A polished crazy lace agate sphere from Chihuahua, Mexico, banded in warm gold, grey, and brown with the tight, twisting swirls that give the stone its name. This is a banded chalcedony, the same quartz family as any agate, but crazy lace stands apart for its chaotic, folded banding rather than the neat concentric rings of most agates. Those patterns were laid down layer by layer as mineral-rich water seeped through gas pockets in ancient volcanic rock. Chihuahua is effectively the only place in the world it comes from.
