Female Dancer Balancing a Ring Lamp

This has been my favorite lamp of all time. She was an incredible Art deco Dancer balancing a large metal ring in one hand. Her leg was pointed up holding up the shade. There is no marking on the bottom but has green felt. I believe it's made from some type of hard plastic or resin material. As you can see it has been broken and I have to replace it. I've looked on line but have not seen any lamps like it. Thanks so much for any help.
