Agate Sphere
While this agate sphere is not very remarkable on first glance, what you will see upon inspection is that it has these simply awesome formations on the "back"! I have no idea what they are, but I've seen them in agate before. Please click on the first and third pics for a better view of this (click first on the thumbnail to the left). It has a diameter of 2.5 inches and weighs 430 grams.
