I assume that yours is blue and green.
Here's another odd one,the base is wine red and the colors are tan-brown and blueish but I think the blueish color is actually white.
Unfortunately it is damaged,oh and the cut-off is a straight line.
I'm not sure if this one is Japanese,might be made somewhere else?
The longer I look the more I think about Japanese patches,they also come in clear glass.
Those patches can be confusing,I'm happy to know that I'm not the only one that struggle with them LOL
Yes in the wild but not at the same time and Always in old marble groups.
I like some of the old Japanese patches very much.
here's another one,looks a bit like Pelt but is Japanese.
I've looked in my boxes,and boy that was fun,was forgotten how nice some of them are.
Not quite what you asked,4 vanes,each vane has 2 colors,2 red vanes with a little blue and on the other side 2 blue vanes with a little red.
Yes the mushroom types and other patches,the transitionals and fig8 types,for me everything indicates that these marbles are made before the second world war.
