Large Flower Bouquet Reverse Carved Brooch Pin Vintage

This beautiful brooch offers a vibrant bouquet with roses, yellow flowers and greens, surrounded by a clear outer edge. It is thick, yet lightweight. I believe it is lucite material. Some surface scuffs. See pictures. It appears part of the original tag is still present. The brooch is nearly 2 1/4" wide. Questions welcome. From a smoke fee home.
