Nina's marbles were sold back in the early 2000's under her studio name, California Glass, but Nina is the brilliant artistic mind behind these fun marbles. Her marbles are furnace made, and always heavily utilize gorgeous dichro pieces, usually layered in amazing ways like this one. This one is triple layered - for you boro collectors out there, imagine a Badback (Daschbach) marble and all the layering he does with his designs. Same concept here, just dipped in the furnace to get the layers of clear before more dichro pieces are added. The result is FANTASTIC and SOOOO dang fun to explore. This is one the nicest I've seen, hard to let go of. Don't miss this killer slice of marble history!! Signed 'NP'.
