This is a Vintage Orchid Flower Brooch Herringbone Gold-Tone Brooch. Brooch measures approximately 2" in length. It is Unsigned / unmarked and its origin / creator / year of manufacture are all unknown. I would guesstimate that it is from the 1970s-1990s, but it's also just as possible that this is a modern piece done in retro style. The gold-tone metal has a pattern that I'm calling "herringbone" - it creates depth and slight texture. Brooch is shaped like an orchid and it is possible that there was once a gemstone or something else inside the open bloom, but there is nothing there now. That said, the brooch is in gorgeous condition with no discernible flaws and no signs of wear/age. ***Please note that many of the images you see were taken with a macro filter on the camera to provide close-up detail. This makes the size of the pin in the photographs somewhat misleading, so DO CHECK THE MEASUREMENTS to get a better sense of its size.
