Bill Burchfield of Cape Cod Glass is more known for his furnace made paperweights, but every once in a while he made some gorgeous little marbles, usually featuring pretty cane inside. He's not making them any more, so they're VERY hard to come by. I've never sold any of his little gems like this one because they're all just SO dang beautiful, and REALLY hard to let go of. They've almost always got some sweet sparkly goldstone like this one does, and this one has it both in the core (on the backside of the red cane) and in faint sweet bands on the edges of the twisted blue outer cane. It's a complex little zinger, so wonderful! Cape Cod's marbles have been highly prized over the years and are very collectible, so you'll definitely want one of these pieces in your collection, rare chance here!
