This is one of those marbles I look at and go, "whoa, how did I never think of a design like that!?" This gem and its companion brother/sister marble that I also have available feature a fire/ice center reticello, laid flat across the middle of the marble, with a juxtaposed fire/ice reticello that is wrapped all around the outside of the marble. What makes it soooo perfect and cool in hand is that Scotty then cut a faceted window on one pole that allows you a sweet viewing window of the opposite retti inside! There is also some sparkle in there shining through, and it's a magical design altogether, wholly unique in the world of marbles! It's another genius homerun design that will shine in your collection, and the pair of these would look KILLER together!
