SUBMARINES

Submarines are difficult to classify but seem best suited to the category of Transparent Swirls. These are marbles that superficially resemble Paneled Onionskins. However, two opposing panels of color will have colored bands on the surface of the marble, which has a transparent base that is usually blue, green or clear. The other two panels, which fill in the space left by the two surface ones, will have colored bands under the surface. It is this alternating surface/subsurface paneling that defines the Submarine. These marbles are rare, and those with mica in the clear panels are rarer still.
