Vintage Czech? Filigree Multi Color Crystal Pin Brooch

Vintage unsigned Czech? filigree multi color crystal pin brooch. Given the construction and design of this piece, Google Lens tells me this is likely either Czech or Austrian in origin. Antique gold tone filigree multi-layer design with crystals in red, blue, green. pink and yellow. Clasp works fine. See photo for size. Pre-owned. Please ask if you have questions.
