Artigas, Uruguay, Sawed block of country rock that holds Amethyst veins, with a fascinating scene of the dynamics involved in the geological formation of Amethyst deposits in Basalts. A study in the power deep in the earth. The back shows how the basalt was splintered before a gel solution rich in Silica entered a void in the the basalt, and after Agate was layered over the basalt, amethyst crystals nucleated on the agate and eventually locked in a geode.
