Here's a suuuper fun and pretty marble in Greg's fibonacci style, with a bottom layer of light blue, and then pink rings, and finally cobalt blue rings on the top layer. Each 'fibonacci hole' has a different murrine peaking out inside. This marble is soooo hard to explore, and there's no way to properly capture the depth and hidden gems with pics. REALLY cool marble! Comes with one of Greg's stands. Signed with 'Greg Chase 2008' sig chip.
