Named for the painter Pablo Picasso, picasso jasper is not actually a jasper. This stone is the result of limestone deposits undergoing a metamorphic process of intense heat and pressure, which results in its distinct layers and wavy streaks. While most picasso jasper tends to be white or grey, it can also appear in a wide range of colors including red, green, or brown.
