Here’s a picture of the largest hail stone in terms of weight (1.94 pounds) and diameter (8.0 inches) to ever be preserved. It fell last Friday, July 23rd, in Vivian, South Dakota.

The stone is now at the cold lab at the National Center for Atmospheric Research in Boulder, Colorado.
A hail stone that fell in Aurora, NE a few years ago is still in the record books for greatest circumference, just slightly larger than this stone.
The plan is to make a casting of this stone so that replicas can be displayed in various museums and weather service offices.
