“Lace agate is a variety that exhibits a lace-like pattern with forms such as eyes, swirls, bands or zigzags (if these predominate, it is called lattice agate). Crazy lace agate, found in Mexico, is often brightly colored and complexly patterned.” [https://en.wikipedia.org/wiki/Agate]
Crazy lace agate is believed to have been created in the Cretaceous period, about 65-90 million years ago, making it a fairly young stone.
Some say that this is a healing stone. Even if you do not believe that it will surely be a healing experience to create with such a beautiful piece.
