Two pieces going out together, a brooch and a second piece that works as a pendant, a scarf slide, or a small buckle. Both are set with glass stones that light up under UV, and neither carries a maker's mark. That bright green response is the signature of uranium glass, which the Bohemian and Czech houses used constantly, and it's the single most collected thing about jewelry like this right now! They'd be gorgeous worn as a set, layered into a brooch stack, or pinning a velvet jacket, a hat, or a shawl. Perfect on a blacklight display shelf with other glowing glass, and made for Halloween styling, festival wear, and any photo where you want something that transforms when the lights change. Pendant or buckle piece 1.25" long, brooch 1.5" long. Both have wear. The center of the pendant piece is the fun mystery: iridescent with a swirl, definitely not mother of pearl, and it glows bright, which argues glass over lucite or resin, though I won't name it beyond that. There's a glow along its sides too that's most likely old adhesive. See photos for exact condition. Note: Untested, as is, as seen, no guarantees. As a found vintage item, there may be wear, dust, and other callouts I miss.
