This vase is so unique! I have held onto it, because I have not found anything like it in my research. This has a grainy texture on the bottom almost like stoneware. The sides have a scale like textured to them and are glossy. The bottom is signed (Nanette?). Possibly arts and crafts pottery? I am obviously no expert on pottery and vases, but this is such a unique piece.

If you see something glaringly wrong with my listing, please feel free to let me know. I am always happy to learn more.
