This is Ro's most famous marble style, if we can call this astounding work of glass art a mere 'marble', ha. Yeah, sphere is probably a better term, and in fact, that's the term Ro prefers to use for his work. The value of these spheres keeps increasing steadily over time, and this marble movement is still young in the grand scheme of things, so this is a great investment opportunity, beyond the shear beauty of this orb and the astounding amount of time it took Ro to create a sphere like this. Ro is also at the very end of his career now, so there won't be many more of these coming. With all of the murrini included here, you are looking at literally years of work to arrive at this finished product. Then there's the question of how Ro even managed to construct a marble like this - you look at it and your mind says HUH??? Truly amazing. This classic beauty was created early in 2020 and is a HUGE example of this style, one of the largest I've sold! This is even MORE SPECIAL than usual because it was created during Ro's 50th year of blowing glass, and so to celebrate, Ro signed it with a special Ro 50 sig chip (last pic). So cool, and HARD to let go of! Always amazing, a MUST for any solid marble collection, taking us clear back to our marble roots! Take a peek inside with some light behind and you are treated to an amazing kaleidoscopic view!! Signed with 'Ro 50' sig chip.
