Redditor Proteon posted this photo of a gorgeous polished meteorite sphere. Another user explained that it was a type of meteorite called pallasite, which is "a mixture of iron-nickel metal and olivine, a crystal that makes up the majority of Earth's mantle." Several posters estimated it to be worth #10,000 to $12,000 in value. Provided that information is correct, I need to add that to my Christmas gift wish list. -Via Science Dump
