Hi everyone

I need help identifying this alexandrite glass pitcher I bought at a flea market...I went through Moser, Heiney, Steuben, Cambridge, Tiffin, Fostoria and Bohemia alexandrite items but I can't find any pitcher or other glass piece that resembles my pitcher's manufacturing technique. I'm including some pictures of the pitcher both in incadescent and fluorescent light. It's dimensions are -approximately- 21cm (wider point diameter), 12cm (bottom diameter) and 24.5cm (height). There are no mold marks (it's indisputably handmade), and I can't find a signature anywhere.
I'm guessing it's a rare piece since days of meticulous search haven't yielded any results... I'm counting on the experts now!
Thank you!
