These are crazy lace agate carved moons. Crazy lace agate (also known as Mexican Agate) is a banded chalcedony (microcrystalline quartz) that's infused with iron and aluminum and is often brightly colored and complexly patterned. This produces the creamy browns, blacks, greys and golds (and occasional pinks or reds) swirled together in this stone. Crazy lace agate is commonly referred to as the "laughter stone," or "happy lace." It's a balancing and protecting stone, believed to ward off the "evil eye," bringing joy and absorbing emotional pain.
