Vintage 14k Gemstone Flower Brooch Signed Amethyst shops Garnet Citrine

Product Name: Vintage 14k Gemstone Flower Brooch Signed Amethyst shops Garnet Citrine
vintage 14k yellow gold brooch with amethyst, citrine, and garnet gemstones. it is marked shops 14k on the back and on the clasp and there's also a hallmark which looks like a little house. I am not sure who made it based on that stamp but it looks to be of a better quality. the brooch measures 1.5" long. it does have a loop on the back of the amethyst stone so it can be worn as a pendant on a necklace chain if desired.
