I don't know the history behind this one, but this is a rare little gem from Raven featuring a fumed implosion inside. I've never seen one like this from Raven before, so very cool to see. My favorite part might be the backside though, as it has a nice encalmo design....which is another thing I've never seen from Raven before, ha. He was probably just showing off with this one, ha. Very fun earthy colors with a moon in the middle. Neat little rare marble! Signed 'Raven 2013'.
