"Crystal Birth"

Today's bit of beauty, courtesy of Emanuele Fornasier (and This Is Colossal):

These stunning structures are the result of a chemical reaction where the metal is deposited from the solution onto the metal surface. It takes from a few hours to a couple of days to generate a crystal. This process is carried out very slowly by an electric current: layer by layer the crystal is born.
