A unique marble from this consignment collection. Unusual baby blue and translucent gold surface bands with a ribbon core My esteemed and very knowledgeable consignor had this labelled as an End of day, English Style Panelled Submarine type. I believe all of these factors to fit in. Short form, it's a type of banded transparent with surface bands. I've never seen that gold jelly colour before. It's truly spectacular No damage but a few notable asmades.. A larger pullout and oval pops. Without those, this marble would fetch a great deal more, however, you may be hard pressed to ever find one like this again.
