Bought this marble with a few other old marbles. It’s base seems to be transparent red on one side and transparent blue on other side. It has opaque yellow and white glass flowing through it. I think the transparent colored glass makes it seem like it is very colorful. The glass is textured like a handmade German. Size is just under 1 1/4 inches. Bought a green mica, a blue dyed agate, green dyed agate, purple Popeye, a parrot and a few other old marbles with it so I think it is old. Any idea on what it is or when made or by a certain company would be appreciated.
