Fantastic Doug Sweet Art Glass marble with fantastic depth and colors. From what I can see it is about 2 maybe a tad + or – so I included an excess of pictures on a ruler as your eyes see what mine do in terms of judging the size. Condition: Excellent condition with NO scratches NO scuffs and NO concerns of anykind. The Lucite stand is probably older than the marble with a few light scuffs that I believe came off when I cleaned with windex but lucite may have a mark from use.
