Michal Golan Gold Toned & Green Stone 1.5 inch Brooch

Michal Golan is a New York based fine jeweler. She does use real stones, crystals and beads, as well as gold over electroplated brass. However, I cannot find any information about this piece and therefore cannot confirm the brooch's materials. Excellent condition. Gold toned hardware, green stones with decorative florals and swirls. Pin and signature at back. 1.5 inches long.
