This is one of the largest examples of Rich's hollow work that you will ever find. This marble is incredible, an amazing glass feat. Because of its size, it seems extra hollow compared to the others, which it is - I guess it's just really cool to hold in hand, rather hard to describe, and needs to be experienced. This marble has heavy gold fuming inside that gives it a beautiful glow, along with all of the other sweet surface adornments. Crazy cool marble!!
