Antique Czech Uranium Glass Pendant Art Nouveau Brass Filigree Gold Filled

Vintage Czech Uranium Glass Pendant - Early Art Nouveau/Deco Brass Filigree - Circa 1910s-1930s - Gold-Filled Finish

This exceptional antique pendant features a large uranium glass cabochon that glows a vivid neon green under UV light — a hallmark of early Czech/Bohemian uranium glass from the 1910s-1930s. The cabochon is smooth, domed, and beautifully translucent, showing the strong fluorescence highly prized by collectors today.

The ornate setting is crafted from solid brass, not modern brass-tone. The detailed filigree scrollwork, floral accents, and raised decorative elements display the hallmarks of hand-finished early 20th-century craftsmanship, typical of Czech and Austro-Hungarian jewelry workshops.

Metal testing confirms a gold-filled or heavy gold-wash surface layer:

• 14k acid dissolved

• 10k & 9k acids did NOT dissolve

This result is consistent with genuine lower-karat gold applied over brass, which was common in quality early Czech filigree work.

Hand-soldered joints, natural aged patina, and the depth of the casting all verify this piece as an authentic early 20th-century Art Nouveau to early Deco pendant — not a reproduction.

Large uranium glass pendants in original brass filigree mounts are significantly rarer than brooches, making this a scarce and desirable collector's piece. A complementary gold-tone chain is included, allowing it to be worn immediately.
