Kramer of New York vintage brooch features a stunning cluster of aurora borealis and smoky topaz glass stones in a variety of cuts, including teardrop, marquise, and round. The gold-tone setting provides a warm base for the iridescent AB finish, which reflects a vibrant spectrum of blues, greens, and purples against the earthy amber tones. This mid-century piece is ideal for collectors of high-end costume jewelry or anyone looking to add a touch of regal elegance to a lapel, scarf, or evening gown.
