Crazy Lace Agate is one of many varieties of cryptocrystalline quartz that fall under the general group referred to as "agate." Crazy Lace tends to have, as the name implies, lacy patterns that are pretty random. Much of the material found on the market today has colors of banding that tends to be various shades of white and gray, while material from older collections displays a wide variety of bright colors, but predominantly reds and browns mixed with whites. Some of the bands in agates can be translucent to transparent. Occasionally agate nodules will have hollows inside that have small drusy quartz crystals projecting from the walls.

I have found that when cutting this stone, sometimes the connection between individual bands is not that strong. When successfully cut, however, it creates beautiful and unique stones with fascinating patterns. From what I understand, this variety of agate is found in Chihuahua, Mexico.
