A stunningly beautiful example of Nowak's extra large size tubular reef marble. I LOVE the colors in this one, so so beautiful! This one has an unusual tubule on it which you can see on the right of the 4th picture - pure dichro with clear glass, VERY cool. These marbles are wildly sought after and were only sold by me, no longer made and long since tucked away into great marble collections. Here's your chance to own a rare, beautiful and massive example of this great artist's work!
