Authentic Art Deco T & G Rhinestone Brooch Blue Sapphire Clear Glass Bow Pin Geometric Pot Metal 1920s 1930s

Authentic Art Deco design, bold architectural geometry, and exceptional visual presence define this striking vintage T & G rhinestone brooch. Executed in an elegant bow-inspired geometric form, the design combines vivid sapphire-blue and brilliant clear glass rhinestones within a carefully balanced composition that captures the glamour and sophistication of the late 1920s through early 1930s. The crisp rectangular forms, symmetrical layout, and restrained color palette are quintessential Art Deco.

Rather than lying flat, the brooch is engineered with a gracefully arched center that creates depth and allows light to play across the rhinestones from multiple angles. Rich sapphire-blue square-cut stones form dramatic borders at each end while a matching blue center panel visually anchors the composition. Rows of sparkling clear rhinestones framed by delicate milgrain edging create strong horizontal bands that reinforce the streamlined architectural styling. The dimensional profile gives the brooch a sculptural quality that is often absent from flatter examples of the period.

Measuring approximately 3½ inches long by 1⅜ inches wide and weighing an impressive 35 grams, this is a substantial Art Deco statement piece with excellent craftsmanship. The reverse is marked "T & G" and retains its original pin assembly. Constructed in pot metal, the brooch remains remarkably clean for its age with crisp cast details and very little of the corrosion often encountered in early pot metal jewelry.

The sapphire-blue rhinestones retain excellent color, brilliance, and overall condition. Several of the clear rhinestones have developed a soft champagne tone from natural age-related foil mellowing, while others remain bright and clear, creating the warm character expected of authentic Art Deco costume jewelry approaching a century in age. This subtle variation is visible upon close inspection and does not detract from the brooch's striking overall appearance. The piece has been left unpolished to preserve its authentic vintage character.

An outstanding example of early Art Deco costume jewelry, this T & G brooch will appeal to collectors of geometric rhinestone jewelry, architectural design, blue and clear crystal brooches, and fine examples of late 1920s and early 1930s American costume jewelry.
