Antarctica’s rare blood-red waterfall isn’t actually made of blood. Instead, it appears as a rare crimson color because the lake it comes from has been preserved under salty ice for years. The lake is rich in iron, too salty to freeze, and has no oxygen. When the iron-rich water comes in contact with the oxygen in the air, it rusts, creating a disturbingly beautiful red color.

Kyawthuite, found in the Mogok region of Myanmar (formerly Burma), is a deep orange crystal that was only officially recognized in 2015, making it one of the rarest minerals on earth.[1] The only sample ever found is a 1.61-carat gem that was thought to be formed in pegmatite.
