1920s - 30s vintage green glass cake stand, with wheel cut or etched pattern, encrusted gold border. I believe this is one of Tiffin's many patterns that were numbered, without 'real' names. Lovely teal color and the border look very typical of older Tiffin glass to me.
This measures about 11" overall diameter, stands about 21/4" tall. It's been used and loved, and has noticeable wear to the gold trim, scratching and utensil marks to the surface of the plate.
