“The stone was not chocolate brown but rather the color of brown sugar. It was 3-4 inches long, 2 inches wide, and had a hump in the middle which made it perhaps 2 inches thick at the thickest point. It was flat on the bottom and had three black, concentric circles on the top 1/2 inch. Below the circles were many small black circles. The stone was not transparent.”
