Aaaah, droooool, the colors, the COLORS!!! What a fantastic marble, from the scintillating structure of the featured dotted dome to the brilliant colorful design on the backside. An absolute gem of a marble!! All I could think of was that guy throwing that dart in that one commercial where he yells "Mountain Top!" - I know, crazy, but this marble is indeed at the top, ha ha. And looks like a mountain. A VERY cool one....
