To me, this marble is just a fantastic example of a wonderful theme flowing all through a sphere. It features George's unicorn murrine with LOADS of Unicorn Dust behind it, aka crushed opal, ha. Such a brilliant application, with that opal dust all twisted up in the core and swirling around, sooooo wildly sparkly! Absolute perfection in application. The bottom is awesome too with a nice opal sphere highlighted, and then more sparkly glass surrounding the image and the opal. Brilliant top to bottom and just SO fun. I honestly don't care if this marble ever sells, it's so cool and so hard to let go of!
