This marble is big, bold and beautiful, with one of the deepest vortexes I've ever seen, large and in charge! The bottom of this well is pulled waaaay down in there, I couldn't really even get the light to the bottom of it very well for the picture since it needs light directly above it to reach all the way down. It has two neat patterns going on - silver fuming inside, gold fuming outisde. If you like vortexes, then this one is for you, very special in its depth.
