This is THE ONE - the absolute pinnacle of Ro Purser marbledom, the unbelievable Arte' NeuRo!! And it is a HUGE double row example of this style, as good as you'll ever find from Ro at this 50 year mark in his career! These marbles are amazing achievements in the world of glass, and it is a STAGGERING amount of work all told to bring these spheres into existence! If you want the best of the best of what Ro makes, the absolute mountain top of color craziness in a marble/sphere, then you need one of these in your collection! Each one is unique, painstakingly laid out with a new variety of cane and color, each a brilliant masterpiece. AND - and here's the real kicker - this is a special 50th anniversary edition commemorating FIFTY YEARS of Ro blowing and working with glass! Each of this VERY limited number of marbles has a special 'Ro 50' signature cane in it to mark them as the special pieces that they are. Do NOT miss an opportunity like this, there are NO marbles that are more collectible with future upside than these! Ro is in his 70's now, so he won't be creating these amazing spheres for very much longer, and the wizardry could end at any time now. MASTERPIECE is the word for this sphere here.

Here's a video that shows just a tiny portion of some of the steps Ro takes to make a piece like this. It's like a hundred times more complex than this, but this will give you a feel for it: http://youtu.be/5pNnAkDVHl0
