Found deep inside a mine in southern Chihuahua Mexico, these crystals were formed in a natural cave totally enclosed in bedrock. A geode full of spectacular crystals as tall as pine trees, and in some cases greater in circumference, they are a translucent gold and silver in color and come in many incredible forms and shapes. The Crystal Cave of the Giants was discovered within the same limestone body that hosts the silver-zinc-lead ore bodies exploited by the mine and it was probably dissolved by the same hydrothermal fluids that deposited the metals with the gypsum being crystallized during the waning stages of mineralization.
