Crazy Lace Agates
also called "Laguna Lace"

    The Crazy Lace Agates ("Laguna Lace")  may be one of most well-known agates coming from a main mining site surrounded by many smaller claims (different lace names)  in northern Mexico for they are widely used in many lapidary arts since 1950s. The name "Crazy Lace" refers to the irregular and geometric patterns resulting from agates encrusting and later replacing the large pointy calcite crystals lining the fissures within the limestone formations. Since the miners tend to break up the Crazy Lace agate veins into clunks with explosives and heavy machinary, any agates with whole patterns are somewhat scarce. The most common colors are red, yellow, white, gray and black, but they can come in a wide spectrum of colors (I have yet to see purple color) and often come with excellent shadowing effects. Recently, they have been passed as "Laguna Lace" even they came from the same pit with no relationship with the true Laguna Agates found hundreds of kilometers away.
