Vintage English Crown China Crafts Flowers Brooch

Pretty vintage floral brooch. I’m not sure what the flower is, maybe pansy or primrose. One blue, one purple, and one pink, with green leaves. Some smaller flowers underneath. Likely hand-painted bone china or ceramic, but I’m not 100% sure. 1940s or 1950s. Made in England. Marked MILL ST STOKE See images for further details and measurements. From a smoke free and pet friendly home.
