VTG Alexander Kalifano Mother of Pearl World Globe Desk Office 3” Paperweight

VTG Alexander Kalifano Mother of Pearl World Globe Desk Office 3” Paperweight Pre-owned in good condition. There seems like marking of lines, crack?  to the left of USA but I don't feel it in the surface of the global. Not sure if it's how it was made or a crack from the inside? Please review photos for additional details. As is.
