Formation & geological history

Formed during the Cretaceous period approximately 65 to 90 million years ago, primarily in northern Mexico. It was created in volcanic environments where silica-rich fluids filled cavities in lava rocks.

Uses & applications

Predominantly used for lapidary arts, high-quality jewelry cabochons, metaphysical collecting, and decorative carvings.

Geological facts

Also known as Mexican Lace Agate or the Laughter Stone, it is found only in the state of Chihuahua, Mexico. Its intricate zig-zag patterns are thought to resemble the woven lace fabric of the region.

Field identification & locations

Identify by its characteristic 'fortification' patterns and complex, looping bands of color. It is a favorite among rockhounds for its ability to take a high polish. Avoid confusing it with Jasper by checking for translucency in thin slices.
