I’m thinking Vitro. If you back light it and the base glass is purple or blue that’s where I’m going with Vitro. Also the ribbons look veneered instead of continuing into the matrix.
Yours doesn’t have the vertical and offset horizontal seams like you see in the examples above. Yours has that V pull that screws up the seam configuration which I think makes it HTF 👍
This one is a 3 inch monster. I have a few ideas of what it might be. Part of a lamp or bed post. It was a true flea market find and was in a box of rocks.
