Designer: Florenza, signed on the back of the piece.

Era: Mid-20th century (approximately 1950s-1970s), when Florenza was known for its intricate designs and quality craftsmanship.

Material: The metal setting has a black rhodium finish, which gives it a rich, gunmetal gray color and provides a dramatic contrast that makes the stones "pop". The brooch is adorned with various glass stones, including pink and blue rhinestones and a prominent blue-hued "lava glass" cabochon. Lava glass, or volcanic glass, has a porous, textured surface that gives it a unique earthy and rustic look
