This is a beautiful white lace agate with a natural druzy hole with sparkles . Very unique piece . 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.  This stone is believed to promote well being and happiness
