New Members Rogerhd Posted May 26, 2013 New Members Share Posted May 26, 2013 I found this rock in the field here in Illinois. It is very heavy. It broke open & the inside is silver in color w/a mix of quartz. It is not magnetic. Thanks Roger Link to comment Share on other sites More sharing options...
