
This small, circular silver brooch showcases the transition of early 20th-century design into the Art Deco period. Featuring a central void surrounded by a concentric frame of geometric piercings, the piece utilizes negative space to create a light, architectural feel. The reverse shows a standard safety pin mechanism, while the heavy tarnish suggests a high silver content that has reacted to the environment over several decades.
Key Features
Circular openwork design, architectural bridge-like piercing, 20th-century rolling safety catch, and distinct geometric symmetry.
Material & Composition
Likely Sterling Silver (.925) or 800 Silver, heavily tarnished. Base metal is likely silver, though the yellowish hue in localized areas may suggest vermeil (gold wash) or nickel-silver base if plate.
Finish & Decoration
Aged, high-sulfide tarnish (patina). Decorative technique is machine-piercing or die-stamping with geometric cut-outs. Style is late Art Deco, moving toward minimalist modernism.
Hallmarks & Stamps
No visible marks in the provided image. Common locations for this type would be on the reverse rim or the pin stem, often '925' or 'STERLING'. Absence of hallmarks on small pieces often suggests lower-tier manufacture or wear.
Construction Details
Die-stamped from a thin silver sheet to create openwork; a separate pin assembly consisting of a hinge and a 'C' clasp or safety catch and stem has been soft-soldered to the reverse.
Functional Features
Horizontal rotating safety catch mechanism; hinge with pin stem. Designed for attachment to textile.
Handle & Grip Details
Simple brass or silver-plated pin stem; functional rather than decorative grip. Clasp shows a rolling lock common after 1910-1920.
Craftsmanship Details
Medium quality. Die-struck for speed and consistency rather than hand-wrought. The soldering of the pin back is functional but lacks the refinement found in higher-end boutique silver pieces.
Authentication Indicators
Construction method (die-stamping) is consistent with mass-market Deco jewelry. Patina is deep and characteristic of old silver. Clasp style matches the purported 1920s-30s era.
Origin & Manufacturing
Likely American or British. The manufacturing style is industrial, indicative of the jewelry manufacturing hubs of Providence, RI or Birmingham, UK.
Era & Period
Art Deco (1920–1940). Indicators include the strict geometric symmetry, pierced architectural lines, and the specific style of the safety clasp.
Age Estimate
Circa 1925–1935. Based on the mechanical safety clasp and the transition from elaborate Art Nouveau to structured geometric Deco patterns.
Cultural Significance
Represents the democratization of luxury; as jewelry manufacturing became more industrial, middle-class women could afford silver pieces that mimicked the high-end platinum 'white' looks of the era.
Condition Notes
Good to Fair. Heavy oxidation/tarnish covers the entire surface. No missing structural elements but significant surface grime. Pin stem appears slightly bent. Grade: Good (Antique/Vintage).
Value Estimate
$20 - $45 USD. Value is based primarily on aesthetic appeal and metal content rather than maker prestige, as it is an unsigned commercial piece.
Care & Maintenance
Clean with a soft brush and mild soap to remove surface grime. Follow with a silver polishing cloth or Wright's Silver Cream. Avoid chemical 'dips' which can be too aggressive on delicate pierced work.
Similar Pieces
Pastel enamel Art Deco pins (similar size but different finish) or high-end Cartier/Tiffany pierced platinum pins (which this piece commercially imitates).
Interesting Facts
During the Art Deco period, pins like this were often worn in multiples or to secure the 'cloche' hats popular during the flapper era. Geometrically designed jewelry was a reaction against the flowing, organic lines of the previous Art Nouveau movement.
