The Gem-Like Turquoise Ice Found on Lake Baikal

Russian photographer Alexey Trofimov calls Lake Baikal "the gem that does not need to be cut." It's the oldest, largest, deepest, and clearest freshwater lake in the world. Every winter, as temperatures plummet to well below zero, the crystal clear lake water forms brilliant gem-like ice that glimmers in the sunlight.
