Mmmmm, so nice, that light that flows through this marble just REALLY brings it to LIFE!! The granite style drip webbing of this marble is killer just to study on its own (possibly a new mineral called Sipsite?), but that Lucy fade to Luna core inside is to die for when you hit it with the black light. Such killer colors and patterns emerge, like a dream within a living dream. Really a fascinating marble! Signed 'Sips 17'.
