jeroen Posted February 15, 2014 Report Share Posted February 15, 2014 Hi, This one came with the post yesterday. It is a kind of ribbon core. About 7/8 inch. one ribbon is a kind of jelly transparent glass, the other is from many thin black lines. It has some mica in it too. Near the pontil are some small flakes, and opposite of the pontil a few bigger flakes. They can be seen in the lower right photo, and the lower middle photo. It has a facted pontil, and glows under a black light. So what kind of marble is this? Link to comment Share on other sites More sharing options...
