PICASSO JASPER
Picasso marble was formed when magna covered limestone fields during prehistoric times. The pattern of color is from magma being forced through heat and pressure fractures in the limestone, painting the material with gray and tan colors streaked with black lines. This colorization appeared to be like a Picasso painting, hence the name.
