I heard that it takes marbles greater than 8" before you can tell how fully develope marbling can look so i just wanted to see if these would be, these only four months at about 6-7 inches....Any input would be great.
Think this would be just about impossible. Most marbles dont develop there marbling till they get over 8" so what would you do have a rating system for rays under 8" and another for over 8"?
