Some of Geoff's Earth marbles are just more beautiful than others, and this one is a stunner! The blue oceans are incredible and the clouds are perfect. The dichro continents are wild in hand! This one is also a piece of history because it's so early, from clear back in 1990! It's had one owner that entire time and is in the same flawless condition as the day it was made. Super gemmy piece of marble and glass history here! Signed 'Geoffrey Beetem 1990 333'.
