This is easily one of the greatest vortex marbles I have ever laid eyes on. And I have seen a LOT of vortex marbles by now, ha. The multi-layered fuming that stretches down into the depths of this one is some of the craziest glass you will ever see. In hand, the three-dimensionality of it is pure awesomeness. And geez, those fumed colors that Alex achieved, dang, SOOOO nice! Alex didn't stop there though as the backside is almost as equally gorgeous. Those colors and lines and the overall flow of the design is so top notch. This marble flows from top to bottom, inside to out, a true masterpiece! Signed 'Alex C 2015'.
