I haven’t come across one quite like it but with the hole in the bottom it must have been made to sit in a vase and support flowers. There are many different types some of glass, ceramic, wire, plastic. Some are really beautiful. This one doesn’t have a makers name. It is in good used vintage condition. There is a tiny area where a bit glaze has come off next to one of the holes.
They make an unusual item to collect and one can still find them at garage sales and auctions at a good price. They were extensively used until the early 50’s when “oasis” took over. Dont hesitate to contact me if you you have any questions.
