rindge Posted March 12, 2010 Report Share Posted March 12, 2010 This over 2" swirl marble has a large transparent fat core. In normal light you can make out barely visible lines of a core. When backlit or held to the light there is a distinct tiny bubble filled fat core. The bands are blackish purple. There is a large ground pontil on top and maybe a smaller one on base. Is there such as a thing as a ghost or clear core marble. Thanks for looking. Rindge. Link to comment Share on other sites More sharing options...
