Crystal Earth Sphere/Marble 22K Gold Plate Continents 2" - The size of this sphere/marble is approximately 50mm, 2". This is the largest size that we carry in the crystal Planet Earth sphere/marbles. We are also including the crystal stand to display it on.This marble is made of Austrian Crystal and is Absolutely Gorgeous!!! Anyone who collects Globes or Planets will truly love this marble. The color of the Sphere is a beautiful ocean blue (this color varies from sphere to sphere) and the continents are 22K gold plate. It would make a wonderful gift. It is truly a beautiful and amazing marble. This sphere/marble would be such a nice addition to any marble collection. We have several of our own sitting on our desk and displayed in our home and they are just magical to look at!! This is by far the most beautiful sphere/marble that we carry.
