Someone in Georgia contacted me for help IDing this article. Does not look familiar so I am giving you bunch a try at helping

He reports:
Found in Georgia at an Estate Sale amongst many other antique/vintage items being sold. (Some other knob/tube insulators were at the house too, so that was my first guess, but I'm coming up short on finding a match
His description:
Amber glass with mold lines on each side. About a “honey amber” shade.Lots of bubbles.Length about 3.75”Width just over 1” at the widest pointEnds ground flat.I don't recognize it. Looks decorative, the sort of colored glass bit that someone might save when something larger has reached the end of its life and is scrapped/disassembled, part of a lamp maybe.
