Vintage Art Nouveau Tiffany Style Shade

Tiffany, Steuben, Durand, Quezal?? Art glass shade. Its absolutely gorgeous! Gold Aurene on the inside & calcite on the outside with gold threads. 1905-1924 the luster on the inside and outside is so beautiful, it has a tiny flea bite on the inside it looks like a little popped air bubble it does not go through(see photo) the threads are in perfect condition no missing pieces. It's unbranded (I couldn't find a hallmark) and the small opening has a tiny bit of roughness around the edge(see photo) Its a perfect example of early 20th century art glass. Please see photos for details and measurements
