I'm certain this is a Murano piece, but I am stumped as to specific maker. It has a squat profile, flat windows, flat base and is almost 4 inches in diameter. The overlay is a deep rosy shade of red. The photos give it a warmer cast than it actually has.
The weight has a fake Baccarat mark that I could not get to show in the photos.
I saw another weight like it up for auction that had a blue overlay.
