JOSEPHS COAT SWIRLS

Josephs Coat Swirls possess subsurface multicolored strands placed very close together, though sometimes there are open areas that allow the interior of the marble to be viewed. Some of the strands may go deeper into the glass, often to the core. The colors of the strands may be very bright or more earth-toned, and the base glass may be clear or less frequently colored, usually light or pale blue. There may be many different colors in the strands or as few as two. It is uncommon, but Josephs Coat Swirls may also contain aventurine.
