Mexican Lace Agate is a variety of chalcedony characterized by its complex, swirling patterns and delicate, lace-like banding. It is primarily found as nodular fillings within igneous volcanic rhyolite deposits, often displaying vibrant warm colors. It is highly favored by lapidary artists for its durability and intricate internal structure when cut and polished.

Field specimens usually show a botryoidal, massive, nodular habit, so train your eye for that shape before scanning the outcrop.
