Etsy artist TardisTreasures sells these mini snow globes which will cost you about $50(USD) each. They measure about 4 inches tall and 3 inches wide, and you can choose from the 9th Doctor, the 10th Doctor and River Song.
Oddly enough, there’s no Ice Warrior version. Forget that old souvenir New York snow globe on your shelf. Geeky snow globes are the way to go. Does it snow on Gallifrey? I’m not sure, but I know it snows here, and on a winter day you can stay inside and admire your Doctor Who snow globe.
