Crystal Earth Sphere/Marble Natural Continents 1.4" - The size of this sphere/marble is approximately 35mm, 1.4". This is the medium 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. It shows our planets mountain ranges, rivers and continents in beautiful detail. The continents are of their true natural color. The detail is wonderful and the color (which varies from marble to marble) is a beautiful ocean blue. 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.
